Optical brightener KSN and OB-1 have similar chemical structures, and Optical brightener KSN has better whitening effects on PC and plastics than OB-1, and its compatibility is also better than OB-1.Optical brightener KSN also has high temperature resistance. But it is also more light and weather resistant than OB-1. Optical Brightener KSN mainly used in whitening of polyester, polyamide, polyacrylonitrile fiber, the plastic film and all plastic pressing process. Can suitable for synthesizing high polymer including polymeric process.

Phthalocyanine blue is also known as Copper Phthaloc yanine blue; Monstral Fast blue; Winsor Blue; Bocour blue; Talens Rembrandt Blue; Thalo Blue; Heliogen Blue.Phthalocyanine blue is a permanent pigment which is unaffected by light, heat, and chemicals. It is used as a colorant in inks, enamels, plastics, paints, chalks, leather, pencils, and photographs. In industry, phthalocyanine blue has replaced all other blue pigments for use in coatings because it is lightfast as well as resistant to chemicals and clumping.
A synthetic organic colorant composed of copper phthalocyanine that was first synthesized in 1933. In 1935, copper phthalocyanine called Monastral blue [ICI] was marketed as a paint pigment .
The organic colorant is usually adsorbed on an aluminum hydrate base to form a deep blue color. Other colors are achieved by varying the formulation, i.e., chlorinated copper phthalocyanine produces a green colorant.

Pigment Green 7 is a water-dispersed pigment that is particularly light-resistant, produces strong phthalate green, and is specially used for pulp coloring. It is easy to use and does not need to be rinsed. It has high factorial strength and excellent resistance to solvents, heat, light, and weathering. In order to ensure the maximum color strength and adhesion to the pulp, a retention aid must be added to the pulp before adding pigments. It’s phthalocyanine green. Widely used in coating industry, plastic industry, textile industry, ink industry, leather industry, coating industry, paper industry, rubber industry.
