Abstract

Methine dyes of the formula ##STR1## where K is a carbocyclic or heterocyclic radical, PA0 X is nitrogen or a radical of the formula C--Q.sup.1, and PA0 Q.sup.1, Q.sup.2 and Q.sup.3 are hydrogen, substituted or unsubstituted C.sub.1 -C.sub.6 -alkyl, C.sub.3 -C.sub.8 -cycloalkyl, substituted or unsubstituted phenyl, C.sub.1 -C.sub.6 -alkoxy, benzyloxy, substituted or unsubstituted phenoxy, C.sub.1 -C.sub.6 -alkylthio, halogen, cyano, formylamino or a radical of the formula R.sup.3, --CO--OR.sup.1, --CO--NHR.sup.1, --CO--NH--CO--R.sup.1, --CO--NH--CO--R.sup.3, --CO--NH--SO.sub.2 R.sup.3, --NH--CO--R.sup.1, --NH--CO--OR.sup.1, --NH--CO--NR.sup.1 R.sup.2, NH--CS--OR.sup.1, --NH--CS--NR.sup.1 R.sup.2, --NH--CO--R.sup.3, --NH--SO.sub.2 --R.sup.1, --NH--SO.sub.2 --R.sup.3 or --NH--SO.sub.2 --NR.sup.1 R.sup.2, wherein R.sup.1 and R.sup.2 are substituted or unsubstituted C.sub.1 -C.sub.13 -alkyl, C.sub.3 -C.sub.8 -cycloalkyl or substituted or unsubstituted phenyl, or else --NR.sup.1 R.sup.2 is amino, and R.sup.3 is a heterocyclic radical, or Q.sup.1 and Q.sup.2 are together with the carbon atoms to which they are attached a carbocyclic or heterocyclic ring, with the proviso that at least on…
