Abstract
An adhesive composition comprising a) a tackifying resin, b) a styrene-isoprene-styrene block copolymer or a styrene-isoprene block copolymer with styrene blocks as the end blocks and having at least one internal block of an acrylic monomer, and c) a block copolymer of at least one vinyl aromatic hydrocarbon, at least one conjugated diolefin and at least one acrylic monomer, such as an alkyl methacrylate, which is on the end of the copolymer and is attached to a conjugated diolefin block.
