They are used in conventional carriers, e.g., in gel or emulsion form, preferably mixed before use or on the hair with an oxidizing agent to develop the color.Type: GrantFiled: November 19, 1992Date of Patent: April 13, 2004Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Guenther Konrad, Iduna Matzik, Edgar Lieske

Patent number: 6679923Abstract: The invention concerns a composition for dyeing keratin fibers, in particular human keratin fibers such as hair comprising at least one pyrazolin-4,5-dione of formula (I) and at least one aromatic primary amine. Said composition enables the dyeing of keratin fibers without an oxidizing agent in shades which are strong, varied, resistant and less selective than those of prior art. The invention also concerns dyeing methods and devices using said composition.Type: GrantFiled: July 11, 2002Date of Patent: January 20, 2004Assignee: L'Oreal S.A.Inventors: Laurent Vidal, Gérard Malle, Mireille Maubru
