To provide an aqueous emulsion composition which has high adhesion strength for a wide variety of materials including molded products and affords sufficient wettability even for the object to be adhesive bonded of low surface polarity so that it can develop sufficient adhesiveness and whose emulsion is stable so satisfactorily as to provide good mechanical stability and storage stability, and to provide an adherent composition comprising the aqueous emulsion composition, at least ethylene-vinyl acetate copolymer or modified resin thereof, photo polymerization initiator, and unsaturated ethylenic monomer are mixed and dissolved or dispersed, to prepare oil drop component, followed by emulsifying the oil drop component in water by using a surface-active agent, whereby an aqueous emulsion composition, in which micelles each encapsulating at least the ethylene-vinyl acetate copolymer or modified resin thereof, the photo polymerization initiator and unsaturated ethylenic monomer are dispersed in water, is prepared.
An aqueous emulsion composition wherein micelles each encapsulating an ethylene-vinyl acetate copolymer or a modified resin thereof, a photo polymerization initiator and an unsaturated ethylenic monomer are dispersed in water, which is produced by a process wherein at least the ethylene-vinyl acetate copolymer or modified resin thereof, the photo polymerization initiator, and the unsaturated ethylenic monomer are mixed and dissolved or dispersed, to prepare an oil drop component, followed by emulsifying the oil drop component in water by using a surface-active agent.
An adherent composition comprising an aqueous emulsion composition wherein micelles each encapsulating an ethylene-vinyl acetate copolymer or a modified resin thereof, a photo polymerization initiator and an unsaturated ethylenic monomer are dispersed in water, which is produced by a process wherein at least the ethylene-vinyl acetate copolymer or modified resin thereof, the photo polymerization initiator, and the unsaturated ethylenic monomer are mixed and dissolved or dispersed, to prepare an oil drop component, followed by emulsifying the oil drop component in water by using a surface-active agent.
