Abstract
Abstract A phthalocyanine pigment composition comprising a phthalocyanine pigment and a sulphonated phthalocyanine derivative of the formula (RNHSO.sub.2).sub.m --Pc--(SO.sub.3.sup.⊖ N.sup.⊕ H.sub.3 R) n wherein the sum of m and n is 1 to 4 and R is a tertiary alkyl having 18 to 22 carbon atoms, which composition gives very good flow and strength when incorporated into paint and ink application media.
