Generally, organic pigments can be categorized by their chemical structural types into azo, phthalocyanine, and heterocyclic classes, and by color spectrum into yellow, orange, red, purple, blue, green, and so on. Among them, azo and heterocyclic pigments mainly include yellow, orange, red, and purple varieties; phthalocyanine pigments dominate the blue and green color spectrum of organic pigments. Phthalocyanine pigments combine excellent durability, high color fastness, safety, and environmental friendliness with relatively economical pricing, making them irreplaceable organic pigments in the blue and green color spectrum. Currently, the production of phthalocyanine pigments accounts for about 28% of the total organic pigment production. With the increasing environmental protection requirements and the development of specialized pigment varieties, it is anticipated that the demand for the phthalocyanine series pigments will continue to rise, presenting good development potential.
