Generally, organic pigments can be categorized by their chemical structural types into azo, phthalocyanine, and heterocyclic types, and by color spectrum into yellow, orange, red, purple, blue, green, and so on. Among them, azo and heterocyclic pigments mainly consist of yellow, orange, red, and purple varieties; phthalocyanine pigments dominate in the blue and green spectrum of organic pigments. Phthalocyanine pigments offer excellent durability, high color fastness, safety, and environmental friendliness, and are relatively economical, making them indispensable 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 continuous increase in environmental protection requirements and the development of specialized pigment types, it is expected that the demand for phthalocyanine series pigments will continue to rise, and they have great development potential.
