The present invention provides a thermosetting pressure sensitive adhesive composition comprising, based on the total weight of the composition, the following components: a) a glass transition temperature Tg of from -35 占 폚 to 32 占 폚, From 35 to 99% by weight of a reactive polymethacrylate component having a reactive functional group capable of forming a polymer network; And b) from 1 to 65% by weight of a benzoxazine component of the formula: In this formula, X is a covalent bond, C 1 -C 6 alkylene, C 3 -C 10 cycloalkylene group, , C = O, S, S = O or O = S = O, R 1 and R 2 are the same or different and are independently selected from the group consisting of hydrogen, C 1 -C 6 alkyl, or C 5 -C 14 aryl, R4 is selected from the group consisting of hydrogen, halogen or C 1 -C 6 alkyl. The present invention also provides an adhesive tape comprising an electrically conductive adhesive composition and a composition as described above and provides the use of the composition for making films used in electronic and electrical products, automotive products and new energy installations. |
