摘要：
A pressure-sensitive adhesive composition, wherein the storage elastic modulus [G′] at room temperature is at least 2×106 dyne/cm2 and the adhesive strength at room temperature is 1 kg/20 mm width or higher. Preferably, a pressure-sensitive adhesive composition comprising a polymer having a polycarbonate structure having a repeating unit represented by the following formula wherein R represents a straight chain or branched hydrocarbon group having from 2 to 20 carbon atoms, a pressure-sensitive adhesive sheet, a sealing material, a reinforcing sheet, and a pressure-sensitive sheet for printing, each having the pressure-sensitive adhesive composition.
