##STR00001## Described are amino substituted hydroxyphenyl benzophenone derivatives of formula (I), wherein R.sub.1, and R.sub.2 independently from each other are; C.sub.1-C.sub.20alkyl; C.sub.2-C.sub.20-alkenyl; C.sub.3-C.sub.10cycloalkyl; C.sub.3-C.sub.10cycloalkenyl; or R.sub.1, and R.sub.2 together with the linking nitrogen atom form a 5- or 6-membered heterocyclic ring; n.sub.1 is a number from 1 to 4; when n.sub.1=1, R.sub.3 is a saturated or unsaturated heterocyclic radical; hydroxy-C.sub.1-C.sub.5alkyl; cyclohexyl optionally substituted with one or more C.sub.1-C.sub.5alkyl; phenyl optionally substituted with a heterocyclic radical, aminocarbonyl or C.sub.1-C.sub.5alkylcarboxy; when n.sub.1 is 2, R.sub.3 is an alkylene-, cycloalkylene- or alkenylene radical which is optionally substituted by a carbonyl- or carboxy group; o R.sub.3 together with A forms a bivalent radical of the formula (Ia), wherein n.sub.2 is a number from 1 to 3; when n.sub.1 is 3, R.sub.3 is an alkanetriyl radical; when n.sub.1 is 4, R.sub.3 is an alkanetetrayl radical; A is --O--; or --N(R.sub.5)--; and R.sub.5 is hydrogen; C.sub.1-C.sub.5alkyl; or hydroxy-C.sub.1-C.sub.5alkyl. The compounds are useful as UV filters in sunscreen applications.
