摘要：A process for preparing a mixture of copper phthalocyanine dyes of Formula(1): CuPc(SO3M)x(SO2NH2)y, wherein: CuPc is copper phthalocyanine; M is a cation; x and yeach independently have a value of from 0.5 to 3.5; and (x+y) = 2 to 5; which processcomprises: (vii) chlorosulphonating a copper phthalocyanine compound using achlorosulphonating agent; and (viii) condensing the product of step (i) with ammonia togive a mixture of copper phthalocyanine dyes of Formula (1); (ix) optionally exchangingthe cation M in the mixture of copper phthalocyanine dyes of Formula (1) resulting fromstep (ii) for an alternative cation M; wherein the chlorosulphonating agent comprises amixture of chlorosulphonic acid and a chlorinating agent selected from phosphorousoxychloride and phosphorous trichloride. Also the dyes obtainable from this process;compositions and inks comprising these dyes; materials printed with these dyes,compositions or inks; ink-jet printer cartridges containing inks made from the dyes; andink-jet printers comprising these cartridges.
