Generally, organic pigments are categorized by their chemical structural types into azo, phthalocyanine, and heterocyclic classes, and by color spectrum into yellow, orange, red, purple, blue, green, and others. Among them, azo and heterocyclic pigments are mainly 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 friendliness, and are relatively cost-effective, making them irreplaceable organic pigments 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.
