| abstract | A dyestuff according to formula (I) or a salt thereof wherein the substituents have the definitions as defined in claim 1. The dyestuffs are useful for dyeing or printing nitrogen-containing or hydroxy-group-containing organic substrates and for the production of printing inks. A dyestuff according to formula (I) or a salt thereof, wherein the sulphonic acid group can be in 3- or 4- or 5- position of the phenyl ring, and RG, which is bonded in the 2- or 3- position of the naphthalene ring, signifies wherein X is chlorine or fluorine, Y is -NR4R5 and R4 and R5 are together with the nitrogen atom to which they are connected a heterocycle having 4 to 8 carbon atoms optionally containing another hetero-atom selected from O, N or S; or R4 is hydrogen or C1-4alkyl and R5 is C1-4alkyl which can be substituted by hydroxy, methyl or SO3H, or R5 is a group -A-SO2-B wherein A is a divalent group selected from C2-3alkylene or C5-8cycloalkylene and B is a group selected from -CH=CH2, -CH=CH-Z, -CH2CH2-Z or -CH(CH2Z)-CH2Z wherein Z is a group removable by alkali or X is Cl or F and Y signifies a radical of formula (Ia) wherein W is a C1-6 alkylene and all the substituents have the same definition as defined above with the proviso that W connects two identical radicals. |
