Generally, organic pigments are classified by their chemical structural types into azo, phthalocyanine, and heterocyclic categories, 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; phthalocyanines dominate 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 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 anticipated that the demand for phthalocyanine series pigments will continue to rise, and they possess good development potential.
