Method for making metal phthalo-cyanine pigments

Claim 1

THE METHOD FOR PRODUCING METAL PHTHALOCYANINE PIGMENTS WHICH COMPRISES HEATING IN THE PRESENCE OF AN INERT ORGANIC HIGH BOILING POINT SOLVENT A PHTHALOCYANINE FORMING METAL DONOR REAGENT SELECTED FROM THE GROUP CONSISTING OF COPPER, NICKEL, IRON, COBALT, VANADIUM, TIN, CHROMIUM, LEAD, ALUMINUM, CADMIUM, MAGNESIUM AND ZINC AND THEIR SALTS, A PHTHALOCYANINE FORMING MATERIAL SELECTED FROM THE GROUP CONSISTING OF PHTHALIC ACID, PHTHALIC ANHYDRIDE. THE METHYL AND ETHYL ESTERS OF PHTHALIC ACID AND PHTHALIC ANHYDRIDE AND THEIR MONO-, DI-, TRIAND TETRA-BROMO AND -CHLORO AND ALKOXY DERIVATIVES AND MIXTURES THEREOF. A PHTHALOCYANINE NITROGEN DONOR SELECTED FROM THE GROUP CONSISTING OF UREA, BIURET, GUANIDINE, GUANYLUREA, DICYANDIAMIDE AND CYANURIC ACID AND AT LEAST A MINOR MOLAR AMOUNT COMPUTE AS METALLIC IONS AND AS COMPARED TO THE OTHER REACTANTS PRESENT AND SUFFICIENT TO CATALYZE THE PHATHALOCYANINE REACTION TO FORM SAID PIGMENT OF AT LEAST ONE HYDROLYZABLE ESTER HAVING THE FORMULA E(OR)X WHERE E IS AN ELEMENT SELECTED FROM THE GROUP CONSISTING OF TITANUM AND ZIRCONIUM, WHERE O IS OXYGEN, WHERE R IS SELECTED FROM THE GROUP CONISTING OF ALKYL, ARYL, ALKARYL AND ARALKYL RADICALS AND WHERE X CORRESPONDS TO THE VALENCE OF E AND MIXTURES THEREOF TO A TEMPERATURE AND FOR A TIME SUFFICIENT TO FORM A PHATALOCYANINE PIGMENT.
