Abstract
The invention relates to the dyeing of keratin materials using naphthylimide thiol/disulphide thiol fluorescent dyes, and to a dyeing process which has a lightening effect on keratin materials, in particular keratin fibres, especially human keratin fibres such as the hair, using said composition. It similarly relates to novel thiol/disulphide fluorescent dyes and to uses thereof in lightening keratin materials.This composition makes it possible to obtain a particularly resistant and visible lightening effect on dark keratin fibres.
