The present invention provides a light stabilizer composition having improved handling properties of a hindered amine compound obtained by reacting 2,2,6,6-tetramethylpiperidiol with a carbonic ester, and more specifically, (A) a light stabilizer composition having a water content of 2 And 10 to 300 parts by weight of the hindered amine compound (B) represented by the general formula (1), based on 100 parts by weight of the silica to 7 wt% of the silica. It is also preferable to blend 5 to 500 parts by weight of the benzoate light stabilizer (C) represented by the general formula (3). Details of the general formulas (1) and (3) are as described in the present specification. |
