Photobleach system, composition and process |
摘要 |
A photobleach system is disclosed comprising a synergistic mixture of an electron donor and a visible/ultraviolet radiation absorbing compound (a chromophore acceptor) which is capable of, in an excited electronic state, undergoing electron transfer from said electron donor. A composition comprising said photobleach system and use of the system or composition in bleaching dyes and textiles are also disclosed. A preferred electron donor is sodium sulphite. Preferred chromophore acceptors are water-soluble metallated phthalocyanines and naphtalocyanines.
