Abstract (en)

[origin: EP0184888A2] The invention provides an aqueous, coloured bleaching composition, particularly a thickened chlorine bleaching composition, in which as colouring agent a colloidally stable, coated pigment is used which has been coated with a bleach-resistant polymer, e.g. polystyrene. These coated pigments are colloidally stable in the bleaching composition, in many cases more stable than uncoated pigments.
