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