GENTLE BLEACHING AGENT

摘要

The aim of the invention is to reduce the damage to cellulosic material during the bleaching treatment of cellulosic material by using catalysts with bleaching activity, without significantly impacting the bleaching performance in the process. This was achieved largely by way of a method for bleaching cellulosic material in the presence of a peroxygen-containing bleaching agent and a bleach-boosting transition metal complex, which is carried out in the presence of spherical polyelectrolyte brushes. The spherical polyelectrolyte brushes preferably contain the transition metal complex in a colloidally bound manner.
