Ethylenically unsaturated compounds of the general formula I (see formula I) where R1 is alkyl of 1 to 4 carbon atoms, cyclopropyl, cyclo- pentyl, cyclohexyl, phenyl or phenyl in which some or all of the hydrogen atoms have been replaced by radicals R4, not more than two substituents R4 being identical, or R1 together with R2 or together with R6 forms a -CH2-CH2- or -CH2-CH2-CH2- bridge, R4 is alkyl of 1 to 24 carbon atoms, -OH, -O-R7, -S-R7, (see formulas II, III), -O-CH2-C.ident.N, -O-CH2-COOH, (see formulas IV, V, VI, VII, VIII) R2 or R6, independently of one another, both are hydro- gen, or one of the radicals R4, or, where R1 is aryl, R2 or R6 is a direct bond to R1 in the ortho-position with respect to the carbonyl group, and R3 and R5 are each hydrogen, one of the radicals R4 or a group of the general formula II (see formula IX) where R7 and R8 are each alkyl of 1 to 4 carbon atoms, R9 is cycloalkyl of 5 or 6 carbon atoms, R10 is hydrogen or alkyl of 1 to 4 carbon atoms and R11 is hydrogen or alkyl of 1 to 4 carbon atoms, with the proviso that either R3 or R5 is a group of the general formula II, are suitable for the preparation of polymers which, after exposure to actinic radiation, have increased internal strength.
