Water-soluble dyes of formula (I) in which R1 is hydrogen, hydroxyl, C1-4 alkyl, C1-4 alkoxy, halogen or SO3M, R2 is hydrogen, C1-4 alkyl or C3-6- cycloalkyl, B is the radical of a carbocyclic, heterocyclic or methylene- active non-cyclic coupling component having at least two optionally fused carbocyclic rings, and M is hydrogen or a non-chromophoric cation, the ring A has no further substituents or is substituted with from one to four of the following substituents: C1-4-alkyl, C1-4-alkoxy, halogen, -NO2, -COOM and - SO3M, and the group -N=N-B is bonded to position 3 or 4 of the ring A, with the proviso that the molecule contains at least two -SO3M groups, are suitable for dyeing or colouring non-fibrous substrates, in particular anodized aluminium or water-soluble plastic compositions.
L'invention concerne des colorants hydrosolubles de formule (I) dans laquelle R¿1? représente hydrogène, hydroxyle, alkyle C¿1-4?, alkoxy C¿1-4?, halogène ou SO¿3?M, R¿2? est hydrogène, alkyle C¿1-4? ou cycloalkyle C¿3-6?, B représente le radical d'un constituant de couplage carbocyclique, hétérocyclique ou à méthylène actif non cyclique ayant au moins deux noyaux carbocycliques éventuellement condensés, et M représente hydrogène ou un cation non chromophore. Le noyau A ne comporte pas de substituants additionnels, ou il substitué avec un à quatre des substituants suivants : alkyle C¿1-4?, alkoxy C¿1-4?, halogène, -NO¿2?, -COOM et SO¿3?M, et le groupe N=N-B est lié en position 3 ou 4 du noyau A, à condition que la molécule renferme au moins deux groupes SO¿3?M. Les colorants de la présente invention sont appropriés pour teindre ou colorer des substrats non fibreux, notamment de l'aluminium anodisé ou des compositions pastiques hydrosolubles.
