    摘要: Waterborne coating compositions are disclosed that include a latex emulsion polymer, and, as a coalescent, a levulinic acid ester of a monohydric aliphatic alcohol having from 10 to 20 carbon atoms. The coating compositions of the invention have a reduced VOC content, and provide improved coalescing activity compared with esters of polyols such as glycerol.

    摘要: Self-crosslinking aqueous coating compositions are disclosed comprising a water-dispersible alkyd having both sulfonate and acetoacetate functionality, a suitable bi- or poly-functional primary amine, and a monofunctional primary or cycloaliphatic secondary amine. The crosslinking of the composition includes oxidative curing via the fatty acid segments of the alkyd, and crosslinking via reaction between the acetoacetate groups of the alkyd and the primary amine groups of the polyfunctional amine. The aqueous alkyd systems disclosed do not require the presence of amines for the purpose of dispersing the alkyds, while exhibiting superior tack-free and through-dry times when used in coating compositions. Performance levels are achieved that heretofore had required increases in molecular weight and Tg, with a concomitant increase in VOC levels. Also disclosed are methods of making the inventive compositions.

    摘要: Disclosed is pigmented dispersion containing a non-amine wetting and dispersing agent and a water-dissipatable or dispersible polyester containing sulfonate groups that has improved stability having a substantial number of capped carboxyl groups attached to the sulfomonomer moieties. This polyester can be prepared by capping the carboxyl end groups of the polyester with oxirane compounds or by polymerizing the reactants wherein one reactant is a diol that is a diester adduct of a glycol and a dicarboxylic acid sulfomonomer.
