The invention relates to novel thienone compounds useful in dyeing fibers, of the formula: ##STR1## where R.sup.1 is cyano, C.sub.1 -C.sub.4 -alkoxycarbonyl, carbamoyl or C.sub.1 -C.sub.4 -monoalkylcarbamoyl or -dialkylcarbamoyl, R.sup.2 is hydrogen, C.sub.1 -C.sub.8 -alkyl, substituted or unsubstituted phenyl, furyl, thienyl or halogen, X is nitrogen or CR.sup.4 where R.sup.4 is hydrogen, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxycarbonyl, cyano or substituted or unsubstituted phenyl, and R.sup.3 is an aniline, thiazole, indole, styrol or isoindole radical, with the proviso that if R.sup.1 is cyano, X is CH and R.sup.3 is 4-dimethylaminophenyl or styryl, then R.sup.2 is not methyl or phenyl and that if R.sup.1 is cyano, X is CH and R.sup.3 is phenyl or 4-methoxyphenyl, then R.sup.2 is not phenyl.
A thienone compound of the formula ##STR119## where R.sup.1 is cyano, C.sub.1 -C.sub.4 -alkoxycarbonyl, carbamoyl or C.sub.1 -C.sub.4 -monoalkylcarbamoyl or -dialkylcarbamoyl,
A method of dyeing fibers comprising applying a thienone compound of the formula ##STR124## where R.sup.1 is cyano, C.sub.1 -C.sub.4 -alkoxycarbonyl, carbamoyl or C.sub.1 -C.sub.4 -monoalkylcarbamoyl or -dialkylcarbamoyl,
