    one substance having at least one epoxide group as crosslinker and
    at least one substance of the formula R12N—CR2R3—CR4R5—(CR6R7)n—X in which the R1 independently represent hydrogen, a substituted or unsubstituted alkyl or cycloalkyl radical or together with the nitrogen atom form a 5-7-membered ring; R2, R3, R4, R5, R6 and R7 independently represent hydrogen or an alkyl radical having 1 to 8 carbon atoms or form a 5-7-membered cycloalkylene group; n=0; and X represents —OH, —OR, —SH, —SR and —PR2, in which R independently represents C1-C18 alkyl radical, C2-C18 alkenyl radical or C2-C18 alkynyl radical, an aryl group or an aliphatic or aromatic heterocycle, as accelerator.

    Abstract: The invention provides meltable and UV-crosslinkable pressure-sensitive adhesives, such as acrylate hotmelts or hotmelt formulations, which can be processed by commonplace hotmelt processes and also on customary hotmelt coating lines, without any immediate alteration in the product properties in the event of (unwanted) deviation in the operational parameters. The compositions of the invention are UV-crosslinkable and meltable pressure-sensitive adhesives comprising (i) mixtures of UV-crosslinkable polyacrylate polymers selected from a) mixtures of UV-crosslinkable polymers with at least one photoinitiator bonded covalently to the backbone of the polymers, and b) mixtures of UV-crosslinkable polyacrylate polymers, monomers and at least one photoinitiator, and also (ii) at least one UV stabilizer, and also methods for producing them and the use thereof as bonding agents.

    Abstract: In the context of a polyacrylate-based composition, the intention is to allow controlled thermal crosslinking. This is accomplished by provision of a crosslinker-accelerator system for the thermal crosslinking of polyacrylates having functional groups suitable for entering into linking reactions with epoxide groups, comprisingat least one substance comprising at least one epoxide group (crosslinker) and at least one substance conforming to the general formula (I) NR3  (I), in which the radicals R independently of one another are a hydrogen atom or an organic radical having 1 to 20 carbon atoms, with at least one of the radicals R being an organic radical with 1 to 20 carbon atoms, and comprising at least one alcoholic OH group.
