Crosslinker-accelerator system for the thermal crosslinking of polyacrylates having functional groups capable of entering into linking reactions with epoxide groups, comprising at least one substance having at least one epoxide group as crosslinker and at least one substance of the formula

description='In-line Formulae' end='lead'R¹₂N—CR²R³—CR⁴R⁵—(CR⁶R⁷)_n—Xdescription='In-line Formulae' end='tail'

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 is an integer from 0 to 4; andX 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.
