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