Abstract

A reaction product of (A) compounds containing at least two R.sup.1 R.sup.2; C.dbd.CR.sup.3 --X groups (I) with (B) compounds which contain PA1 (a) at least two active H atoms or PA1 (b) at least two groups containing active H atoms of the type --AH-- (II) or PA1 (c) at least one active H atom and at least one group of the type (III), or which form the corresponding amount of this group (II), in which, the formula (I), PA0 X denotes --CO-- which is attached to a further R.sup.1 R.sup.2 C.dbd.CR.sup.3 group either directly or via the radical of a polyhydric alcohol or of an amine, PA0 R.sup.1 denotes hydrogen or a hydrocarbon radical having 1 to 10, preferably 1 to 4, carbon atoms, such as alkyl, phenyl, benzyl or naphthyl, PA0 R.sup.2 denotes hydrogen, a hydrocarbon radical having 1 to 10, preferably 1 to 4, carbon atoms, such as alkyl, phenyl, benzyl or naphthyl, an ester group containing the radical R.sup.4 of a monohydric alcohol having up to 12 carbon atoms, --CN, --NO.sub.2 or a CO--NHR.sup.1 or CO--R.sup.1 group, and PA0 R.sup.3 has the same meaning as R.sup.2 and is identical with or different from the latter, and in formula (II), --AH-- denotes one of the grouping --CH--, -…
