Patent ID: 7651765

Claim:
An adhesive composition for tapes, labels and bandages to be used at temperatures of +5° C. and lower, said adhesive composition comprising (a) at least one block copolymer, comprising at least two terminal blocks of poly(vinyl aromatic compound) and at least one midblock of a randomly copolymerized mixture of isoprene and butadiene, wherein the weight ratio between isoprene and butadiene is in the range of from 70:30 to 30:70, optionally mixed with a diblock copolymer comprising one poly(vinyl aromatic compound) block and one randomly copolymerized mixture of isoprene and butadiene, and optionally mixed with a block copolymer, comprising at least one block of poly(vinyl aromatic compound) and at least one block of poly(butadiene) or poly(isoprene), (b) at least one mixed aliphatic/aromatic tackifying resin or a blend of aliphatic and aromatic tackifying resins, having an aromatic H-NMR content between 6 and 22%, wherein the tackifying resin has a glass transition temperature Tg between 30° C. and 40° C., and a Ring and Ball softening point between 80° C. and 90° C., and (c) a plasticizer in an amount of at most 25 wt %, relative to the weight of the adhesive composition.
