PRESSURE-SENSITIVE ADHESIVE COMPOSITION AND PRESSURE-SENSITIVE ADHESIVE SHEETS MADE THEREFROM, AND SEALANTS, REINFORCING SHEETS AND PRESSURE-SENSITIVE ADHESIVE SHEETS FOR PRINTING PRODUCED THEREFROM

摘要

A pressure-sensitive adhesive composition, wherein the storage elastic modulus ÄG'Ü at room temperature is at least 2 x 10<6> dyne/cm<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 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.
