    • The present invention teaches microcapsule particles comprising an oil soluble or dispersible core material; and a wall material at least partially surrounding the core material, the microcapsule wall material consisting of the reaction product of a first composition in the presence of a second composition; the first composition comprising a water phase: the water phase comprising a water soluble or dispersible initiator having at least one —COOH or amine functional group and a nonionic emulsifier, the emulsifier comprising a water soluble or dispersible material at a pH from 4 to 12, the water soluble or dispersible initiator is selected from initiators having a C—N═N—C type structure and of formulas I, II or III (set forth in the specification) having amine or carboxyl functionality.The second composition comprises an oil phase. The oil phase comprises: i) one or more multi functional acrylate or methacrylate monomers or oligomers and substantially free of amine acrylate or amine methacrylate monomer or oligomer, and an initiator dispersible in the oil phase; ii) from 0 to 10% by weight of the oil phase, of a monofunctional acrylate or methacrylate monomer or oligomer; iii) an intended core material; and iv) a diluent selected from esters of glycerol and fatty acids wherein at least one of the fatty acids is C12 or greater; wherein the ratio of the water phase initiator to multifunctional acrylate or methacrylate is from 0.1:99.9 to 20:80 by weight; wherein the ratio of the diluent to the core material is from 0.1:99.9 to 90:10 on a weight basis; and whereby the reaction product of the first composition and second composition results in the formation of a population of microcapsules.
