Disclosed are: copper phthalocyanine pigments which each contain at least one kind of copper phthalocyanine microparticles that has high spectral characteristics and that is in a crystal form other than ±-form; and processes for the production of the copper phthalocyanine microparticles. Provided are: a copper phthalocyanine pigment which contains at least one kind of copper phthalocyanine microparticles that is in a crystal form other than ±-form and that exhibits, in a region of 380 nm to 780 nm, an absorption spectrum shape extremely similar to that of ±-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 that is in a crystal form other than ±- or µ-form and that exhibits a wavelength (»max) of shorter than 478 nm in the transmission spectrum in a region of 380 nm to 780 nm, said wavelength (»max) being a wavelength at which the maximum transmittance appears; and a process for the production of the copper phthalocyanine microparticles. |
