Patent ID: 7560512

Claim:
An adhesive composition comprising, i. at least one block copolymer (i)(a) of the formula A-I-A (1) or (A-I) n X (2), and at least one block copolymer (i)(b) of the formula A-(I/B)-A (3) or [A-(I/B)] n -X (4), wherein each A is independently a polymer block of an aromatic vinyl compound, each I is a poly(isoprene) polymer block, each (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 less than 20 wt %, ii. a single tackifying resin selected from modified aliphatic hydrocarbon resins that are not aromatic modified, and iii. one or more plasticizers.
