    Abstract: The invention comprises phthalocyanine pigment mixtures containing 0.5-10 mole per cent of a phthalocyanine of the formula where Pc is a phthalocyanine radical, R1 is hydrogen or a substituted or unsubstituted aliphatic hydrocarbon radical, R2 is a substituted or unsubstituted aliphatic hydrocarbon radical or, when taken together with R1, a heterocyclic ring, and n is a number from 1-4. The mixtures are made by (a) simply mixing the phthalocyanine of the above formula with a phthalocyanine not resistant to flocculation, for example during acid pasting, by grinding, by heating together in an organic solvent or by preparing a suspension of the phthalocyanine not resistant to flocculation in an aqueous solution of the hydrochloride of the phthalocyanine of the above formula and adding sodium hydroxide, (b) synthesizing phthalocyanines using phthalic acid derivatives a proportion of which contain a radical of the formula or (c) partially chloromethylating a phthalocyanine and reacting the mixture obtained with an amine of the formula Examples are given. Specification 761,718, U.S.A. Specification 2,547,972, and German Specification 1,097,596 are referred to.
