Patent ID: 7872065

Claim:
An adhesive composition comprising, i. at least one block copolymer (i)(a) of the formula A-I-A or (A-1)nX, and a diblock copolymer (i)(b) of the formula A-(I/B), wherein each A is independently a polymer block of an aromatic vinyl compound, each I is a poly(isoprene) polymer block, (I/B) is a mixed random polymer block of isoprene and butadiene in a weight ratio of I:B of from 20:80 to 80:20, n is an integer equal to or greater than 2 and X is the residue of a coupling agent, and wherein the weight ratio between said block copolymers (i)(a) and (i)(b) is such that the overall butadiene content in component (i) is from 0 to less than 12 wt %, ii. a tackifying resin selected from C5 hydrocarbon resins, and iii. one or more plasticizers.
