Title
(EN) REDUCTION OF BLEEDING OF LIGNOSULFONATES FROM TREATED SUBSTRATES
(FR) REDUCTION DE LA MIGRATION DE LIGNOSULFONATES SUR DES SUBSTRATS TRAITES
Abstract
(EN) The bleeding of lignosulfonates from lignosulfonate-treated substrates when contacted under humid conditions is reduced by rendering the lignosulfonated water-insoluble via reacting them with an amine polymer-epichlorohydrin adduct containing at least one quaternary ammonium group under acidic conditions.
(FR) Selon l'invention, il est possible de réduire la migration de lignosulfonates sur des substrats traités aux lignosulfonates, lorsqu'ils se trouvent dans des conditions humides, en rendant ces lignosulfonates insolubles dans l'eau par leur mise en réaction avec un adduit d'épichlorhydrine-polymère aminé contenant au moins un groupe ammonium quaternaire dans des conditions acides.
