Abstract: A method for producing a halogenated zinc phthalocyanine pigment includes a step of forming a halogenated zinc phthalocyanine crude pigment into a pigment. The halogenated zinc phthalocyanine crude pigment is obtained by depositing a halogenated zinc phthalocyanine, which is synthesized by using a compound that generates an acid by reacting with water, and the aforementioned step includes a pretreatment step of dry-crushing the halogenated zinc phthalocyanine crude pigment by using an attritor and then washing the dry-crushed halogenated zinc phthalocyanine crude pigment with water.

Abstract: There is provided a novel halogenated zinc phthalocyanine pigment for a color filter, which can form a green color filter having excellent contrast and high luminance. A halogenated zinc phthalocyanine pigment for a color filter shows, in a Raman spectrum, a peak intensity of 3.0% or more at 716±2.2 cm−1 when a peak intensity at 650±10 cm−1 is regarded as 100%.

Abstract: The halogenated zinc phthalocyanine pigment is for use as a green pigment for color filters and capable of achieving high brightness. In the halogenated zinc phthalocyanine pigment, when a coating film containing 1.00 part by mass of the pigment, 0.95 parts by mass of a benzyl methacrylate-methacrylic acid copolymer, and 0.30 parts by mass of a dimethylaminoethyl methacrylate copolymer is heated at 230° C. for one hour to form an evaluation coating film having a thickness of 4 μm, an average scattering intensity at scattering angles 2θ in a range of 17° to 21° is determined from a two-dimensional scattering image obtained by GI-WAXS measurement of the evaluation coating film, and a normalized average scattering intensity is determined such that the average scattering intensity at an azimuth of 45° is 1, the normalized average scattering intensity at azimuths of 5° to 89° is 0.70 to 1.15.
