Crosslinker-accelerator system for thermally crosslinking polyacrylates having functional groups, which are suitable for reacting with epoxy groups in a crosslinking reaction, comprises at least one compound containing at least one epoxy group, and at least one amine derivative (I). Crosslinker-accelerator system for thermally crosslinking polyacrylates having functional groups, which are suitable for reacting with epoxy groups in a crosslinking reaction, comprises at least one compound containing at least one epoxy group, and at least one amine derivative of formula ((R1) 2N-CR2R3-CR4R5-(CR6R7) n-X) (I). Either R1 : 1-8C alkyl or 1-8C cycloalkyl (both optionally substituted) or H; or R1+N : 5-7-membered ring (containing at least 4C and up to 1 further hetero atom); either R2-R7 : H or 1-8C alkyl; or R2+R3+R4+R5+R6+R7 : 5-7-membered cycloalkylene; n : 0-4; X : -OH, -OR, -SH, -SR or -PR2; and R : 1-18C alkyl (optionally branched and optionally substituted), 2-18C alkenyl, 2-18C alkynyl, aryl (optionally substituted) or aliphatic or aromatic heterocyclyl. Independent claims are also included for: (1) a thermally crosslinkable composition comprising at least one polyacrylate having functional groups, which are suitable for reacting with epoxy groups in a crosslinking reaction, and the above crosslinker-accelerator system; (2) a crosslinked polyacrylate obtainable by thermally crosslinking the above composition; and (3) thermally crosslinking the polyacrylates using the above crosslinker-accelerator system.
