Abstract:
1. A composition for dyeing keratin fibers, said composition comprising: (a) at least one keratin dyeing compound selected from aromatic systems which comprise at least one boronic acid or boronic ester moiety and which are capable of forming upon oxidation a nucleophile or an electrophile; (b) at least one additional keratin dyeing compound selected from the group consisting of auxiliary developers and auxiliary couplers; and (c) a cosmetically suitable medium wherein said aromatic systems which comprise at least one boronic acid or boronic ester moiety and which are capable of forming upon oxidation a nucleophile or an electrophile are selected from a compound according to one of the following formulas I to XV: wherein R1, R2, R3, R4, R7, R8, R9, R10, R11, R12, and R13 each are independently selected from the group consisting of: (a) C-linked monovalent substituents selected from the group consisting of: (b) S-linked monovalent substituents selected from the group consisting of SA (c) O-linked monovalent substituents selected from the group consisting of OA (d) N-linked monovalent substituents selected from the group consisting of NA (e) a halogen selected from the group consisting of F, Cl, Br, and I; (f) fluoroalkyl monovalent substituents selected from the group consisting of mono-, poly-, and per-fluoro alkyl systems comprising from about 1 to about 12 carbon atoms and from about 0 to about 4 heteroatoms; and (g) hydrogen; and
