Abstract:
An aqueous composition suitable for use in coating leather comprising an aqueous emulsion polymer comprising from 0.1% to 6% by weight of copolymerized acetoacetate or acetoacetamide monomer based on the weight of said polymer and from 2% to 15% by weight of copolymerized carboxylic acid monomer based on the weight of said polymer and having a glass transition temperature (Tg) from -40.degree. C. to 0.degree. C.; said polymer having been contacted with a transition metal oxide, hydroxide, or carbonate at a pH of less than 9 in an amount greater than 0.20 equivalent of transition metal per equivalent of said copolymerized carboxylic acid monomer in said polymer.
