    Abstract: Triazolopyridines of the formula where R1 is C1-C20-alkyl which may be substituted, phenyl which may be substituted, or hydroxyl, R2 is hydrogen, formyl, nitroso, cyano or substituted methyl, R3 is hydrogen, cyano, carbamoyl, carboxyl or C1-C4-alkoxycarbonyl and R4 is hydroxyl, halogen, amino which may be substituted or the radical of a compound with an acidic CH, are prepared as described. The compounds are useful as intermediates in the preparation of dyes.

    Abstract: Azo dyes of formula (I) are new: (where R1 = (a) opt. substd. 1-20C alkyl opt. interrupted by one or more O atoms, or (b) opt. substd. phenyl; R2 = CN, CONH2, COOH or 2-5C alkoxycarbonyl; R3 = OH, NY1Y2 or the residue of a CH-acidic cpd.; Y1 and Y2 = H or 1-4C alkyl, or NY1Y2 is a 5- or 6-membered satd. heterocyclic gp.; D = the residue of an aniline-series diazo component). (I) are prepd. by diazotising DNH2 and coupling with a 5-methyl-(1,2,4) trizolo(1,5-a) pyridine deriv. of formula (II): Cpds. (II) are described in DE3926770. USE - (I) are esp. useful for dyeing cellulose ester or polyester fibres, but may also be used to dye polyamides or polyester/cellulose blends.
