  • Patent number: 8119802
    Abstract: This invention relates to process for preparing fluorinated dyes selected from the group consisting of compounds of the general formulae (I) and (III) and mixtures thereof by reacting the corresponding compounds which do not have R12 or R30 as substituents with compounds of the general formula R12A or R30A where A is selected from the group consisting of I and Br, the compounds obtained from said process and the use of these fluorinated dyes in electrophoretic displays.

  • Publication number: 20120031422
    Abstract: The invention relates to a dyeing composition containing a thiol/disulphide fluorescent colorant comprising a heterocycle, and to a method for colouring keratin materials, especially keratin fibres, particularly human keratin fibres such as hair, with a lightening effect, using said composition. The invention also relates to novel thiol/disulphide fluorescent colorants and the uses thereof for lightening keratin materials. Said composition produces a lightening effect which is especially tenacious and visible on dark keratin fibres.

  • Patent number: 8075638
    Abstract: The invention relates to the dyeing of keratin materials using dichromophore dyes with a carbonyl or heterocyclic linker. The invention relates to a dye composition comprising a dye with a carbonyl or heterocyclic linker, and to a dyeing process with a lightening effect on keratin materials, in particular keratin fibers, especially human keratin fibers such as the hair, using said composition, optionally in the presence of a cosmetically acceptable acid or base. It similarly relates to novel dyes and to the uses thereof in lightening keratin materials. This composition makes it possible to obtain a coloring with a lightening effect which is particularly resistant and visible on dark keratin fibers.
