Claim:
A composition for dyeing keratin materials comprising, in an appropriate medium: at least one cosmetic active ingredient, wherein the at least one cosmetic active ingredient is present in an amount ranging from 0.001% to 50% by weight and at least one 1,2-indandione derivative chosen from those of formulae (I) and (II): wherein: X, X1 and X2, which may be identical or different, are chosen from oxygen atoms, sulphur atoms, phosphorus atoms, and CR1R2 radicals; R1 and R2, which may be identical or different, are chosen from hydrogen atoms, halogen atoms, C3-C18 alkyl radicals, alkenyl radicals, carboxyl radicals, hydroxycarbonylalkyl radicals, hydrogenocarbonyl radicals, hydrogenocarbonylalkyl radicals, alkylcarboxyalkyloxy radicals, cyano radicals, thiocyano radicals, nitro radicals, nitroso radicals, hydroxyl radicals, hydroxyalkyl radicals, alkoxy radicals, alkenyloxy radicals, aryloxy radicals, amino radicals, alkylamino radicals, dialkylamino radicals, arylalkylamino radicals, diarylamino radicals, alkenylamino radicals, thio radicals, alkylthio radicals, arylthio radicals, alkenylthio radicals, aryl radicals, heteroaryl radicals, and quaternary ammonium radicals; A, A1 and A2, which may be identical or different, are chosen from fused and non-fused mono- and polyaromatic radicals comprising from 6 to 50 carbon atoms and which may comprise at least one heteroatom chosen from nitrogen, sulphur, oxygen and/or phosphorus; L is chosen from a single bond or aliphatic and aromatic divalent radicals, it being possible for the radical to comprise at least one heteroatom chosen from oxygen, sulphur, nitrogen and phosphorus and to be fused with A1 or A2, with the proviso that the at least one 1,2-indandione derivative chosen from those of formulae (I) and (II) is not chosen from 1,2-indandione
