PURPOSE:To obtain titled paste with high adhesivity, capable of preventing optical distortion and surface roughening at folded part, for application to synthetic resins, by incorporating polyvinyl acetate partially-saponified product aqueous solution with acrylic emulsion, surfactant and boron compound in specific proportion. CONSTITUTION:The objective paste can be obtained by incorporating (A) an aqueous solution containing 3-15wt% of polyvinyl acetate partially saponified product with (B) 1-200wt% based on the solid content of the component (A) of acrylic emulsion (e.g. a product prepared by emulsion polymerization between 2-ethylhexyl acrylate and a monomer mixture containing, as comonomer, vinyl acetate), (C) 1-30wt% of surfactant (e.g. at least one sort of such agent selected from fatty acid sodium salts and combinations of them with higher alcohols) and (D) 0.01-20wt% of boron compound (e.g. boric acid). The other objective synthetic resin molded article can be obtained by using the above paste for laminating protective sheet on a synthetic resin plate.
