However, there is a need Chem. 2 for improvements, because the occurrence of crosstalk or 40 Formula (II) ghost images may be observed. R21 Therefore, the present invention has been made in view of the above conventional problems, and it is an object of the present invention to reduce crosstalk and ghost images of the Dye-L L-Dye Stereoscopic image printed matter. More specifically, the 45 present invention is intended to provide a stereoscopic image printed matter with reduced crosstalk or ghost images, a R22 Stereoscopic image printing paper capable of printing the Stereoscopic image, and a method for providing the same (In Formula (II), R and R° each represent a hydrogen Stereoscopic image printed matter. 50 atom, an alkyl group, an alkoxy group, or a substituent rep As a result of various investigations, the inventors of the present invention have discovered that although the foregoing resented by -L’-Y, provided that at least one of R and R’ related art describes the delineation of a right eye pixel and a represents a group other than a hydrogenatom; L represents left eye pixelona planar sheet, the formation of a desired right an alkylene group wherein one CH group or two or more eye pixel and left eye pixel may fail depending on the nature 55 non-adjacent CH groups present in the alkylene group may of a planar sheet, which is responsible for the occurrence of be substituted by —O , —COO ... —OCO —OCOO . crosstalk and ghost images.
