Abstract

La présente invention a pour objet de diminuer l'altération d'une matière cellulosique lorsqu'elle subit un traitement de blanchiment, par utilisation de catalyseurs à action blanchissante, sans qu'il y ait d'effet sensible sur l'efficacité du blanchiment. A cet effet, l'invention a trait essentiellement à un procédé de traitement de blanchiment de matière cellulosique en la présence d'un agent de blanchiment contenant des composés peroxygénés et d'un complexe de métal de transition renforçant le blanchiment, ledit procédé étant mis en oeuvre en la présence d'un polymère saccharidique portant des groupes carboxy.
