Patent ID: 7077896

Claim:
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 represented by the formula (1): 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, —SO 2 NHR, —SO 2 NR 2 , —NR 2 , —CONR 2 , —CONHR or —SR (wherein R represents an alkyl group having 12 to 18 carbon atoms or an alkenyl group having 12 to 18 carbon atoms), and m is an integer of 1 to 4; or formula (2) wherein P represents a phthalocyanine structure, Y is a hydrogen atom or a halogen atom, and n is an integer of 1 to 4.
