Substituted 1,2-naphthoquinone-2-diazide-4-sulfonic acids are disclosed having the general formula A ##STR1## in which R is an alkyl, epoxyalklyl, alkylcarbonyl or alkylsulfonyl group, the carbon chains of which may be interrupted by oxygen atoms, or a substituted or unsubstituted aralkyl, arylcarbonyl or arylsulfonyl group and X is hydrogen, a metal or an ammonium group. A process for the preparation of the compounds is also disclosed. The compounds can be used as such, or preferably after condensation of their sulfonic acid chlorides with aromatic hydroxy compounds or amines to give the corresponding esters or amides, as light-sensitive compounds in radiation-sensitive mixtures or materials.
本文披露了一种具有一般式A的取代的1,2-萘醌-2-重氮-4-磺酸的化合物,其中R是烷基,环氧烷基,烷基羰基或烷基磺酰基,其碳链可由氧原子中断,或取代或未取代的芳基烷基,芳基羰基或芳基磺酰基,X是氢,金属或铵基。本文还披露了制备这些化合物的方法。这些化合物可以直接使用,或者更好地与芳香族羟基化合物或胺的磺酸氯化物缩合,得到相应的酯或酰胺,作为辐射敏感混合物或材料中的光敏化合物。
