CHLORINATED COPPER PHTHALOCYANINE PIGMENT COMPOSITION FOR COLORING NON-BRONZE PLASTICS AND PREPARATION METHOD

摘要

A chlorinated copper phthalocyanine pigment composition for coloring non-bronze plastics, which belongs to the field of chemical pigments. The chlorinated copper phthalocyanine pigment composition for coloring non-bronze plastics effectively reduces the bronze performance when used on the surfaces of plastics, on the premise of ensuring the color fastness, light resistance, heat resistance, corrosion resistance etc. of a pigment. The pigment composition comprises the following components: 100 parts of chlorinated copper phthalocyanine with an average chlorine substituent number of 0.1-3; and 1-20 parts of CuPc-(Y)n, wherein CuPc represents a copper phthalocyanine residue, Y represents a substituent of a sulfonic acid, a sulfonate, a sulfamate or an alkyl phthalimide, and n represents an average substituent number and is 0.5-3. Further provided is a preparation method for the pigment composition.
