Druckempfindliche gegen Blasenbildung resistente Klebefolie.

摘要

The pressure sensitive adhesive sheet has excellent adhesive strength resistance against formation of blisters and removability on heating and after heating. The pressure sensitive adhesive sheet comprises a substrate and an adhesive composition which is coated on the surface of the substrate and comprises as the main component thereof a copolymer comprising monomeric units of an acrylic ester, monomeric units of a polar acrylic compound, monomeric units of a high glass transition temperature (Tg) macromonomer having a Tg of 20 DEG C or above, monomeric units of a low Tg macromonomer having a Tg of below 20 DEG C and, optionally, monomeric units of an oligomer having telechelic thiol functional groups.
