• the improvement comprises said curing accelerator being a compound of the formula ##STR9## wherein R.sup.1 to R.sup.3 represent hydrogen, C.sub.1 -C.sub.18 -alkyl, C.sub.5 -C.sub.8 -cycloalkyl, C.sub.6 -C.sub.14 -aryl or halogen,
• R.sup.4 represents hydrogen, C.sub.1 -C.sub.18 -alkyl or C.sub.5 -C.sub.8 -cycloalkyl,
• R.sup.5 represents C.sub.1 -C.sub.18 -alkylene, C.sub.5 -C.sub.8 -cycloalkylene or C.sub.6 -C.sub.14 -arylene,
• R.sup.6 represents hydrogen or C.sub.1 -C.sub.4 -alkyl and
• R.sup.7 represents hydrogen, a saturated or unsaturated hydrocarbon radical having 1-18 carbon atoms, a hydroxy-substituted saturated or unsaturated hydrocarbon radical having 1 to 18 carbon atoms, or the radical ##STR10## wherein R.sup.4, R.sup.5 and R.sup.6 are as defined above.
