Abstract

Unsaturated phenone derivatives of the general formula I ##STR1## where PA0 R.sup.1 is C.sub.1 -C.sub.4 -alkyl, cyclopropyl, cyclopentyl, cyclohexyl, indanonyl, tetralonyl, phenyl or phenyl in which some or all of the hydrogen atoms have been replaced by a C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy or C.sub.1 -C.sub.4 -thioalkyl group, or together with R.sup.2 or R.sup.6 forms an ethylene or propylene bridge, PA0 R.sup.2 to R.sup.6 are each hydrogen, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy or C.sub.1 -C.sub.4 -thioalkyl, and R.sup.3, R.sup.4 and R.sup.5 may each additionally be hydroxyl, R.sup.2 or R.sup.6 may additionally together with R.sup.1 form an ethylene or propylene bridge and one or more, but not more than three, of the radicals R.sup.2 to R.sup.6 are a group of the general formula II ##STR2## PA0 where PA0 K is C.sub.1 -C.sub.10 -alkylene which may contain 1 or 2 oxygen or sulfur atoms, PA0 Y is straight-chain or branched C.sub.1 -C.sub.10 -alkylene or is C.sub.1 -C.sub.10 -alkylene which is substituted by carboxyl, a carboxylate anion, an alkyl C.sub.1 -C.sub.4 -carboxylate group or hydroxyl, X is --NH-- or --(N-Alkyl)-- of 1 to 4 carbon atoms and PA0 Z …
