Cure on demand adhesives and window module with cure on demand adhesive thereon

An adhesive composition comprising

• a) a polymer having a reactive moiety capable of cross-linking,
• b) a particle comprising an active agent encapsulated in an encapsulating agent wherein the active agent comprises a catalyst for cross-linking of the reactive moiety, a curing agent for the reactive moiety, an accelerator for the curing reaction or a mixture thereof;
• and the encapsulating agent comprises crystallizable polymer wherein the active agent is soluble in the crystallizable polymer or does not volatilize at the temperature of the encapsulation process;
• wherein about 1 percent by weight or less of the active agent is extractable from the particle at ambient conditions during the first extraction after particle formation when the particles are contacted with a solvent for the active agent which solvent is not a solvent for the crystallizable polymer, and wherein the composition exhibits a tensile strength upon cure of about 250 psi or greater.
