No. 1-28119 discloses that a crude copper phthalocyanine is kneaded with a grinding aid consisting of a water-soluble inorganic salt such as sodium chloride and a polyol such as diethylene glycol and ethylene glycol, and an organic liquid such as an alcohol or an amine. A kneaded material obtained by pigmentation by a so-called solvent salt milling method, which is wet-milled using a grinder such as Simpson mix muller, is pulverized into water, washed with water, and filtered to obtain a water-soluble inorganic salt. A method for removing an auxiliary agent and an organic liquid to obtain a pigment is disclosed. (2) JP-A-50-157419 and JP-A-52-69435 disclose the use of copper phthalocyanine crude in the absence of a grinding aid and an organic liquid, such as a ball mill and an attritor. By the so-called dry milling method of dry grinding using a grinding machine,
After obtaining the dry milled product of crude copper phthalocyanine, the dry milled product of the crude copper phthalocyanine partially transitions from β-type to α-type with refinement and is strongly aggregated. By heating the dry milled material in which α-type and β-type are mixed with a crystallization solvent such as a mixed solution of water and xylene, or a mixed solution of water and alcohol, the α-type is transferred to β-type, and the crystal particles are converted. A method is disclosed in which a pigment is obtained by dispersing the crystallization solvent in a large size and then distilling off a crystallization solvent by distillation. Β obtained by these methods, etc.
The type copper phthalocyanine pigment has been practically used after being treated with a copper phthalocyanine derivative.
