| 摘要 |
<p>The invention is concerned with an aqueous filmforming binder dispersion or emulsion containing (a) an unsaturated polyester resin having an acid number between 1 and 50, an OH number between 10 and 120 and a mean molecular weight between 300 and 5,000, and (b) an acrylate polymer produced from esters of methacrylic acid or acrylic acid with lower aliphatic alcohols having 1 to 3 carbon atoms or mixtures thereof with other copolymerizable monomers selected from the group consisting of styrene, vinyltoluene and methacrylic acid, the acrylate polymer having a film-forming temperature of above 60.degree.C. The aqueous dispersion or emulsion of the invention is particularly useful for the production of fast-setting coatings on the surfaces of various materials.</p> |
