摘要：
An indoline derivative of the formula (I) ##STR1## in which R.sup.1 denotes H or C.sub.1 -C.sub.8 -alkyl;R.sup.2 and R.sup.3 are identical or different and denote C.sub.1 -C.sub.8 -alkyl;R.sup.4 -R.sup.9 are identical or different and denote H, C.sub.1 -C.sub.8 -alkyl, C.sub.5 -C.sub.6 -cycloalkyl or phenyl-C.sub.1 -C.sub.4 -alkyl, or R.sup.5 and R.sup.6 connected together to form a further C.sub.5 -C.sub.6 ring, andR.sup.10 denotes H or one or more radicals selected from the group consisting of C.sub.1 -C.sub.8 -alkyl, C.sub.1 -C.sub.8 alkoxy, C.sub.5 -C.sub.6 -cycloalkyl, phenyl-C.sub.1 -C.sub.4 -alkyl and carb-C.sub.1 -C.sub.8 -alkoxy radicals, or halogen atoms. Such indoline derivative is useful as a UV absorber.
