Abstract
This invention relates to curable strippable adhesive and coating films, and also to improved high performance pressure sensitive adhesives. The adhesive comprises: (a) from 10 to 90 percent by weight of a crosslinkable epoxidized diene polymer, (b) from 0 to 70 percent by weight of a diene mono-ol polymer, with the condition that the mono-ol polymer not exceed three times the weight of the epoxidized polymer, (c) from 5 to 40 weight percent of a block copolymer of a vinyl aromatic hydrocarbon and a diene having, on average, more than one vinyl aromatic hydrocarbon block per molecule, and wherein the block copolymer can be functionalized by grafting onto it from 0.1 to 5% by weight of a carboxylic acid or anhydride, preferably maleic anhydride, (d) from 0 to 65% percent by weight of a tackifying resin, and (e) from 0.01 to 3 percent by weight of a photoinitiator.
