Description
A synthetic organic colorant composed of copper phthalocyanine that was first synthesized in 1933 by R.P.Linstead. In 1935, copper phthalocyanine was marketed as a paint pigment called Monastral blue [ICI]. The organic colorant is usually adsorbed on an aluminum hydrate base to form a deep blue color. Other colors are achieved by varying the formulation, i.e., chlorinated copper phthalocyanine produces a green colorant. Phthalocyanine blue is a permanent pigment which is unaffected by light, heat, and chemicals. It is used as a colorant in inks, enamels, plastics, paints, chalks, leather, pencils, and photographs. In industry, phthalocyanine blue has replaced all other blue pigments for use in coatings because it is lightfast as well as resistant to chemicals and clumping.
