Polyfunctional .alpha.-diazo-.beta.-keto esters of the general formula I are described ##STR1## in which R.sup.1 denotes an aliphatic, cycloaliphatic or araliphatic or aromatic radical having 4 to 20 carbon atoms, in which individual CH.sub.2 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 CH.sub.2 groups can be replaced by oxygen or sulfur atoms or by the groups ##STR2## in which R.sup.2 and R.sup.3 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 .gtoreq.2. The compounds mentioned are used as photoactive components in radiation-sensitive mixtures.
通用式I的多功能α-重氮-β-酮酯被描述为##STR1##其中R.sup.1表示具有4到20个碳原子的脂肪族、环脂族或芳基或芳香基团,其中单个CH.sub.2基团可以被氧原子或硫原子或N-或NH基团取代和/或含有酮基团,X表示具有2到22个碳原子的脂肪族、环脂族、碳环化合物、杂环化合物或芳基团,其中单个CH.sub.2基团可以被氧原子或硫原子或基团##STR2##所取代,在该基团中R.sup.2和R.sup.3独立地表示氢或脂肪族、碳环化合物或芳基,m表示2到10的整数,n表示0到2的整数,其中m-n是≥2。所述化合物被用作辐射敏感混合物中的光活性组分。
