<p>PURPOSE:To provide a pigment compsn. having excellent non-cohesiveness, by adding a copper phthalocyanine derivative to a highly halogenated copper phthalocyanine. CONSTITUTION:A pigment compsn. is obtd. by adding 0.5-30pts.wt. copper phthalocyanine derivative (A) of the formula [wherein CuPc is a copper phthalocyanine residue; X is Cl, Br; l is 1-12; A is -SO2-, -CO-; R1, R2 are each (substd.) alkyl or forms an N atom-contg. heterocyclic ring when combined together; n, m are each 1-4] to 100pts.wt. highly halogenated copper phthalocyanine (B) such as highly chlorinated copper phthalocyanine. Thought compd. B is an excellent green pigment, the particle size thereof is small and the pigment tends to aggramerate so that it exhibits a high structural viscosity in flow characteristics and there is a possibility that segregation or sedimention is caused when mixed with other kinds of pigments. By adding compd. A, a pigment compsn. having wholly improved non-cohesiveness can be obtd.</p> |
