CA 2652855

The presence of both a water sizing agent and an oil sizing agent in a paper making furnish is detrimental in that each has an adverse effect on the sizing property of the other. It has now been found that this adverse effect can be counteracted or lessened by the presence in the furnish of a polyvinylamine.

Selon l'invention, la présence d'un agent de collage hydrofuge et d'un agent de collage oléofuge dans une composition de fabrication du papier est nuisible étant donné que chaque agent présente un effet indésirable sur la propriété de collage de l'autre. On a désormais découvert que cet effet indésirable peut être supprimé ou atténué par la présence d'une polyvinylamine dans la composition de fabrication.
