Phthalocyanine Blue BN, also called phthalo blue, phthalocyanine blue, C.I. Pigment Blue 15:2, Copper phthalocyanine blue, Copper tetrabenzoporphyrazine, Cu-Phthaloblue, and C.I. 74160, is a bright, greenish-blue crystalline synthetic blue pigment from the group of phthalocyanine dyes. It was developed as a pigment in the mid- 1930s. Its brilliant blue is used in paints and dyes. It is highly valued for its superior properties such as light fastness, tinting strength, covering power and resistance to the effects of alkalies and acids. It has the appearance of a blue powder, insoluble in water and most solvents. ...more on Wikipedia about "Phthalocyanine Blue BN"

The copper phthalocyanine dyes are produced by introducing solubilizing groups, such as one or more sulphonic acid functions in CPC structure . These dyes find extensive use in various areas of textile dyeing (Direct dyes for cotton), for spin dyeing and in paper industry. Direct blue 86 is the sodium salt of CPC- sulphonic acid whereas direct blue 199 is ammonium salt of the CPC-sulphonic acid. ...more on Wikipedia about "Phthalocyanine dyes"
