ABSTRACT:
A dyed or undyed polyamide substrate, preferably film, fiber, or an article manufactured therefrom, with excellent breaking strength retention and ultimate elongation retention, is prepared by reacting a sufficient number of amine and/or amide-forming functional groups of a hindered amine with the end groups of the polyamide precursor(s) at a temperature sufficient for polymerization to occur, to thereby bind the hindered amine to the polyamide and inhibit migration, leaching, and volatilization of the hindered amine. The hindered amine is represented by the formula: ##STR1## in which R.sub.1 comprises the amine or amide-forming functional group;
