ABSTRACT DESCRIPTION The invention relates to new compounds corresponding to the general formula: (I) in which X denotes a halogen atom, R and R 'denote independently of each other a hydrogen atom or a alkyl, polyhydroxyalkyl, hydroxyalkoxyalkyl radical, alkoxyalkyl or aminoalkyl optionally substituted on the nitrogen atom, provided that at least one of the groups R and R 'represents a polyhydroxyalkyl, alkoxyalkyl radical or hydroxyalkoxyalkyl. The compounds according to the invention are especially useful as yellow dyes in coloring direct or in oxidation coloring to bring reflections complementary to the basic coloring. These new com layered give the hair stable colors when washed, to light and weather and stand out particularly particularly by their good resistance to washing. |
