Zusammenfassung:A pressure-sensitive adhesive copolymer material formed from (A) 50-80 percent by weight of at least one diester of fumaric acid and a saturated monovalent aliphatic alcohol containing from 3 to 12 carbon atoms, (B) 18-40 percent by weight of at least one vinyl compound copolymerizable with (A) and (C) from 0.5 to 15 percent of at least one monoolefinic polar compound copolymerizable with (A) and (B) having a polar group from carboxyl, carboxamide, dicarboxylic acid anhydride and dicarboximide; or from (A), (B) and (D) from 0.1 to 10 percent by weight of at least one monoolefinic compound copolymerizable with (A) and (B) having self cross-linkable groups from hydroxy, epoxy, N-methylolamide, aldehyde and isocyanate groups; or from (A), (B), (C) and (D) and which contains from 0.1 to 10 percent by weight of the copolymers of a crosslinking active polyfunctional compound for copolymers of the foregoing components in at least a partially cross-linked state.
