ABSTRACT:
The invention provides a composition comprising particles of an optionally halogenated phthalocynine (a); from 0.5 to 10% weight, preferably from 2 to 8% by weight, based on the optionally halogenated phthalocyanine (a), or a vinylic or acrylic polymer (b); and from 1 to 15% by weight, preferably from 3 to 10% by weight, based on the optionally halogenated phthalocyanine (a), of an optionally halogenated phthalocyanine (c) which is outside the particles of the optionally halogenated phthalocyanine (a) and is substituted by a group comprising at least 1 hetero atom selected from the group consisting of N, O, S and P and at least 3 carbon atoms. The instant compositions comprising three essential components are surprisingly warpfree in substrate such as partially crystalline plastics, especially those processed by injection moulding. Geometrically identical parts of different colours are obtained.
