| Résumé : |
Copper phthalocyanine pigments have been rulling the pigment industry ever since their commercialization. They exhibit excellent brilliant shades, high tinting strength, low cost and high performance. Copper phthalocyanine pigment is first discovered accidently in the year 1907 by Braun and Tchermiac. Copper phthalocyanine pigment obtained by reacting phthalic anhydride , urea, cuprous and high boiling solvents in presence of ammonium molybdate as a catalyst, product se obtained is called crude CPC. The phthalocyanine molecule is structurally similar to that of porphine. Chemically one can call copper phthalocyanine the copper complex of tetraazatetrabenzoporphine. The central metal atom is covalently bonded with two nitogens of the porphine ring and aise has co-ordinate linkage with two other nitrogens of the same ring. CPC is available in various isomeric crystals forms, they are named as a, b,Y, d, and e. Various grades of copper phthalocyanine pigments are available commercially depending upon the crystal form of CPC. Pigment blue 15.3 is widely used blue pigment which is b form, CPC. |
