The invention is a fibrous cellulosic product, containing a uniformly dispersed polymeric material which has been deposited in an aqueous suspension from an anionic latex, and the method for its manufacture. Cellulosic fiber is first cationized by treating it in an aqueous suspension with the condensation product of epichlorohydrin and dimethylamine. Up to 30% of the dimethylamine may be replaced with a crosslinking agent which can be ammonia or an aliphatic diamine such as hexamethylene diamine. The cationized fiber, with or without small quantities of alum, will effectively retain a wide variety of anionic latices when treated in an aqueous environment.

A cellulose based product which comprises: a. a fibrous cationic cellulose prepared by the treatment under aqueous alkaline conditions of cellulose with a material from the group consisting of a reaction product of epichlorohydrin and dimethylamine, said reaction product further modified with a crosslinking agent, and mixtures thereof wherein the crosslinking agent, if present, is selected from the group consisting of ammonia and a primary aliphatic diamine of the type H2N－R－NH2 where R is an alkylene radical of from 2 to 8 carbon atoms; and b. from 0.1 to 30%, on a dry weight basis, of a polymeric capable of being emulsified into an anionic dispersion, said polymer being uniformly dispersed on the fibrous cellulose.
