Abstract: Pyridine compounds of the general formula where one radical X is phenyl and the other radical X is phenyl which is substituted by halogen, cyano, C1-C5-alkyl, C1-C5-alkoxy or C1-C5-alkoxycarbonyl, or both radicals X are 4-fluorophenyl, and X1 is a radical of the formula where R1 and R2 independently of one another are each straight-chain or branched alkyl, cyanoalkyl, haloalkyl, aryl or aralkyl having a total of 7 to 14 carbon atoms, or is a 5-membered or 6-membered saturated heterocyclic radical and R3 is straight-chain or branched C1-C4-alkyl, are described. The compounds (I) are dye precursors for pressure-sensitive recording systems.
