Pigments
Phthalocyanine (PC) pigments constitute a broad
class of pigments. PC Blue and PC green are among the most important organic
pigments.
Copper phthalocyanine blue is the copper (II) complex of tetra aza tetra
benzoporphine (CPC) whereas Phthalocyanine green is its chlorinated
derivative (Pigment green 7). The brominated derivative of CPC provide a
yellowish green shade(Pigment green 36).
The specific crystal modification decide 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). The Alpha modification which is phase
stabilised by partial chlorination called solvent stable alpha blue or
Pigment Blue15:1.
The Alpha modification which is stabilised towards flocculation and the
phase change are registered as Pigment Blue 15:2. These pigments find use in
paints.
The details of the individual class of pigments together with its
application is given separately.
