ABSTRACT:
A description is given of carrier-bound compounds of the formula I ##STR1## in which R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 independently of one another are hydrogen, halogen, nitro, cyano, CF.sub.3, C.sub.1 -C.sub.15 alkyl, C.sub.5 -C.sub.12 cycloalkyl, C.sub.2 -C.sub.15 alkenyl, C.sub.1 -C.sub.12 haloalkyl, C.sub.1 -C.sub.12 alkoxy, C.sub.1 -C.sub.12 alkylthio, C.sub.6 -C.sub.10 aryl, C.sub.6 -C.sub.10 aryloxy, C.sub.7 -C.sub.12 arylalkyl, --CO.sub.2 R.sub.6, --COR.sub.6 or ##STR2## in which at least one of the radicals R.sub.1 to R.sub.5 is hydrogen, halogen or C.sub.1 -C.sub.15 alkyl, and, in addition, the radicals R.sub.1 and R.sub.2, R.sub.2 and R.sub.3, R.sub.3 and R.sub.4 or R.sub.4 and R.sub.5 together with the carbon atoms to which they are attached form a benzo or cyclohexenyl ring,
