An adhesive composition is provided comprising: (a) an A-B-A block copolymer with an A block that is non-elastomeric comprised of homopolymers and copolymers of vinyl monomers, and a B block that is elastomeric and is substantially hydrogenated, (b) a tackifying resin, and (c) optionally, a plasticizer in an amount of 20 % by weight or less, the A-B-A block copolymer being present in the composition in an amount ranging from 15-60 % by weight, and the tackifying resin being present in the composition in an amount ranging from 40-85 % by weight, each being based on the total weight of the composition, the block copolymer including a graft moiety in an amount within the range of from 0.5 to 5.0 % by weight, wherein the graft moiety is selected from the group consisting of ethylenically unsaturated carboxylic acids, ethylenically unsaturated carboxylic acid anhydrides, and derivatives thereof. |
