Abstract: The invention comprises a phthalocyanine pigment mixture in the a -form consisting of an intimate mixture of at least 80% of copper phthalocyanine or a mono-halogen copper phthalocyanine or a mixture of these two components, 0.5 to 10% of tin phthalocyanine and 0.5 to 10% of magnesium phthalocyanine. The mixtures are made by grinding the components together in the presence of sodium sulphate, chloride or acetate and for example isopropanol or in aqueous dispersion with hexachlorethane. The components may also be conditioned separately and mixed together, or the mixture may be synthesized by heating phthalonitrile or phthalic anhydride or phthalimide and urea with a mixture of salts or oxides of copper, tin and magnesium or by heating phthalonitrile with magnesium and heating the produce with copper and tin salts and then conditioning the mixture by grinding in aqueous dispersion with hexachloroethane and/or by heating with dilute sulphuric acid. Examples are given. The pigments colour lacquers and spinning solutions. Specification 971,044 is referred to.

Abstract: The invention comprises copper phthalocyanine pigments in the a -form and in a state of dispersion suitable for pigmenting purposes which comprise intimate mixtures of at least 80% of copper phthalocyanine and/or copper monobromo- or monochloro-phthalocyanine, 0.5 to 10% of tin phthalocyanine and 0.5 to 10% of cobalt phthalocyanine. Small proportions tions of other metal phthalocyanines may be present. The tin and cobalt phthalocyanines specified are dichloro-tin, hydroxy-tin and chloro-cobalt phthalocyanines. The pigments are made by grinding the a - or b -form of the copper phthalocyanine and/or copper mono-chloro- or mono-bromo-phthalocyanine, tin phthalocyanine and cobalt phthalocyanine to produce the a -form before, during or after mixing them together. Grinding may be conducted in the presence of an inorganic or organic salt or a solid organic compound capable of subliming. Mixing may be effected by grinding or acid-pasting the components together or by synthesizing them together. A mixture of the pigments in b -form may also be converted to the a -form by acid-pasting from concentrated sulphuric acid. Examples are given. The pigments are crystallization- and flocculation-resistant. Specification 971,044 is referred to.
