摘要： A system and method for rupturing an encapsulated adhesive in a, sheet media (12) uses an activator unit (24). This unit can include one or more of the following: a pressure roller (52), a pair of pressure rollers (26), an activator blade (28), a set of rotatable discs (66) or a series of sets of rotatable discs. A sheet media having an encapsulated adhesive is fed past the activator unit in the system and method whereby the capsules will be ruptured. A feeder (22), label printer (16), cutter (36) and label applicator (38) can also be provided m this system.

摘要： A novel adhesive formed in situ in a microcapsule and method for forming such a pressure sensitive or flowable adhesive in situ in a microcapsule is disclosed. The method for forming the novel adhesive comprises providing an aqueous mixture of wall material in water; adding a substantially water insoluble core material, free radical initiator, and a solvent for the pre-polymers to the aqueous mixture. The core material comprises a first addition polymerizable pre-polymer having a Tg of less than about 0° C., a flash point of at least 75° C., and a boiling point of at least 175° C. These are typically selected from acrylate or methacrylate type materials. Optionally included is a second addition polymerizable pre-polymer for providing cross-linking or interaction between polymer chains. High shear agitation is provided to the aqueous mixture to achieve a particle size of about 0.1 to 250 microns. Stirring at a first temperature effects capsule wall formation; and heating to a second temperature polymerizes the pre-polymers of the core material to form an adhesive in situ in the formed capsules.

摘要： The present invention teaches a cationically charged or neutral microcapsule particle comprising an oil soluble or dispersible core material and a wall material at least partially surrounding the core material, the microcapsule wall material comprising the reaction product of a first composition in the presence of a second composition comprising an emulsifier which is cationic or nonionic, the first composition comprising a reaction product of i) an oil soluble or dispersible amine with ii) a multifunctional acrylate or methacrylate monomer or oligomer, an oil soluble acid and an initiator. The cationic or nonionic emulsifier comprises a water soluble or water dispersible material and optionally a water phase initiator. The first composition initiator and the water phase initiator is an energy-activated initiator. The reaction product of the first composition and second composition results in the formation of a population of microcapsules having a microcapsule wall of low permeance to the core material and having a zeta potential of - 5 millivolts or greater. The resulting microcapsules have adherence to anionic surfaces.

摘要： Dual shell microcapsule aggregate particles and copy materials coated therewith, such aggregate particles having inner shells surrounding chromogenic nucleus material, and outer shells encompassing multiple such inner shells to form aggregate particles thereof. The inner shells are derived from polar pre-polymer compositions. The outer shells are derived from complex colloids such as gelatin and gelatin derivatives. The outer shell material causes agglomeration of the inner shells into aggregate particles, thus increasing the sizes of the particles without increasing the sizes of the respective inner-shell microcapsules which contain the chromogenic material.
