Abstract of the Disclosure Polyfunctional .alpha.-diazo-.beta.-keto esters of the general formula I are described (I) in which R1 denotes an aliphatic, cycloaliphatic or araliphatic or aromatic radical having 4 to 20 carbon atoms, in which individual CH2 groups can be replaced by oxygen or sulfur atoms or by N- or NH groups and/or contain keto groups, X denotes an aliphatic, cycloaliphatic, carbo-cyclic, heterocyclic or araliphatic radical having 2 to 22 carbon atoms, in which indivi-dual CH2 groups can be replaced by oxygen or sulfur atoms or by the groups -NR2-, -C(O)-O-, -C(O)-NR2-, -C(O)-N-, -NR2-C(O)-NR3-, -O-C(O)-NR2-, -O-C(O)-N- or -O-C(O)-O-, or CH groups can be replaced by -N-, in which R2 and R3 independently of one another represent hydrogen or an aliphatic, carbocyclic or araliphatic radical, m denotes an integer from 2 to 10 and n denotes an integer from 0 to 2, wherein m-n is ? 2. The compounds mentioned are used as photoactive com-ponents in radiation-sensitive mixtures. |
