摘要:
An aqueous coating composition including a) a composite particle including an opacifying pigment particle such as, for example, TiO2 and, disposed thereon, a plurality of particles of a first polymer, the first polymer being a select P-acid containing emulsion polymer and b) from 7% to 25% by weight, based on the total weight of polymer in the aqueous coating composition, of a select second polymer is provided. A method for forming the aqueous coating composition, a method for forming a dried coating therefrom, and the coating so formed are also provided.

摘要:
The present invention relates to a process for preparing a multistage phosphorus acid functionalized latex polymer comprising the steps of: a) contacting a first acrylic monomer with a first phosphorus acid monomer under emulsion polymerization conditions to form a first stage polymer; then b) contacting the first stage polymer with a second acrylic monomer and a second phosphorus acid monomer under emulsion polymerization conditions to form the latex polymer. The latex polymer is useful as an absorbing polymer for pigment particles used, for example, in coatings formulations.
摘要:
The present invention provides surface treated articles comprising a recoatable surface treatment of an acrylic or vinyl polymer that does not change the appearance of the treated surface, and which imparts blocking resistance and/or stain and dirt pickup resistance to the treated surface. The one or more acrylic or vinyl polymer has a number average molecular weight of from 1,000 to 100,000, a glass transition temperature of −10° C. or higher, preferably, 30° C. or higher, and comprises the polymerization product of one or more non-ionic monomer, such as methyl methacrylate, with up to 47 wt. % of an ethylenically unsaturated acid monomer and, preferably, is non-migrating under use conditions. When dry, the surface treatments may form a layer of domains of polymer distributed all over the treated surface, rather than a film. Treated articles include coating or painted articles and elastomer films.

Treated articles include coating or painted articles and elastomer films exhibiting blocking and stain resistance, and uncoated wood, glass, metal or plastic articles and laminates, such as countertops, exhibiting stain and dirt pickup resistance.
