Composition useful for dyeing keratinic fibers, especially human hair, comprises a mixed dye comprising several different chromophores joined together by a linker

摘要

Dye composition comprises a mixed dye comprising several chromophores joined together by a linker. At least two of the chromophores are different and the chromophores are selected so that a composition containing 0.47 mmole/100 g of the mixed dye gives the following color parameters on a lock of 90% white hair: a* = 0 to +20, b* = 0 to +40; a* = -27 to 0, b* = 0 to +40; a* = 0 to +9, b* = -10 to 0; or a* = -14 to 0, b* = -21 to 0. Independent claims are also included for: (1) oxidation dyeing of keratinic fibers by applying a composition as above; (2) kit comprising a composition as above in one compartment and an oxidizing agent in another compartment; (3) dye as above.
