For this research, prepared water soluble milk casein resin and waterborne polyurethane-acrylic resin. Use these resin, this article has been analyzed about change of mechanical properties by increasing amount of casein resin in polyurethane-acrylic resin on coated leather. According to measure data for solvent resistance, WPA(waterborne polyurethane-acrylic resin) resin and WPA-C1, C2, C3(samples of polyurethane-acrylic resin with milk casein resin) had good property. As known in the results, increase of casein constant did not influence to big change of hybrid resin properties. As test of tensile strength, WPA had lowest tensile characteristic(1.598 $kg_f/mm^2$) and WPA-C3 had highest tensile characteristic(1.718 $kg_f/mm^2$). Also best properties of abrasion was WPA-C3(06.021 mg.loss). In elongation case, WPA had best properties(754 %) in this experiment.
