Generally, organic pigments can be classified into azo, phthalocyanine, and heterocyclic types based on their chemical structural types, and into yellow, orange, red, purple, blue, green, and other types based on the color spectrum. Among them, azo and heterocyclic pigments are primarily yellow, orange, red, and purple varieties; phthalocyanine types dominate in the blue and green spectrum of organic pigments. Phthalocyanine pigments offer excellent durability, high color fastness, safety, and environmental protection, and are relatively economical, making them an indispensable organic pigment in the blue and green spectrums today. 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 types, it is expected that the demand for phthalocyanine series pigments will continue to rise and possess great development potential.
