| titleOfInvention | Copper phthalocyanine pigment process |
| abstract | Premilled semichloro copper phthalocyanine or partially sulfonated semichloro copper phthalocyanine is slurried and stirred with sulfuric acid (50-60% and preferably 55-59% in the case of semichloro copper phthalocyanine and 50-61% and preferably 58-61% in the case of partially sulfonated semichloro copper phthalocyanine) at 50°-85° C., preferably 65°-75° C. for 1/2 to 4 hours. The slurry is diluted with to less than 35% sulfuric acid concentration and stirred at 60°-95° C. for 1/2 to 4 hours. The resulting highly transparent pigment is filtered and dried. |
