Generally, organic pigments are categorized by their chemical structural types into azo, phthalocyanine, and heterocyclic types, and by color spectrum into yellow, orange, red, purple, blue, green, and others. Among them, azo and heterocyclic pigments mainly include yellow, orange, red, and purple varieties; phthalocyanines dominate the blue and green color spectrum in organic pigments. Phthalocyanine pigments offer excellent properties such as high color fastness, safety, environmental friendliness, and are relatively cost-effective, making them irreplaceable organic pigments in the blue and green color 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.
