| abstract |
The invention relates to the dyeing of keratin materials using the dyes bearing an ascorbic acid-based unit of formula (I), particularly bearing 3,4-dihydroxyfuran-2(5H)-one and 2,3,4(5H)-furantrione units. The invention relates to a dye composition comprising a dye bearing an ascorbic acid-based group, and to a process for the dyeing, especially with a lightening effect, of keratin materials such as the hair, using the said composition. Similarly, the invention relates to novel dyes bearing an ascorbic acid-based group and to the uses thereof in the lightening of keratin materials. This composition affords colorations that are particularly fast and visible on dark keratin fibres, even in the absence of a chemical oxidizing agent. |
