An aqueous emulsion composition that has high adhesion strength for a variety of materials so that it can be used for the adhesive bonding of even molded products and an adherent composition containing the aqueous emulsion composition. The aqueous emulsion composition comprises a carboxyl modified resin of a saponified ethylene-vinyl acetate copolymer and a surface active agent. This aqueous emulsion composition can be suitably used as adherent composition, such as an primer and an adhesive, for adhesive bonding a variety of molded products, such as plastic films, plastic sheets, plastic foams, fibers, synthetic leathers and metals. Due to the aqueous composition, the composition can have little risk to catch fire and can provide good sanitation in the environment.
An aqueous emulsion composition, comprising a carboxyl modified resin of a saponified ethylene-vinyl acetate copolymer and a surface active agent, which aqueous emulsion composition is produced by partly saponifying an ethylene-vinyl acetate copolymer, modifying the copolymer with an acid to produce the carboxyl modified resin of the saponified ethylene-vinyl acetate copolymer, and then mixing the carboxyl modified resin of the saponified ethylene-vinyl acetate copolymer with a surface active agent and water, thereby to emulsify the mixture, to obtain the aqueous emulsion composition.
