Description
A synthetic organic material composed of chlorinated copper phthalocyanine (chlorinated Phthalocyanine blue). Phthalocyanine blue was introduced as a industrial pigment in 1935 and the green derivative was first sold in 1938. Phthalocyanine green is usually adsorbed on an aluminum hydrate base to form a deep vivid green color that is used as a substitute for viridian. The permanent pigment is unaffected by light, heat, and chemicals. Phthalocyanine green is used as a colorant in inks, paints, chalks, leather, pencils, and photographs.
