(57) Abstract: [PROBLEMS] To provide a stabilizer and a composition comprising the same in order to improve the stability and processability of an organic material which is susceptible to thermal, oxidative and actinic disintegration. Organic materials and formulas susceptible to thermal, oxidative and actinic decays A composition comprising the compound represented by: and a conditionally novel compound described above. Preferred examples of the above compounds are: R = H, -O-C 1-12 alkyl such as; R 1 = H, alkyl of C 1-12; R 4, R 5 = H; n = 1; R 3 = H, -CO —C 1-4 alkyl, OR 3 is ortho to the alkenyl group of the formula; k = 0, 1; R 6 ═NO 2 , S-phenyl, SO 2 - phenyl. |
