ABSTRACT:
A pressure sensitive adhesive sheet comprising a substrate and an adhesive composition which is coated on the surface of the substrate. The main components of the adhesive composition are (a) a copolymer comprising monomeric units of an acrylic ester, (b) monomeric units of a polar acrylic compound, (c) monomeric units of a high glass transition temperature (Tg) macromonomer having a Tg of 20.degree. C. or above, (d) monomeric units of a low Tg macromonomer having a Tg of below 20.degree. C. and (e) monomeric units of an oligomer having telechelic thiol functional groups. The pressure sensitive adhesive sheet has excellent adhesive strength, resistance against formation of blisters and removability upon heating.
