An aqueous dispersion type pressure-sensitive adhesive composition which isnexcellent in adhesion to foams and unsusceptibility to edge peeling and retains stablenadhesive force over long, a pressure-sensitive adhesive sheet including a substrate and,ndisposed on one or both sides thereof, a pressure-sensitive adhesive layer comprisingnthe aqueous dispersion type pressure-sensitive adhesive composition, and anpressure-sensitive adhesive rubber foam sheet comprising a rubber foam and, disposednon one or both sides thereof, the pressure-sensitive adhesive layer or pressure-sensitivenadhesive sheet. The aqueous dispersion type pressure-sensitive adhesive compositionncomprises an aqueous dispersion of a polymer obtained by copolymerizing a monomernmixture comprising one or more alkyl (meth)acrylates as the main component and atnleast one silane monomer, and a tackifier having a phenolic skeleton, added to thenaqueous dispersion. |
