ABSTRACT:
A hair coloring composition, and a method for using the composition, are described, in which as coupler substance, in addition to customary couplers if desired, a compound of the formula ##STR1## is employed. The novel couplers are more physiologically suitable for use in hair colorings than the prior art couplers, and allow for the preparation of compositions which lead to highly stable colorings over a broad range of shades and tones.
