ABSTRACT OF THE DISCLOSURE In producing a dyeable coating on a metal article, such as a slider on a slide fastener, the article is coated with a powdered solid polymer resin containing active proton acceptor groups, such as amine groups. The powder coating is heated to convert the powder coating into a polymer film which is capable of being dyed by any of a wide variety of dyes to produce a desired color in the polymer film. During the heating, the temperature is maintained below the temperature at which substantially all the active proton acceptor groups would be transformed or rendered inactive.
