are attached may represent an alkylenedioxy group containing 1 to 4 carbon
atoms are present in a quantity of 0.1 to 20 millimoles per 100g of hair dye as
oxidation dye precursors and the carrier is a gel containing 1 to 20% by weight of
a soap or an oil-in-water emulsion containing 1 to 25% by weight of a fatty
component and 0.5 to 30% by weight of an emulsifier from the group of anionic,
nonionic, cationic, or ampholytic surfactants.

heterocyclic amino primary intermediate compounds.
6. Oxidation hair dyes as claimed in claim 5, wherein the indolines
correspond to formula I when the groups R1, R2, R3, R4, and R5 are hydrogen,
except that one of the groups R1, R2, and R3 may be a methyl group.
7. Oxidation hair dyes as claimed in claim 4, wherein the indolines

thereof are present in a quantity of 0.1 to 20 millimoles per 100g of hair dye as
oxidation dye precursors and the carrier is a gel containing 1 to 20% by weight of
a soap or an oil-in-water emulsion containing 1 to 25% by weight of a fatty
component and 0.5 to 30% by weight of an emulsifier from the group of anionic,
nonionic, cationic, or ampholytic surfactants.
10. A process as claimed in claim 3, wherein indolines of formula I or salts
thereof are present in a quantity of 0.1 to 20 millimoles per 100g of hair dye as
oxidation dye precursors and the carrier is a gel containing 1 to 20% by weight of
a soap or an oil-in-water emulsion containing 1 to 25% by weight of a fatty
component and 0.5 to 30% by weight of an emulsifier from the group of anionic,
nonionic, cationic, or ampholytic surfactants.
11. A process as claimed in claim 2, wherein indolines of formula I or salts
thereof are present in a quantity of 0.1 to 20 millimoles per 100g of hair dye as
oxidation dye precursors and the carrier is a gel containing 1 to 20% by weight of
a soap or an oil-in-water emulsion containing 1 to 25% by weight of a fatty
component and 0.5 to 30% by weight of an emulsifier from the group of anionic,
nonionic, cationic, or ampholytic surfactants.
