Copper Free Phthalocyanine Blue Organic Aluminum Phthalocyanine Blue Pigment P. B. 79 for Offset Inks UV Curing Inks Aluminum phthalocyanine is a chemical substance with a molecular formula of C32H18AlClN8 and a molecular weight of 576.9724. It is used to manufacture environmentally friendly phthalocyanine pigments, mainly used in inks, paints, plastics, and can also be used as organic conductors and photoconductors. The output and application range of aluminum phthalocyanine are not as good as those of copper phthalocyanine, but because free metals are harmful to health, Restricted in international environmental regulations and replaced with low-toxic or non-toxic metal phthalocyanines (Al, Zn). Aluminum phthalocyanine can be used for coloring plastics and synthesizing reactive dyes and solvent dyes; aluminum phthalocyanine has special application properties and is used in functional colorants.
