Abstract
A pressure-sensitive adhesive composition, wherein the storage elastic modulus [G'] at room temperature is at least 2.times.10.sup.6 dyne/cm.sup.2 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 ##STR1## 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.
