POLYAMIDE RESIN COMPOSITION

PURPOSE: To obtain a polyamide resin composition having stable moldability even when a specified polyamide resin partly mixed with, for example, a recovered polymer or a thermally unstable compound is used as the polyamide resin. CONSTITUTION: This polyamide resin composition is obtained by mixing a polyamide resin composed mainly of nylon 6 with a mixture of a hindered phenol base antioxidant and a phosphorus antioxidant at a molar ratio of the former antioxidant to the latter of (1:5) to (5:1) in an amount of 0.01-5 pts.wt. based on 100 pts.wt. total composition, and it gives a molding of which the wavelength at which the primary regression line of a curve of transmittance ratios at 300-400nm crosses the primary regression line of a curve of transmittance ratios at 400-500nm exhibits at least 375nm when the ratio of the transmittance at each wavelength to that at 500nm is determined on the visible ultraviolet absorption spectrum.
