Process for treating stained fabrics with manganese phthalocyanines

摘要

A substituted phthalocyanine in which at least one of the peripheral carbon atoms in the 1-16 positions of the phthalocyanine nucleus (MnPc) as shown in Formula (1) <IMAGE> Formula (1) is linked via an oxygen atom or a sulphur atom to an organic radical, the remaining peripheral carbon atoms being unsubstituted or substituted by any combination of atoms or groups and sulphonated derivatives thereof. Compositions comprising one or more compounds of Formula (1) and their use as cleaning materials are also disclosed along with a process for removing stains and/or grime from fabrics using these
