The aim of the invention is reduce the damage to material containing cellulose during the bleaching thereof, by using bleaching catalysts, without significantly affecting the bleaching performance. This is achieved essentially by a method for the bleach treatment of material containing cellulose in the presence of a bleaching agent containing peroxygen and a bleach-enhancing transition metal complex, said method being carried out in the presence of a saccharide polymer carrying carboxy groups.
