    摘要： An aqueous composition suitable for use, when dry, as an improved coating is provided including an aqueous emulsion polymer, the polymer having a glass transition temperature (Tg) from greater than 20 °C to 80 °C, formed by the free radical polymerization of at least one ethylenically unsaturated nonionic acrylic monomer and 0-7.5%, by weight based on the total weight of the polymer, ethylenically unsaturated acid monomer in the presence of 0.01-1.0%, by weight based on the total weight of the polymer, t-alkyl hydroperoxide, t-alkyl peroxide, or t-alkyl perester wherein the t-alkyl group includes at least 5 Carbon atoms and, optionally, at least one other oxidant. A method of preparing the emulsion polymer, a method for providing a coated substrate wherein the coating contains the emulsion polymer having a Tg from -20 °C to 80 °C, and a method for improving the scrub resistance of a coating by including the emulsion polymer having a Tg from -20 °C to 80 °C are also provided.

    摘要： An aqueous-based, UV radiation-curable coating composition containing a latex polymer emulsion and a multifunctional (meth)acrylate, wherein the latex polymer is selected to be greater than about 47 mole % acrylate and to have a glass transition temperature less than about 28°C is described. The selection of composition and glass transition temperature yields a UV-curable coating with superior direct impact properties which are useful for wood coating applications.
