Abstract

En fremgangsmåte for behandling av papir omfatter påforing på papiret av enten en kationisk harpiks. PAE, eller av en latcx inneholdende funksjonelle syrcgruppcr idel haqiikscn og lalcxcn bringes pfi samtidig men separat, eller av en stabil blanding fremstilt på forhand inneholdende PAE og en latcx stabilisert med en ikkc-ionisk surfaktant.A method of treating paper involves applying to the paper either a cationic resin. PAE, or of a latcx containing functional acid groups both halic and lalcxcn, is taken at the same time but separately, or of a stable mixture prepared in advance containing PAE and a latcx stabilized with a nonionic surfactant.
