Abstract
PURPOSE: To obtain polyurethane with excellent weather resistance and heat resistance by compounding two kinds of specific compounds to polyurethane.
CONSTITUTION: To (A) polyurethane, 0.01W5wt%, pref., 0.05W2wt% of a compound shown by the formula I [wherein R1 is H, 1W10C straight-chain or branched alkyl, an aliphatic acid ester of COOR2 (wherein R2 is 1W18C straight- chain or branched alkyl); n is 2W3] and 0.01W5wt%, pref., 0.05W2wt% of a compound containing a skeletal structure shown by the formula II (wherein R2 is H, 1W4C alkyl) (e.g.: 4-benzoyloxy-2,2,6,6-tetramethylpiperidine) are compounded. Thereby, excellent stabilizing effect against resin degradation due to light, heat, water or oxygen is obtained.
