Abstract
A method for producing a halogenated zinc phthalocyanine pigment according to one embodiment includes a first step of obtaining a halogenated zinc phthalocyanine crude pigment by deposition by extracting a halogenated zinc phthalocyanine, which is synthesized by using a compound that generates an acid by reacting with water; and a second step of forming the halogenated zinc phthalocyanine crude pigment into a pigment.
Claims7
A method for producing a halogenated zinc phthalocyanine pigment, comprising:
- a step of obtaining a halogenated zinc phthalocyanine crude pigment by deposition by extracting a halogenated zinc phthalocyanine, which is synthesized by using a compound that generates an acid by reacting with water, in a basic aqueous solution;
- and
- a step of forming the halogenated zinc phthalocyanine crude pigment into a pigment.
A halogenated zinc phthalocyanine pigment having a base adsorption amount of 0.13 mol/kg or more and an Al content of 3000 mass ppm or less.
