1. A 4-cycloalkyl- or 4-aryl-substituted aniline ether of the formula (VIII) in which R4 and R5 independently of one another are selected from the group consisting of —X, —CN, —SH, —SR″, —OR″, —(C═O)—R″, straight-chain, branched C1-12-alkyl, C2-12-alkenyl, C2-12-alkynyl groups, cyclic C3-8-alkyl, C4-8-alkenyl, C4-8-alkynyl groups or C5-18-aryl, C7-19-aralkyl and C7-19-alkaryl groups, where in the ring system of all of the cyclic groups mentioned above one or more carbon atoms may be replaced by heteroatoms selected from the group consisting of N, O, P and S and all of the groups mentioned above may be substituted by one or more groups selected from the group consisting of —R′, —X, —OR′, —SR′, —NR′2, —SiR′3, —COOR′, —CN and —CONR′2, where R′ represents hydrogen or a C1-12-alkyl group, which may be substituted by one or more heteroatoms selected from the group consisting of N, O, P and S, and R″ represents a C1-12-alkyl group, where in the ring system of all of the cyclic groups mentioned above one or more carbon atoms may be replaced by heteroatoms selected from the group consisting of N, O, P and S; R6 is selected from the group consisting of halogen atoms and C1-6-haloalkyl groups; R7 is selected from the group consisting of alicyclic C3-12-alkyl, C4-12-alkenyl, C4-12-alkynyl groups and C5-18-aryl, C7-19-aralkyl and C7-19-alkaryl groups, which may be substituted by one or more groups selected from the group consisting of —R′, —X, —OR′, —SO2—R′, —SR′, —NR′2, —SiR′3, —COOR′, —CN and —CONR′2, where R′ has the above meanings and where the C5-18-aryl, C7-19-aralkyl and C7-19-alkaryl groups may be substituted by one or more heteroatoms selected from the group consisting of N, O, P and S; wherein X is chlorine, bromine, fluorine, or iodine,and their salts.
