ABSTRACT:
A polyamide resin composition, with a sufficiently high weather resistance even when the polyamide resin contains a pigment containing a metal component such as titanium oxide, or a residual catalyst containing a metal component, is provided by a polyamide resin composition comprising from 0.05 to 2 parts by weight of an N—O—R type low-molecular-weight hindered amine light-resistant stabilizer and a high-molecular-weight hindered amine light-resistant stabilizer per 100 parts by weight as a total of the composition.
