| titleOfInvention | PROCESS TO PREPARE FTALOCIANINE COMPOUNDS. |
| abstract | A process for preparing a mixture of copper phthalocyanine dyes of Formula (I): CuPc (SO3M) x (SO2NH2) and, where; CuPc is copper phthalocyanine; M is a cation; x e y each independently has a value from 0.5 to 3.5; y (x + y) = 2 to 5; This process comprises: (i) chlorosulfonate a copper phthalocyanine compound using a chlorosulfonation agent; and (ii) condensing the product of step (i) with ammonia to give a mixture of copper phthalocyanine dyes of Formula (1); (iii) optionally exchanging the cation M in the copper phthalocyanine dye mixture of Formula (1) resulting from step (ii) for an alternative cation M; wherein the chlorosulfonation agent comprising a mixture of chlorosulfonic acid and a chlorinating agent selected from phosphorus oxychloride and phosphorus trichloride. Dyes can also be obtained through this process; the compositions and inks comprising these dyes; printed materials with these dyes, compositions or inks; inkjet printing cartridges containing inks made from dyes; and the inkjet printing machines comprising these cartridges. |
