摘要： Isoindoline derivatives monosubstituted in the 1-position corresponding to the general formula ##STR1## in which the cyclic radical R is an aromatic ring, a substituted aromatic ring, a tetrahydrogenated aromatic ring, a nitrogen-containing heterocyclic ring, or a sulfur-containing heterocyclic ring, and R.sub.1 is a substituent represented by the general formula ##STR2## where Y is an atom of oxygen, nitrogen, sulfur, or carbon, Z is the atom or atoms necessary to form a 5-membered or 6-membered heterocyclic ring which may have a fused-on aromatic ring selected from phenyl and naphthyl groups, R.sub.2 is an alkyl, sulfoalkyl, or carboxyalkyl radical, and X.sup.- is the anion for the cationic quaternary nitrogen. The derivatives are dyes having hydrophilic properties. They are useful for dyeing and printing textile fibers and for photographic applications.

摘要： Many photographic materials must be handled under special lighting conditions in order to prevent exposure of the material. The use of large concentrations of bleachable light absorbing layers over the photosensitive emulsion tends to leave an undesirable residual stain. The inclusion of a specific class of low intensity reciprocity failure inducers to silver halide emulsions enables the emulsions and their photographic articles to be safely handled under white light conditions.
摘要翻译：许多照相材料必须在特殊照明条件下处理，以防止材料暴露。在感光乳剂上使用大量的可漂白的光吸收层会使留下不希望的残留污渍。将特定类别的低强度互易失效诱导剂包含在卤化银乳剂中使得乳液及其照相制品能够在白光条件下安全地处理。
