EP 1 146 094 B1 Printed by Jouve, 75001 PARIS (FR) EP 1 146 094 B1 Description Field of the Invention 5 [0001] The present invention relates to a process for preparing a water-based pigment dispersion excellent in dis- persibility in water and dispersion stability with the passage of time. The pigment dispersion may be used in an inkjet recording liquid excellent in light resistance, water resistance and hue after printing and excellent in ejection stability in a nozzle. 10 Prior Art of the Invention [0002] In a water-based ink or a water-based coating composition, conventionally, a pigment is dispersed in water by the use of a surfactant or a dispersing resin. However, the surfactant has a problem of the occurrence of foams. When an anti-foaming agent is used in combination for preventing the occurrence of foams, a problem of a decrease in leveling 15 properties occurs. Further, the dispersing resin is effective for a pigment dispersion having a relatively high viscosity, but the dispersing resin exerts only a limited effect on a pigment dispersion having a low viscosity. [0003] There are known methods of dispersing a pigment in water by the use of a dye soluble in water or a pigment derivative. For example, JP-A-56-155261 and JP-A-56-155262 disclose a water-based pigment dispersion containing a pigment and a dye having the same color tone as the color tone of the above pigment. According to the above method, 20 part of the dye is adsorbed on the surface of the pigment, whereby the dispersion stability of the pigment in water is improved. However, when a coating composition or an ink is prepared therefrom, a problem of a color mixture or bleeding occurs since solubility of the dye in water is too large as compared with the affinity of the particle surfaces of the pigment. [0004] JP-A-10-36741 discloses a water-based pigment dispersion containing a phthalocyanine pigment and a phthalocyanine compound into which a carboxylic acid group is introduced. According to the above method, the problem 25 of bleeding is improved. However, a problem is still present in the dispersion stability of a pigment. JP-A-11-49974 discloses a water-based pigment dispersion comprising a pigment and a pigment derivative into which a sulfonic acid group bonding to an inorganic ion is introduced. According to the above method, the dispersion stability of the pigment is secured due to the electrostatic repulsion of divalent metal ion forming a salt with the sulfonic acid group of the pigment derivative integrated with the pigment. However, it is difficult in view of production technology to 30 control the dispersion dispersibility by a trace quantity of the divalent metal ion which is immixed in a pigment-dispersing step. EP 0 787 775 discloses water-dispersible phthalocyanine pigment formulations which are mixtures of conditioned metal phthalocyanine pigment and a water-insoluble sulfonated phthalocyanine. EP 0 636 666 discloses pigment preparations with at least one organic pigment and at least one perylene derivative. 35 US 5 271 759 discloses pigment compositions comprising a) at least one organic pigment; b) 0.05 to 10 % by weight of a modified organic pigment; and c) 0.05 to 10 % by weight of a polymeric ammonium salt of molecular weight 500 to 2,500,000 based on the pigment of a) and which is soluble in water or a lower alkanol. EP 0 851 005 discloses an agglomerated pigment comprising (1) an organic pigment; (2) a sulphonated organic pigment; (3)univalent inorganic counter ions bonded to sulphonic groups of (2); and (4) bivalent or higher inorganic counter ions 40 bonded to sulphonic groups of (2). EP 0 659 842 discloses a pigment composition comprising an organic pigment and a dioxazine pigment derivative represented in the form of a free acid. [0005] Concerning an inkjet recording liquid, the diameter of a printer nozzle decreases with an increase in the resolution of a printer. It is therefore required to decrease the diameter of pigment particles so as to form fine particles. However, 45 when an inkjet recording liquid contains a pigment, it is difficult to satisfy requirements for an inkjet recording liquid such as ejection properties in a nozzle, re-solubility (dispersibility) and color development after printing, at the same time. Summary of the Invention 50 [0006] It is an object of the present invention to provide a process for preparing water-based pigment dispersion excellent in dispersibility in water and stability in storage with the passage of time and a process for the production thereof. It is another object of the present invention to provide a pigment type inkjet recording liquid which is excellent in ejection stability in a nozzle when used as an inkjet recording liquid and has a sufficient color reproduction range when used for printing and which has compatible properties of excellent water resistance and excellent light resistance. 