Abstract:
1. A surface treated article having a recoatable surface treatment that imparts stain an dirt pickup resistance to the treated surface and does not change the appearance of the treated surface comprising: a painted or coated article or an elastomer film surface treated with a surface treatment of one or more dispersion or emulsion of an aqueous acrylic or vinyl polymer consisting essentially of the polymerization product of, (ii) 53 wt. % or more of one or more non-ionic acrylic and/or vinyl comonomer having a solubility in water of less than 5 g/100 g of water at 25 ° C., based on the total weight of polymerized monomers, and (i) an ethylenically unsaturated (poly)carboxylic acid monomer in the amount of from 0 to 47 wt. %, the polymer having a glass transition temperature (Tg) of −10° C. or higher, and a number average molecular weight (Mn) of from 1,000 to 100,000, wherein the article comprises the surface treatment in the amount of 0.003 to 2 g of dry polymer per square meter of treated area (g/m
