A novel polyamine derivative, or polyol derivative, having a piperidylaminotriazine skeleton; salts of such compounds; a process for producing them; an organic material stabilizer comprising any of such compounds; a method of stabilizing an organic material; and a stabilized organic material. Compounds of the general formula: (1) (wherein X is N(R 4 ) or an oxygen atom; R 1 is an n-valent hydrocarbon group; R 2 is a hydrogen atom or an alkyl; R 3 is a hydrogen atom, an alkyl, an alkoxy or an acyl; R 4 is a hydrogen atom or an alkyl; and n is an integer of 3 to 16) are effective in the stabilization of an organic material against deterioration by light, heat, oxygen, ozone and electromagnetic waves, such as X-rays and γ-rays. |
