Generally, organic pigments are categorized by their chemical structural types into azo, phthalocyanine, and heterocyclic types, and by their 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 spectrum of organic pigments. Phthalocyanine pigments combine excellent durability, high color fastness, safety, and environmental protection with relatively economical pricing, making them an indispensable organic pigment in the blue and green 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 expected that the demand for phthalocyanine series pigments will continue to rise, and they have good development potential.
