    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 ?m, an average scattering intensity at scattering angles 2? 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.
