Four light stabilizers have been synthesized and characterized, based on the substitution of an alicyclic amine group into the 4-position of 2-hydroxybenzophenone. The compounds prepared were bis-N,N'-alkylpiperazines, N-propoxymorpholinyl and 4-amino-2,2,6,6-tetramethylpiperidinyl derivatives. The
