Abstract: A light stabilizer composition containing a hindered amine compound obtained by the reaction between a 2,2,6,6-tetramethylpiperidinol and a carbonic ester and having improved handling properties. The composition contains (A) 100 parts by mass of silica having a water content of 2 to 7 wt % impregnated with (B) 10 to 300 parts by mass of a hindered amine compound represented by general formula (1). The composition preferably contains (C) 5 to 500 parts by mass of a benzotriazole light stabilizer represented by general formula (3). The symbols used in formulae (1) and (3) are as defined in the description.
