Abstract

Compounds of the formula (I) or salts thereof ##STR1## in which PA1 R.sup.1, R.sup.3 =H, (subst.) hydrocarbon radical (HC) or (subst.) heterocyclyl which, including substituents, have 1-30 carbon atoms, R.sup.2 =R.sup.0 --Q.sup.0 --, in which R.sup.0 =H, (subst.) HC or (subst.) heterocyclyl radical, in each case having 1-30 carbon atoms including substituents, and Q.sup.0 =a direct bond or --O--, --SO.sub.2-, --NH--, --N[(C.sub.1 -C.sub.6)alkyl]-, --CO--, --CO--NH-- or --O--CO--NH--; R.sup.4 =H, halogen, NO.sub.2, CN, (C.sub.1 -C.sub.4)alkyl, (C.sub.1 -C.sub.4)alkoxy, [(C.sub.1 -C.sub.4)alkyl]carbonyl or [(C.sub.1 -C.sub.4)alkoxy]carbonyl, where each of the last four radicals may be halogenated; R.sup.5 =H or (C.sub.1 -C.sub.4)alkyl; Q=O or NR*; R*=H. (C.sub.1 -C.sub.4)alkyl, (C.sub.3 -C.sub.4)alkenyl or (C.sub.3 -C.sub.4)alkynyl, where each of the last three radicals may be substituted by halogen, (C.sub.1 -C.sub.4)alkoxy and/or (C.sub.1 -C.sub.4)alkylthio, W=O or S; X,Y=H, halogen, (C.sub.1 -C.sub.4)alkyl, (C.sub.1 -C.sub.4)alkoxy, (C.sub.1 -C.sub.4)alkylthio, where each of the last three radicals may be substituted by halogen, (C.sub.1 -C.sub.4)alkoxy and/or (C.sub.1 -C.sub.4)al…