55 [0007] According to the present invention, there is provided a process for preparing an aqueous pigment dispersion comprising 3 to 30 parts by weight of a sulphonic acid-group containing derivative of a pigment and 100 parts by weight of a pigment which is the same pigment type as the derivative, wherein at least part of the pigment derivative is present, in the dispersion, in the form of a sulfonic acid salt selected from an ammonium salt, an organic amine salt and a salt 2 EP 1 146 094 B1 with a monovalent metal, provided that at least 15% of the sulphonic acid groups do not form a salt with the monovalent metal, and wherein the dispersion contains 500 ppm or less of solid metal ions having a valence of at least 2, which process comprises: 5 (I) (a) sulphonating a fused polycyclic pigment to introduce thereon at least one sulfonic acid group and treating the thus obtained reaction product by removing pigment derivatives having at least two sulfonic acid groups from the reaction product; or 10 (b) coupling a base component and a coupling component wherein either the base component or the coupling component has one sulfonic acid group, to produce an azo pigment derivative or a benzimidozolone pigment derivative having one sulfonic acid group in each molecule; 15 (II) dispersing in water (i) the thus obtained pigment derivative and (ii) a pigment of the same type as the pigment derivative in (i). The aqueous pigment dispersion produced by the process of the invention may be used in an inkjet recording liquid. 20 Detailed description of the Invention [0008] The pigment used in the present invention is selected from fused polycyclic pigments such as phthalocyanine pigments, quinacridone pigments, quinacridonequinone pigments, isoindolinone pigments, quinophthalone pigments, diketopyrrolopyrrole pigments, perylene pigments, perinone pigments, indigo pigments, thioindigo pigments, dioxadine 25 pigments, anthraquinone pigments, pyranthrone pigments, anthanthrone pigments, flavanthrone pigments, indanthrone pigments and metal complex pigments, and organic pigments such as benzimidazolone pigments, insoluble azo pig- ments, fused azo pigments and soluble azc pigments. [0009] The pigment includes a compound having a substitute in an unselective substitutable position of a pigment molecule skeleton which forms any one of the above pigments. The above substitute includes lower alkyl groups such 30 as methyl and ethyl, lower alkoxy groups such as methoxy and ethoxy, halogen elements such as chlorine and bromine, a halogen-substituted alkyl group, a carboxylate group, an acetyl group and a hydroxyl group. [0010] Specific examples of the pigment used in the present invention will be shown hereinafter according to C.I. pigment numbers.

Pigment Violet 29 (Anthra[2,1,9-def:6,5,10-d'e'f']diisoquinoline- 1,3,8,10(2H,9H)-tetrone) (hereafter PV29) being prepared under section 6(b)(4) of the Toxic Substances Control Act (TSCA) as amended by the Lautenberg Act, enacted on June 22, 2016.1 Executive Summary Under TSCA § 6(b)(4)(A), EPA must determine whether PV29 “presents an unreasonable risk of injury to health or the environment, without consideration of costs or other nonrisk factors, including an unreasonable risk to a potentially exposed or susceptible subpopulation identified as relevant to the risk evaluation by the Administrator, under the conditions of use.” In reaching that determination, TSCA §§ 26(h) and (k) require that EPA use the best available science and consider all reasonably available information. Under its own regulations, EPA has defined “reasonably available information” to include information that EPA “can reasonably generate, obtain, and synthesize for use in risk evaluations.” 40 C.F.R. § 702.33. In its draft risk evaluation, EPA concludes that PV29 does not present an unreasonable risk. As detailed in our comments below, EPA’s draft risk evaluation cannot support that conclusion because EPA lacks sufficient information to characterize the hazards, exposures, and risks presented by PV29.

  • Comments to EPA on Revised Draft
    UNITED STATES ENVIRONMENTAL PROTECTION AGENCY Comments of Safer Chemicals Healthy Families, Defend Our Health, Earthjustice and Natural Resources Defense Council on EPA’s Revised Draft Risk Evaluation for C.I. Pigment Violet 29 under Section 6(b) of TSCA Submitted via Regulations.gov (December 19, 2020) Docket ID EPA-HQ-OPPT- 2018-0604 Safer Chemicals Healthy Families (SCHF), Defend Our Health, Earthjustice and Natural Resources Defense Council (NRDC) submit these comments on the Environmental Protection Agency (EPA) revised draft risk evaluation for C.I. Pigment Violet 29 (PV29) under section 6(b) of the Toxic Substances Control Act (TSCA).1 Our organizations are committed to assuring the safety of chemicals used in our homes, workplaces and the many products to which our families and children are exposed each day. We took a leadership role during the TSCA legislative process, advocating the most protective and effective legislation possible to reduce the risks of toxic chemicals in use today. The draft revised PV29 evaluation is a significant improvement on the initial draft and recognizes the serious risks of lung overload and toxicity to workers who inhale PV29 dust. We support EPA’s proposed determinations of unreasonable risk to workers for this endpoint but believe they must be strengthened to fully recognize the magnitude of the risk and coupled with testing to fill vital data gaps. As we demonstrate in these comments: • EPA is seeking a limited “letter review” of the revised draft evaluation by a small subset of its Science Advisory Committee on Chemicals (SACC) and eliminating the public comment process normally part of SACC review.
