The present invention relates to novel piperidine compounds of the formula (I) STR1 in which A is e.g. a group of the formula STR2 where R4 is e.g. hydrogen or methyl, X3 is e.g. --O-- or --NH-- and R5 ' is e.g. ethylene, propylene or decamethylene, R1 is e.g. methyl, methoxy, ethoxy or OH, R2 and R3 are e.g. methyl, m+n is e.g. a number from 1 to 40, n varies e.g. from zero to 50% of the sum m+n, X1 is e.g. as defined for R1 or is a group (CH3)3 SiO-- and X2 is e.g. hydrogen, methyl, ethyl, a group (CH3)3 Si-- or a group STR3 and, when m+n is a number from 3 to 10, X1 and X2 together also form a direct bond. The compounds of the formula (I) are effective in stabilising an organic material against thermal, oxidative and light-induced degradation.
