A synthetic leather is made by a impregnating a non-woven or woven textile with an aqueous polyurethane dispersion comprised of a nonionizable polyurethane and an external stabilizing surfactant. The impregnated textile is then exposed to water containing a coagulant for a coagulation time sufficient to coagulate the dispersion. The method may be used to form a synthetic leather having excellent wet ply adhesion and may contain an insoluble multivalent cation organic acid.
