    • A colorant composition for coloring keratin-containing fibers is disclosed having (a) at least one isatin derivative corresponding to the formula I: where R1 and R2 independently of one another represent a hydrogen atom, a halogen atom, a hydroxy group, a (C1-4)-alkyl, hydroxy-(C1-4)-alkyl, tertiary amino-(C1-4)-alkyl, (C1-4)-alkoxy group, an amino group optionally substituted by one or two (C1-4)-alkyl or hydroxy-(C1-4)-alkyl groups, a nitro, carboxy, or sulfo group, and Y is a hydroxy group, a (C1-4)-alkoxy group or an amino group which may be substituted by (C1-4)-alkyl, (C1-4)-alkoxy-(C1-4)-alkyl, carboxy-(C1-4)-alkyl, sulfo-(C1-4)-alkyl or hydroxy-(C1-4)-alkyl groups or which may be part of a heterocyclic 5-, 6- or 7-membered ring, or physiologically compatible salts thereof, and (b) at least one compound containing a primary or secondary amino group or hydroxy group selected from the group consisting of primary or secondary aliphatic or aromatic amines, nitrogen-containing heterocyclic compounds, amino acids, oligopeptides made up of 2 to 9 amino acids, aromatic hydroxy compounds, and CH-active compounds. The coloring composition does not require oxidizing agents and has very little, if any, sensitizing potential.
