The invention provides compositions which comprise, in an aqueous, alcoholic or aqueous-alcoholic vehicle, at least one compound of the general formula: STR1 in which R denotes a monohydroxyalkyl radical containing from 2 to 6 carbon atoms or a polyhydroxyalkyl radical containing from 3 to 6 carbon atoms. These dyeing compositions make it possible to obtain, on the hair, yellow shades with a very high chromaticity and possessing very good fastness to light and to washing.

Compounds having the general formula: STR1 in which R denotes hydrogen, a lower alkyl, lower hydroxyalkyl or lower polyhydroxyalkyl radical or alternatively an alkyl, hydroxyalkyl or polyhydroxyalkyl radical in which the alkyl chain is interrupted by one or more hetero-atoms such as oxygen are described. These compounds can be used in dyeing compositions for keratin fibres and wavesetting lotions. They make it possible to obtain very strong shades.
