Abstract
Abstract Aqueous bleaching compositions can be satisfactorily coloured by inclusion therein of a coloured polymer latex which consists of a copolymer of a hydrophobic monomer with a reactive copolymerisable monomer containing a chromophore. These coloured polymer latices are particularly suitable for colouring hypochlorite-containing bleaching compositions.

Claim 1
Independent Claim
57 words
A coloured aqueous bleaching 4 gent comprising an oxygen or chlorine bleaching agent and a colouring agent in an aqueous medium, characterised in that the composition comprises from 0.0005-10% by weight of a colouring agent which is a coloured polymer latex consisting of a copolymer of a hydrophobic monomer with a reactive copolymerisable monomer containing a chromophore.
Claim 2
Dependent Claim
57 words
A coloured aqueous bleaching 4 gent comprising an oxygen or chlorine bleaching agent and a colouring agent in an aqueous medium, characterised in that the composition comprises from 0.0005-10% by weight of a colouring agent which is a coloured polymer latex consisting of a copolymer of a hydrophobic monomer with a reactive copolymerisable monomer containing a chromophore.
