摘要： The invention provides an adhesive composition which is prepared by compounding a calcium silicate alone or a combination thereof with an isocyanate in a vinyl acetate polymer emulsion containing acetoacetylated polyvinyl alcohol as a protective colloid. This composition solves the problems with conventional adhesives obtained by compounding an isocyanate or the like in an emulsion, and shows a long-lasting adhesion strength, undergoes less reduction in, particularly, initial adhesion strength, and shows better water resistance (water-resistant adhesion) and heat resistance (heat-resistant adhesion) than those of conventional compositions.
