More Information
Summary:The present invention relates to a method for manufacturing a halogenated zinc phthalocyanine pigment, including a step of pigmenting a halogenated zinc phthalocyanine crude pigment, in which the halogenated zinc phthalocyanine crude pigment is obtained by precipitation of the halogenated zinc phthalocyanine synthesized from a compound that reacts with water to produce acid. The aforementioned step includes a pretreatment step of using a grinder to dry-pulverize the halogenated zinc phthalocyanine crude pigment, and then washing the dry-pulverized halogenated zinc phthalocyanine crude pigment with water.
