Abstract: The present invention is a composition comprising a solution or a dispersion of polymer particles, a sorbate ester or sorbamide curing agent, and a cure modulating additive for the curing agent. The curing agent is a sorbic acid ester or a sorbamide and the cure modulating agent is a reagent capable of accelerating or attenuating the rate of cure of the curing agent. The control of cure kinetics is important for speeding up cure rates where rates are too slow or by reducing cure rates where curing too rapidly results in undesirable color formation.

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.
