Abstract :
Organic pigments are cost-effective, non-toxic, and possess good color strength, which makes them good choice for their use across various end-use sectors. Copper phthalocyanine (CPC) blue is the copper (II) complex of tetra aza tetra benzoporphine (CPC) whereas phthalocyanine green is its chlorinated derivative. The brominated derivatives of CPC provide a yellowish green shade. The specific crystal modification decides the hue of the product as in Alpha Blue-red shade copper phthalocyanine (Pigment Blue 15) and in Beta Blue-green shade blue (Pigment Blue 15:3). CPC Blue is an upstream product and is a raw material used for the manufacture of our Pigment Blue and Pigment Green products. CPC Blue is also sold to other manufacturers of pigments including a related party for the manufacture of textile dyestuffs. Here we have presented the manufacturing process of two organic pigments – CPC Green and Blue.
