• m represents 0, 1, 2, 3 or 4,
• R6 represents hydrogen or alkyl,
• R7 and R8 independently of one another represent hydrogen or represent alkyl or alkenyl each optionally substituted one or more times by identical or different substituents selected from the group consisting of halogen, alkylcarbonyl, alkylcarbonyloxy, alkylamino, dialkylamino, alkoxy, alkylthio, alkoxyalkoxy, haloalkoxy, haloalkylthio and halogenalkoxyalkoxy;
• or represent cycloalkyl, cycloalkylalkyl, aryl, arylalkyl, saturated or unsaturated 5- to 10-membered heterocyclyl or heterocyclylalkyl each of which is optionally substituted one or more times by identical or different substitutents selected from the group consisting of halogen, alkyl, haloalkyl, alkoxy, haloalkoxy, alkylthio, haloalkylthio, alkylcarbonyl and alkoxycarbonyl,
• R6 and R7 further together represent alkylene optionally substituted one or more times by alkyl, or
• R7 and R8 further, together with the nitrogen atom to which they are attached, represent a saturated or unsaturated 5- to 10-membered heterocycle which may optionally contain a further heteroatom group from the series —O—, —S— and —NR9— and which may optionally be substituted one or more times by identical or different substituents selected from the group consisting of halogen, alkyl, alkoxy, alkylthio, haloalkyl, haloalkoxy and haloalkylthio, and
• R9 represents hydrogen, alkyl or alkenyl.
