Abstract
This invention relates to water-dispersible phthalocyanine pigment formulations that are mixtures of PA1 (a) about 60 to about 99.5% by weight, based on the total amount of components (a) and (b), of a conditioned metal phthalocyanine pigment, and PA1 (b) about 0.5 to about 40% by weight, based on the total amount of components (a) and (b), of a water-insoluble sulfonated phthalocyanine having the formula EQU Pc(SO.sub.2 OR).sub.x (I) wherein PA1 Pc represents a phthalocyanine moiety; PA1 R is H or M, wherein M is a monovalent metal, divalent metal, trivalent metal, or ammonium cation, and PA1 x is a from about 0.2 to about 4.
