ABSTRACT:
The invention provides a synthetic resin composition having better weather resistance than ever, and an automotive interior/exterior material using the same.The synthetic resin composition contains a hindered amine compound (A) having a partial structure represented by the following general formula (1):in an amount of 0.01 to 20 parts by mass with respect to 100 parts by mass of the synthetic resin; and a benzoate compound (B) represented by the following general formula (2):in an amount of 0.01 to 20 parts by mass with respect to the same, at a component mass ratio of (A)/(B) between 1/1 and 1/5.In the synthetic resin composition according to the present invention, the component mass ratio of the hindered amine compound (A) to the benzoate compound (B), namely {(A)/(B)}, is preferably between 1/2 and 1/4.
