Abstract (en)
[origin: WO2008151858A2] The invention relates to dyes containing at least one dye precursor for a natural-looking dye selected from the group of indol or indolin derivatives, at least one organic compound carrying at least one thiol group in the molecule, and at least one alkalising agent, said dyes being free of additional oxidants and enzymes catalysing the chromogenic constituents. The dyes according to the invention provide more intense colouring on substrates containing keratin.
