Summary:Metal-free, copper, cobalt, or nickel phthalocyanines (raw or precipitated, halogen-free or mono-halogenated) are milled with salts which can be subsequently removed by means of a solvent in presence of solid aromatics or araliphatic hydrocarbons melting at over 20 DEG C. or solid derivatives of aromatic or araliphatic hydrocarbons melting at over 20 DEG C. and derived from the basic hydrocarbon by replacement of a single one to at most half of the aromatically bound hydrogen atoms by halogen, nitro, or ether groups, and then removing the grinding substrata. As salts may be used sodium sulphate, acetate, or carbonate, potassium aluminium sulphate, sodium ferrocyanide, barium, calcium, or sodium chloride, and the hydrocarbons employed are preferably such as are volatilized in steam. A dispersing agent may be added. In examples, (1) raw copper phthalocyanine is milled with calcium chloride, sodium acetate, naphthalene, and glycerine monooleic acid ester; (2) precipitated copper phthalocyanine is milled with sodium acetate, sodium carbontae, diphenyl, and lauroyl isopropanol amide (the diphenyl may be replaced by diphenylmethane or naphthalene); (3) monochloro copper (or metal-free or cobalt) phthalocyanine is milled with sodium sulphate, p-dichlorobenzene (or 1, 2, 3-trichlorobenzene or diphenyl) and sodium acetate; (4) metal-free phthalocyanine is milled with calcium chloride, p-nitrotoluene (or p-dinitrobenzene or naphthalene) and glycerine monooleic acid ester; (5) cobalt phthalocyanine is milled with sodium carbonate and acetate, 2-methoxynaphthalene (or ethoxynaphthalene or naphthalene) and lauroyl isopropanol amide; (6) nickel phthalocyanine is milled with sodium chloride, sodium acetate, glycerine mono-oleic acid ester, and 2, 3 dimethylnaphthalene, naphthalene, or p-dichlorobenzene.
