    • The invention relates to a curing component (A) containing active CH groups, which contains at least two groups of the formula (I) ##STR1## or structural units of the formula (I') or (I") ##STR2## in which: A denotes ##STR3## X and Y are identical or different and denote ##STR4## CO.sub.2 R.sup.1, CN, NO.sub.2, CONH.sub.2, CONR.sup.1 H or CONR.sup.1 R.sup.1, where the R.sup.1 radicals may be identical or different and represent a hydrocarbon radical, preferably an alkyl radical having 1 to 12 carbon atoms, which may also be interrupted by oxygen or an N-alkyl radical, with the proviso that only one of the two radicals X and Y may represent the NO.sub.2 group;A' denotes ##STR5## X' and Y' are identical or different and denote ##STR6## Curable mixtures of (A) and a Michael acceptor (B) and, if appropriate diluents and customary additivies cure rapidly even at low temperatures and are suitable, in particular for surface-coating preparations.
    • 本发明涉及含有活性CH基团的固化组分(A),其含有至少两个式(I)的基团(I)或式(I')或(I“)的结构单元, (I')(I')其中:A表示X和Y相同或不同,表示CO 2 R 1,CN,NO 2,CONH 2,CONR 1 H或CONR 1 R 1,其中R 1基团 可以相同或不同,表示烃基,优选具有1至12个碳原子的烷基,其也可被氧或N-烷基中断,条件是两个基团X和Y中只有一个可以 代表NO2组; A'表示 X'和Y'相同或不同,表示(IMA)>(A)和迈克尔受体(B)的可固化混合物,如果合适,稀释剂和常规添加剂即使在低温下也能快速固化, ,特别是表面涂层制剂。
