Unsaturated phenone derivatives and their use as contact adhesives

Abstract

Abstract Unsaturated phenone derivatives of the general formula I <IMAGE> I where R1 is C1-C4-alkyl, cyclopropyl, cyclopentyl, cyclohexyl, indanonyl, tetralonyl, phenyl or phenyl in which some or all of the hydrogen atoms have been replaced by a C1-C4-alkyl, C1-C4-alkoxy or C1-C4-thioalkyl group, or together with R2 or R6 forms an ethylene or propylene bridge, R2 to R6 are each hydrogen, C1-C4-alkyl, C1-C4-alkoxy or C1-C4-thioalkyl, and R3, R4 and R5 may each additionally be hydroxyl, R2 or R6 may additionally together with R1 form an ethylene or propylene bridge and one or more, but not more than three, of the radicals R2 to R6 are a group of the general formula II <IMAGE> II or III <IMAGE> III where K is C1-C10-alkylene which may contain 1 or 2 oxygen or sulfur atoms, Y is straight-chain or branched C1-C10-alkylene or is C1-C10-alkylene which is substituted by carboxyl, a carboxylate anion, an alkyl C1-C4-carboxylate group or hydroxyl, X is -NH- or -(N-Alkyl)- of 1 to 4 carbon atoms and Z is hydrogen or C1-C4-alkyl.
