It is an object of the present technology to overcome the disadvantages of conventional chlorination of a copper phthalocyanine which produces copper phthalocyanine, wherein the number of chlorines is less than than or equal to 4. The pigments described herein contain less chlorine than standard commercial grades of tetrachlorinated (or greater) copper phthalocyanine pigments while achieving similar color space, chromaticity, fastness properties, and color travel in automotive waterborne and solvent borne systems. The inventive pigments are more advantageous from a toxicity and environmental perspective, and allow the manufacturer to produce pigments in a safe and economical manner.

The present technology is directed to pigment compositions having a pure, or substantially pure, crystal form, containing less chlorine than standard tetrachlorinated copper phthalocyanine pigments, while giving similar color space, chromaticity, fastness properties, and color travel in automotive waterborne and solvent borne systems. These pigments are more advantageous from a toxicity and environmental perspective, and allow the manufacturer to produce pigments in a safe and economical manner.

The present invention relates to a colorant, a colored resin composition comprising the colorant, and a color filter prepared using the colored resin composition. A novel reddish yellow pigment may be used in combination with a green pigment and a yellow pigment in order to reduce the imbalance of the intramolecular polarization of the green pigment and/or the yellow pigment in the colorant. As a result, a color filter comprising a colored layer in which a light leakage phenomenon, caused by an electric field distortion, is reduced.

A colorant for plastic containing a halogenated phthalocyanine pigment (A) that satisfies conditions (1) to (4) below: (1) the average number of halogen substitutions is at least 2.0 but not more than 7.0, (2) the halogen distribution width is at least 5, (3) the amount of aluminum phthalocyanine and halogenated aluminum phthalocyanine is not more than 1.0% by mass, and (4) the central element is at least one element selected from the group consisting of hydrogen, manganese, iron, cobalt, zinc, nickel and copper. As a result, a colorant for plastic can be shown that can color a resin without changing the mechanical or chemical properties of the resin, and in particular can produce a plastic molded article having essentially no migration, extremely low discoloration due to heat, and no deformation such as warping and distortion.
