1. A copper phthalocyanine pigment composition comprising:
a copper phthalocyanine pigment;
a copper phthalocyanine sulfonic acid derivative represented by general formula (I),
![]() [in the formula, n represents an average number of substituents of 0.5 to 1.5];
a copper phthalocyanine derivative represented by general formula (II),
![]() [in the formula, R1 represents a C1-C20 alkyl group, and n represents an average number of substituents of 0.5 to 1.5]; and
a copper phthalocyanine derivative represented by general formula (III),
![]() [in the formula, R2, R3, R4, and R5 each independently represent a C1-C20 alkyl group, at least one of R2, R3, R4, and R5 is a C6-C2G alkyl group, and n represents an average number of substituents of 0.5 to 1.5],
wherein the content of the copper phthalocyanine sulfonic acid derivative represented by the general formula (I) is 2% by mass or more and 4% by mass or less in the entire pigment composition, the content of the copper phthalocyanine derivative represented by the general formula (II) is 5% by mass or more and 6% by mass or less in the entire pigment composition, and the content of the copper phthalocyanine derivative represented by the general formula (III) is 0.5% by mass or more and 5% by mass or less in the entire pigment composition.
