Abstract:
A method for providing a coated substrate comprising: forming an aqueous coating composition comprising an aqueous emulsion polymer, the polymer having a glass transition temperature (Tg) from âˆ’60Â° C. to 80Â° C., formed by the free radical polymerization of at least one ethylenically unsaturated nonionic acrylic monomer, 0.1-50%, by weight based on the total weight of said polymer, ethylenically unsaturated aldehyde reactive group-containing monomer, and 0-7.5%, by weight based on the total weight of said polymer, ethylenically unsaturated acid monomer in the presence of 0.01-1.0%, by weight based on the total weight of said 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;applying said aqueous coating composition to said substrate; and drying, or allowing to dry, said aqueous composition.
