Fibers, or articles prepared therefrom, of linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon are effectively dyed by contacting the fibers in aqueous dyebath under mild dyeing conditions in the substantial absence of a dye carrier. The dyed materials are useful in apparel fabrics.
