A method of making microcapsule particles comprising an oil phase core material and a non-anionic wall material at least partially surrounding the core material said method comprising reacting a first, oil phase composition in the presence of a second, water phase composition, characterized in that: the first composition comprises a reaction product of the following components as an oil phase i) an amine acrylate or methacrylate dissolved or dispersed in said oil phase, ii) a multifunctional acrylate or methacrylate monomer or oligomer dissolved or dispersed in said oil phase, and iii) an acid dissolved in said oil phase and iv) an initiator in said oil phase, said first, oil phase composition being prepared by bringing the temperature of the oil phase to a wall pre-reaction temperature, mixing with high shear agitation to disperse the droplets, increasing the temperature to create a first composition reaction product, preparing a second oil phase, and combining and allowing the two oil solutions to pre-react by stirring and holding at the pre-reaction temperature for sufficient time to pre-react the wall material, wherein, after the pre-reaction step, the second, water phase composition is added to the first, oil phase composition, wherein the soluble acid and the amine acrylate are in a molar proportion from 3:1 to 1:3 and together have a percent by weight as compared to the weight of the wall material of from 0.1 to 20%, the second composition comprises a non-anionic emulsifier dissolved or dispersed in said water phase composition in an amount of from 0.1 % to 40% by weight of all constituents, at a pH from 4 to 10, and optionally a water phase initiator, whereby the reaction product of the first composition and second composition results in the formation of said microcapsules having a non-anionic microcapsule wall material of low permeance to the core material and having a zeta potential of -5 millivolts or greater, the resulting microcapsules having adherence to anionic surfaces. the first composition comprises a reaction product of the following components as an oil phase i) an amine acrylate or methacrylate dissolved or dispersed in said oil phase, ii) a multifunctional acrylate or methacrylate monomer or oligomer dissolved or dispersed in said oil phase, and iii) an acid dissolved in said oil phase and iv) an initiator in said oil phase, said first, oil phase composition being prepared by bringing the temperature of the oil phase to a wall pre-reaction temperature, mixing with high shear agitation to disperse the droplets, increasing the temperature to create a first composition reaction product, preparing a second oil phase, and combining and allowing the two oil solutions to pre-react by stirring and holding at the pre-reaction temperature for sufficient time to pre-react the wall material, wherein, after the pre-reaction step, the second, water phase composition is added to the first, oil phase composition, bringing the temperature of the oil phase to a wall pre-reaction temperature, mixing with high shear agitation to disperse the droplets, increasing the temperature to create a first composition reaction product, preparing a second oil phase, and combining and allowing the two oil solutions to pre-react by stirring and holding at the pre-reaction temperature for sufficient time to pre-react the wall material, wherein, after the pre-reaction step, the second, water phase composition is added to the first, oil phase composition, wherein the soluble acid and the amine acrylate are in a molar proportion from 3:1 to 1:3 and together have a percent by weight as compared to the weight of the wall material of from 0.1 to 20%, the second composition comprises a non-anionic emulsifier dissolved or dispersed in said water phase composition in an amount of from 0.1 % to 40% by weight of all constituents, at a pH from 4 to 10, and optionally a water phase initiator, whereby the reaction product of the first composition and second composition results in the formation of said microcapsules having a non-anionic microcapsule wall material of low permeance to the core material and having a zeta potential of -5 millivolts or greater, the resulting microcapsules having adherence to anionic surfaces.
