摘要:
The invention relates to a dyeing composition comprising a heterocyclic thiol/disulphide fluorescent colorant, 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 heterocyclic 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.
摘要:
L'invention concerne la coloration de matières kératiniques à l'aide de colorants hémicyanines styryles thiols et disulfures. L'invention a pour objet une composition de teinture comprenant un colorant thiol ou disulfure à chromophore hémicyanine styryle, un procédé de coloration avec effet éclaircissant de matières kératiniques, en particulier les fibres kératiniques, notamment humaines telles que les cheveux, mettant en oeuvre ladite composition. Elle a de même pour objet de nouveaux colorants à chromophore hémicyanine styryle thiol et leurs utilisations dans l'éclaircissement des matières kératiniques. Cette composition permet d'obtenir une coloration avec effet éclaircissant particulièrement tenace et visibles sur fibres kératiniques foncées.

Further, the present invention relates to novel styryl sulfide compounds, compositions thereof, especially comprising other dyes, and to processes for their preparation.
摘要:
L'invention a pour objet une composition comprenant i) au moins un colorant direct à fonction disulfure, un colorant direct à fonction thiol, ou un colorant direct à fonction thiol protégé et ii) au moins un polymère à fonction thiol, utilisée pour colorer les fibres kératiniques, notamment humaines telles que les cheveux. Elle a également pour objet le procédé de coloration des fibres kératiniques mettant en oeuvre ladite composition et l'utilisation de colorants directs à fonction disulfure associé au polymère à fonction thiol dans la coloration et l'éclaircissement des fibres kératiniques. Cette composition permet de nouveaux systèmes de coloration capillaire homogène, puissante, tenaces vis-à-vis des agents extérieurs et qui n'altèrent pas les propriétés cosmétiques des fibres kératiniques.
摘要:
The invention relates to a dyeing composition comprising a fluorescent disulphide dye, and to a method of dyeing plus lightening of keratin fibres, employing the said composition. It likewise relates to new fluorescent disulphide dyes and to their uses in the lightening of keratin materials.

摘要:
Fluorescent dyes useful for detecting a target material in biological assays an electron donating moiety which is linked by a conjugated π-electron bridge to an electron accepting moiety. The π-electron bridge includes at least one carbocyclic ring structure or heterocyclic ring structure. The electron accepting moiety is a carboxylic acid, a salt of a carboxylic acid, or has the formula (I) wherein X8 is selected from the group consisting of H, CH3, and (CH2)n6-Z2-, where Z2- is a monovalent anion; and n6 is an integer from 1 through 10; and Q3 is O or S.
