Abstract
Provided are: a copper phthalocyanine pigment which contains at least one kind of copper phthalocyanine microparticles whose crystal type is any of two kinds of β- and γ-type crystals and that exhibits, in a region of 380 nm to 780 nm, an absorption spectrum shape extremely similar to that of α-form copper phthalocyanine microparticles; and a process for the production of the copper phthalocyanine microparticles. Also provided are: a copper phthalocyanine pigment which contains at least one kind of coper phthalocyanine microparticles whose crystal type is any of two kinds of β- and γ-type crystals and that exhibits a wavelength (λ-max) of shorter than 478 nm in the transmission spectrum in a region of 380 nm to 780 nm, said wavelength (λ-max) being a wavelength at which the maximum transmittance appears; and a process for the production of the copper phthalocyanine microparticles.
