摘要：
A resin composition comprising a resin, a hindered piperidinyloxy compound of the formula (I):
wherein R₁, R₂, R₃ and R₄ are independently a C₁-C₄ alkyl group and Z is a hydrogen atom or an organic group having at least one carbon atom, and a hypophosphite compound of the formula:
X a (H₂PO₂) b (II)
wherein X is a metal ion, an ammonium ion or a phosphonium ion, a and b are positive numbers provided that they satisfy the equation: a x c = b in which c is a valency of X, wherein the weight ratio of the hypophosphite compound (II) to the hindered piperidinyloxy compound (II) is at least 0.001, which has good heat stability and weather resistance.
