Independent claims are also included for the following: (1) a composition for oxidation dyeing of keratinic fibers, containing at least one compound (I); (2) a method for dyeing keratinic fibers, comprising applying at least one composition as in (1) to the fibers and developing the color with an oxidizing agent added to the composition just before use or applied separately (simultaneously or sequentially) in an oxidizing composition; (3) a kit comprising a compartment containing a composition as in (1) and a compartment containing an oxidizing composition. |
