US 2017/0253776 A1 · WATER-BASED COMPOSITION

Abstract

An object of the present invention is to provide a pressure-sensitive adhesive having excellent adhesive property, facilitating secondary processing of an adhesive product and providing an adhesive product with excellent holding strength to a substrate and adhesion property to a curved surface. The present invention relates to a water-based composition comprising: (A) an aqueous resin emulsion comprising a polymer having a glass transition temperature of −65 to −40° C. and (B) an aqueous resin emulsion comprising a polymer having a glass transition temperature of 20° C. or more, wherein the aqueous resin emulsion has a minimum film-forming temperature of 40° C. or more.
