PURPOSE:To provide the titled adhesive consisting of the first liquid composed of an ethylene-vinyl acetate copolymer emulsion and the second liquid composed of a polyisocyanate compound, suitable for the production of an elastic mat, the base of a TATAMI mat, etc. having high air permeability and water resistance, and available at a low cost. CONSTITUTION:The objective adhesive can be prepared by mixing (A) an ethylene-vinyl actate copolymer with (B) a polyisocyanate compound in the presence of a proper amount of water. The adhesive is applied to or mixed with an adhered and heated at 140-160 deg.C to obtain a bonded product. The sum of the solid content of the component A and the component B is preferably 40-60(wt)% of the mixture, and the content of water is preferably 60-40%. The weight ratio of the component B to the component A is preferably 0.3-0.6 to 1.
