Abstract Translated from German Triazolopyridinfarbstoffe der Formel in der R¹ gegebenenfalls substituiertes C₁-C₂₀-Alkyl, gegebenenfalls substi­tuiertes Phenyl oder Hydroxy, R² einen carbocyclischen oder heterocyclischen Rest, R³ Cyano, Carbamoyl, Carboxyl oder C₁-C₄-Alkoxycarbonyl, R⁴ Sauerstoff oder einen Rest der Formel wobei L¹ für C₁-C₈-Alkyl, das gegebenenfalls durch 1 oder 2 Sauerstoffatome unterbrochen ist, steht, und X CH oder Stickstoff bedeuten, sowie ein Verfahren zum thermischen Transfer von Methinfarbstoffen. Triazolopyridine dyes of the formula in the R¹ optionally substituted C₁-C₂₀ alkyl, optionally substituted phenyl or hydroxy, R² is a carbocyclic or heterocyclic radical, R³ cyano, carbamoyl, carboxyl or C₁-C₄ alkoxycarbonyl, R⁴ oxygen or a radical of the formula where L¹ is C₁-C₈ alkyl, which is optionally interrupted by 1 or 2 oxygen atoms, and X is CH or nitrogen, and a process for the thermal transfer of methine dyes.
