| abstract | PIGMENT COMPOSITIONS Abstract of the Disclosure A pigment composition comprising 80 - 99% weight/ weight of copper phthalocyanine containing 1.5 - 10% weight/ weight of peripherally-bound chlorine, and 20 - 1% weight/weight of a sulphonated copper phthalocyanine derivative having the formula:- I wherein CuPc represents a copper phthalocyanine residue, R1, R2, R3, R4, R5 and R6 arc the same or different and each represents a hydrogen atom, an alkyl group having from 1 to 22 carbon atoms or a cyclic alkyl group having from 5 to 22 carbon atoms, an aryl,aralky,alkaryl or dehydroabietyl group, X represents hydrogen or an alkali metal atom and m, n and p can each be 0 or a value in the range of from 1 to 4. with the proviso that the sum of m, n and p is within the range of from 1 to 4; the composition being characterised by its x-ray diffraction spectrum as resembling the ?-crystal form, and further characterised by the substantial absence of any tendency to crystallise on prolonged contact with aromatic solvents, even at elevated temperatures, which composition, without further pigmentization stages, is suitable for direct incorporation in surface coating media, and provides excellent strength and flow properties therein. - 1a - |
