Azinoneutromethines of the formula (I) ##STR42## in which R.sup.1 represents C.sub.1 - to C.sub.22 -alkyl, C.sub.4 - to C.sub.10 -cycloalkyl, C.sub.7 - to C.sub.14 -aralkyl, C.sub.6 - to C.sub.10 -aryl, or a heterocyclic radical which is optionally bonded via C.sub.1 - to C.sub.2 -alkylene and contains 1 to 4 nitrogen, oxygen and/or sulphur atoms and 4 to 12 C atoms, it being possible for all these radicals optionally to be substituted,
- R.sup.2 and R.sup.3 independently of one another represent hydrogen, halogen, hydroxyl, cyano, C.sub.1 - to C.sub.8 -alkyl, C.sub.1 - to C.sub.8 -alkoxy, C.sub.4 - to C.sub.10 -cycloalkoxy, C.sub.7 - to C.sub.14 -aralkyloxy or C.sub.1 - to C.sub.20 -acylamino,
- R.sup.4 and R.sup.5 independently of one another represent cyano, C.sub.1 - to C.sub.8 -alkoxycarbonyl, C.sub.4 - to C.sub.7 -cycloalkoxycarbonyl, C.sub.6 - to C.sub.10 -aryloxycarbonyl, aminocarbonyl, mono-C.sub.1 - to C.sub.8 -alkylaminocarbonyl, di-C.sub.1 - to C.sub.8 -alkylaminocarbonyl, C.sub.6 - to C.sub.10 -arylaminocarbonyl, aminocarbonyl which is substituted by heterocyclic radicals which contain 5 to 7 atoms and contain N, S and/or O or phenyl which is substituted by cyano and/or nitro, or
- R.sup.4 and R.sup.5, together with the C atom in between, represent a ring which contains 5 or 6 atoms, optionally contains up to 2 nitrogen and/or oxygen atoms and is optionally substituted by cyano, halogen, C.sub.1 - to C.sub.4 -alkyl or C.sub.6 - to C.sub.10 -aryl, and
- A complements the ring in which it is located to form a
- 5- to 7-membered aromatic or quasiaromatic ring which is optionally benzo- or naphtho-fused, optionally contains a further nitrogen, oxygen or sulphur atom, and is optionally substituted by cyano, nitro, C.sub.1 - to C.sub.4 -alkyl, C.sub.7 - to C.sub.12 -aralkyl, C.sub.6 - to C.sub.10 -aryl, C.sub.1 - to C.sub.4 -alkoxy, a 5- to 6-membered ring which is optionally bonded via C.sub.1 - to C.sub.2 -alkylene and contains up to 2 N, S and/or O atoms, C.sub.1 - to C.sub.4 -alkylthio, C.sub.6 - to C.sub.10 -arylthio, amino, mono- or di-C.sub.1 - to C.sub.8 -alkylamino, C.sub.4 - to C.sub.8 -cycloalkyl-C.sub.1 - to C.sub.4 -alkylamino, C.sub.7 - to C.sub.12 -aryl-C.sub.1 - to C.sub.4 -alkylamino, mono- or di-C.sub.6 - to C.sub.10 -arylamino, pyrrolidino, piperidino, morpholino or C.sub.1 - to C.sub.6 -acylamino,
- represents CR.sup.B =CH, where R.sup.B =hydrogen or C.sub.1 - to C.sub.6 -alkyl, and
- x represents zero or 1.
