An aqueous leather coating composition having improved storage stability, a method of coating leather with the composition, and a coated leather article. An emulsifiable polyisocyanate containing 1 to 40 weight percent of a reaction product of a trimer of hexamethylene diisocyanate and an emulsifier, wherein the average isocyanate functionality of the emulsifiable polyisocyanate is 2 to 4.5 and − has a T g of 70 to 40 ° C., and (meth) acrylic polymer dispersion, selected polyurethane dispersion, a combination comprising one or more (meth) acrylic polymer / polyurethane hybrid dispersion and the aforementioned aqueous polymer dispersion 60 to 99 weight percent of the aqueous polymer dispersion, all weight percents are on a dry basis and are based on the total dry weight of the emulsifying polyisocyanate and the aqueous polymer dispersion. The aqueous polymer dispersion may not contain hydroxyl groups. [Selection figure] None |
