PIGMENT COMPOSITION COMPRISING PHTHALOCYANINE, HALOGENATED PHTHALOCYANINE AND PHTHALOCYANINE DERIVATIVE, COLORANT USING THE COMPOSITION, AND MOLDED PRODUCT OBTAINED FROM PLASTIC CONTAINING THE COLORANT

摘要

A pigment composition composed of 50 to 95% by weight of a phthalocyanine, 1 to 45% by weight of a halogenated phthalocyanine of which the number of substituents of a halogen atom is 1 to 9 and the average number of the substituents is 2.0 to 4.0 and 0.1 to 10% by weight of a phthalocyanine derivative of the formula (1) or a phthalimide methylated phthalocyanine derivative, a colorant containing the above pigment composition and a molded article obtained from a plastic containing the above colorant,P-(X)m  (1)wherein P represents a phthalocyanine structure, X represents an alkyl group having 12 to 18 carbon atoms, an alkoxy group having 12 to 18 carbon atoms, —SO₂NHR, —SO₂NR₂, —NR₂, —CONR₂, —CONHR or —SR (wherein R represents an alkyl group or an alkenyl group which has 12 to 18 carbon atoms), and m is an integer of 1 to 4.
