2-Cyanoacrylic esters (I) of alpha ,w-bis(4-hydroxy-2,2,6,6-tetramethylpiperid-1-yl)alkanes or (cyclo)aliphatic polyols of the given formula (I) are new. R<1>, R<2> = the radical of an iso- or heterocyclic ring system with at least one iso- or heteroaromatic ring and /- 1 of R<1> and R<2> is not H, n = 2-10, if n = 2, X = a gp. of formula (II), m = 2-8; if n = 3-10, X = the radical of an n-hydric 3-20C (cyclo)aliphatic polyol, opt. with 1 or 2 heteroatoms in the cycloaliphatic gp. and up to 8 non-adjacent O or S atoms or -NH- or 1-4C alkylimino gps. in the aliphatic chain. Also claimed are various materials stabilised against the action of light, O2 and heat with (I).
