Benzotriazole compounds employed as development restrainer precursors are described having on one nitrogen atom an alkali-hydrolyzable, N,N-disubstituted carbamoyl group. The compounds may have the following formula: ##STR1## wherein: R.sup.1 and R.sup.2 each represent a substituted or unsubstituted alicyclic, aliphatic, aromatic or heterocyclic moiety, or may be taken together with the nitrogen to which they are attached to form a heterocyclic ring; and R.sup.3, R.sup.4, R.sup.5 and R.sup.6 each represent hydrogen, nitro, lower alkyl, halogen, carbamoyl, sulfamoyl, RCONH-- or RSO.sub.2 NH--, wherein R is lower alkyl or aryl.
描述了作为发展抑制剂前体的苯并三唑化合物,在一个氮原子上具有一个碱水解的N,N-二取代氨基甲酰基团。这些化合物可能具有以下结构式:##STR1## 其中:R.sup.1 和 R.sup.2 分别代表取代或未取代的脂环、脂肪、芳香或杂环基,或者可以与它们附着的氮一起形成杂环环;而 R.sup.3、R.sup.4、R.sup.5 和 R.sup.6 分别代表氢、硝基、低烷基、卤素、氨基甲酰基、磺酰基、RCONH-- 或 RSO.sub.2 NH--,其中 R 为低烷基或芳基。
