Abstract:
1. A composition for dyeing a keratin material comprising: a medium appropriate for dyeing a keratin material and at least one 1,3-indandione derivative comprised in said medium in an amount sufficient for dyeing a keratin material and chosen from compounds of formulae (I), (II) and (III) wherein X, X A A L is a single bond or an aliphatic or aromatic divalent radical, which may comprise at least one heteroatom chosen from oxygen, sulphur, nitrogen and phosphorus and may be fused with at least one of A n is an integer chosen from 0, 1, 2, 3, and 4, R is chosen from halogen atoms, alkyl radicals, alkenyl radicals, a carboxyl radical, alkoxycarbonyl radicals, hydroxycarbonylalkyl radicals, a hydrogenocarbonyl radical, hydrogenocarbonylalkyl radicals, alkylcarboxylalkyloxy radicals, a cyano radical, a thiocyano radical, a nitro radical, a nitroso radical, a sulphonato radical, alkylsulphonamido radicals, a hydroxyl radical, hydroxyalkyl radicals, alkoxy radicals, alkenyloxy radicals, aryloxy radicals, an amino radical, alkylamino radicals, dialkylamino radicals, arylalkylamino radicals, diarylamino radicals, alkenylamino radicals, a thio radical, alkylthio radicals, arylthio radicals, alkenylthio radicals, a silyl radical, C wherein B and D, which may be identical or different, are each chosen from carbon and nitrogen atoms and W is a ring of at least 5 members or an aromatic or heteroaromatic, fused or non-fused polycycle, wherein the heteroatom may be chosen from nitrogen, oxygen, sulphur and phosphorus, with the following provisos when X is a radical CR 1 R 2 , n is equal to 0 and R 1 is OH, then R 2 is not an amino, alkylamino, dialkylamino, arylalkylamino, diarylamino or alkenylamino radical.
