Abstract
An object is to provide phthalocyanine pigment compositions that have good transparency, gloss, and suitability in the initial viscosity after production as well as outstanding storage stability when used in liquid ink. A copper phthalocyanine pigment composition containing copper phthalocyanine, a rosin compound, copper phthalocyanine sulfonic acid or its salt, and an aliphatic amine with the calcium content of the pigment composition being 200 ppm or less has good transparency, gloss, and suitability in the initial viscosity after production as well as outstanding storage stability when used in liquid ink.
