Photochemically stabilized polyamide compositions |
摘要 |
A process for preparing photochemically stable dyed nylon compositions includes providing to a dyebath a shaped article of poly(epsilon-caprolactam) hydrolytically polymerized in the presence of water, a carboxylic acid chain regulator and a hindered piperidine derivative; and in the dyebath, dyeing the shaped article with one or more metalized or nonmetalized acid dyestuffs.
