Positively operating radiation-sensitive mixture containing a polyfunctional α-diazo-β-keto ester and radiation-sensitive recording material containing this mixture

A positively operating radiation-sensitive mixture comprising a binder which is insoluble in water but soluble or at least swellable in aqueous alkaline solution, and as a photoactive component a polyfunctional α-diazo-β-keto ester of the general formula I 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 STR2 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 --NR2 --, --C(O)--O--, --C(O)--NR2 --, --C(O)-- STR3 --NR2 --C(O)--NR3 --, --O--C(O)--NR2 --, --C(O)-- STR4 or --O--C(O)--O--, or CH groups can be replaced by STR5 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, is described. The radiation-sensitive mixture is particularly suitable for exposure using radiation of wavelength 190 to 300 nm.

Polyfunctional α-diazo-β-keto esters and their use in light-sensitive compositions

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.
