Abstract: The present invention is a composition comprising a stable aqueous dispersion of polymer particles and a sorbate ester, which is a liquid at 20° C. and has a molecular weight in the range of 125 to 500 g/mol. The composition of the present invention provides a way to enhance film formation of coatings prepared using relatively high Tg latexes without the aid of high volatile organic content (VOC) coalescents.

Abstract: In an aspect, a composition comprises an alkali-swellable copolymer that is derived from a mixture comprising 15 to 50 wt % of an ethylenically unsaturated carboxylic acid; 30 to 70 wt % of an ethylenically unsaturated C1-2 alkyl carboxylate ester; and 15 to 40 wt of a nonionic ethylenically unsaturated surfactant monomer of the Formula (A); and less than or equal to 0.15 wt of a multifunctional monomer contains greater than 1 vinyl group. The composition has a pH of greater than or equal to 6. The composition can optionally comprise a surfactant.

Abstract: A process for adjusting the wettability property of a plurality of on-demand activation-type microcapsules of a core and shell structure including the steps of: (a) providing a plurality of microcapsules of a core and shell structure, wherein the shell includes a polymeric matrix containing a certain amount of unreacted functionalizable reactive electrophiles covalently bonded to the surface of the wall of the shell of the microcapsules; and (b) contacting the plurality of microcapsules of step (a) with a certain amount of nucleophiles; wherein the nucleophiles are adapted to react with the electrophiles; and wherein the nucleophiles are adapted to modify the wettability property of the microcapsules' shell structure to a predetermined degree of hydrophilicity or solvent compatibility.
