Use of a 2,6-dinitro-aniline derivative as a dye in hair tinting products, whereby said derivative has the formula (I) in which R represents H, C1-C4 alkyl, C2-C4 monohydroxyalkyl or C3-C4 dihydroxyalkyl, and X represents one of the residues C1-C4 alkyl, C2-C4 monohydroxyalkyl, C1-C4 perfluoralkyl, C1-C4 alkoxy, C2-C4 monohydroxyalkoxy, C3-C4 dihydroxyalkoxy or halogen. A tinting agent for hair contains at least one compound having the formula (I) and new derivatives of 2,6 dinitro-aniline. The dyes of formula (I) have good physiological properties and offer all the tones of yellow required in tinting, ranging from a lemon yellow with a touch of blue to an orange red, passing through pure yellow. |
