Sulfilimine compounds of formula I ##STR1## wherein X is the integrating residue of a photographically active compound H.sub.2 N--A--X and A is a linking member between X and N consisting of a benzene ring having at least two electron-attracting groups are suitable compounds for photographic recording materials. The compounds can be split reductively to release the photographically active compound. Where the photographically active compound is a dye or dye precursor the sulfilimine compounds are suitable dye releasers for color diffusion transfer processes.
公式I中的Sulfilimine化合物 ##STR1## 其中X是具有照相活性化合物H.sub.2 N--A--X的整合残基,A是连接X和N之间的连接成员,由至少具有两个电子吸引基团的苯环组成,适用于照相记录材料的化合物。这些化合物可以通过还原分裂释放出照相活性化合物。如果照相活性化合物是染料或染料前体,则这些Sulfilimine化合物适用于彩色扩散转移过程的染料释放剂。
