7-nitroindoline compounds are disclosed that comprise a triplet sensitising group such as substituted or unsubstituted benzophenone group and can be used to cage effector species. In particular, the inclusion of a triplet sensitising group linked to the 4 or 5 position of a 7-nitroindoline derivative provides compounds which can be photolysed to release the effector species with unexpectedly enhanced photolysis efficiency. The triplet sensitising group may be linked directly to the 7-nitroindoline or via a spacer group. In some examples, the triplet sensitising group and/or the spacer group can be selected to enhance other properties of the caged compound such as its solubility, spectroscopic properties or stability (e.g. stability of the linkage between the nitroindoline moiety and the triplet sensitiser). This can help to improve the performance of the caged compound, especially in aqueous environments containing dissolved oxygen.

The present invention relates to a composition for dyeing keratin fibres, comprising: at least one fatty substance, at least one surfactant; at least one oxidation base, at least one indoline coupler of formula (B7) or of formula (B8), and also salts thereof, optical and geometrical isomers and tautomers thereof, and hydrates thereof, formulae (B7) and (B8) being the following: at least one basifying agent; the fatty substance content representing in total at least 25% by weight relative to the total weight of the composition; at least one oxidation base being chosen from heterocyclic oxidation bases when the coupler is of formula (B7). The present invention also relates to a process using this composition in the presence of at least one chemical oxidizing agent, and to multi-compartment devices suitable for the implementation of the invention.

significantly enhanced extent of photochemical cleavage in aqueous solution over their non-sensitised analogues and release the carboxylate derived from their 1-acyl group. The present work investigates length and functional group effects in the linker between the benzophenone sensitiser and the nitroindoline and concurrently establishes a more efficient synthetic route to an effective conjugate than
