To obtain a water-base adhesive compsn. which has an initial adhesiveness capable of withstanding the use in a dry adhesion method and has excellent normal-state adhesive power and heat resistance similar to those obtainable by a wet adhesion method by selecting a two-component adhesive compsn. comprising a specific main component and a curative.
This adhesive compsn. is prepd. by compounding 100 pts.wt. main component comprising an emulsion of a urethane resin having polyester backbones and polyether backbones and having acid groups and an emulsion of an ethylene-vinyl acetate copolymer having an ethylene content of 5-40wt.% and a toluene insolubles content (as a dried film) of 70wt.% or higher with 2-20 pts.wt. compd. having at least two acid-reactive groups as the curative. The urethane resin is pref. The one obtd. by reacting a compd. having a polyester backbone with a compd. having a polyether backbone in a wt. ratio of (20:80)-(60:40).
