    Abstract: PCT No. PCT/EP92/00281 Sec. 371 Date Jul. 16, 1993 Sec. 102(e) Date Jul. 16, 1993 PCT Filed Feb. 10, 1992 PCT Pub. No. WO92/14791 PCT Pub. Date Sep. 3, 1992.There are described benzophenoneazo dyes of the formula where the ring A can be benzofused and a benzofused ring A can be overbridged, m is 1 or 2, K is the radical of a coupling component, Y is hydrogen or arylazo, one of the two radicals X1 and X2 is hydrogen and the other is hydroxysulfonyl, R1, R2 and R3 are independently of the others hydrogen, halogen, C1-C12-alkyl, cyclohexyl, phenyl, 2-hydroxyethylsulfonyl or C1-C4-alkoxy or, when m is 1 and Y is hydrogen, one of these substituents can also be the radical of the formula where L1 is a chemical bond or a bridge member, and X1, X2, R4, K and the ring A are each as defined above, and R4 is hydrogen, halogen or C1-C4-alkoxy, with the proviso that there is at least one water-solubilizing group in the molecule, novel pyridone compounds, a process for preparing disulfonated pyridone compounds, and the use of the novel dyes for dyeing natural or synthetic substrates.
