摘要
A stable aqueous polymeric composition is comprised of an aqueous anionic polyurethane dispersion and a compatible polymeric dispersion or emulsion the polymer being water insoluble. The compatible dispersions or emulsions may have a substantially neutral pH or be anionic or cationic. The polymeric compositions are useful in impregnating porous substrates to form composite sheet materials which can be further processed to form simulated leather and the like.
