, (2008/06/13)
Polyfunctional α-diazo-β-keto esters of the general formula I are described STR1 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, carbocyclic, heterocyclic or araliphatic radical having 2 to 22 carbon atoms, in which individual CH2 groups can be replaced by oxygen or sulfur atoms or by the groups STR2 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 components in radiation-sensitive mixtures.
