Abstract
Dyeable and dyed polymer-coatings on metal articles such as sliders, buttons, buckles, clasps, nuts, bolts, hooks, etc. include a substantial quantity of active proton acceptor groups relative to the number of polymer molecules in order to provide adequate dye pick-up.
Claims41
An article of manufacture comprising
- a metal member;
- a dyeable polymer coating on the member;
- said polymer coating including a quantity of active proton acceptor groups at least equal to 0.5 times the quantity of polymer molecules in the polymer coating to provide for dye pick-up in the polymer coating;
- said active proton acceptor groups being subject to irreversible transformation by heating above a predetermined temperature;
- said polymer coating being a coherent polymer film formed from a powdered polymer resin including said active proton acceptor groups and which is heated sufficiently to coalesce the powdered resin and form the coherent polymer film, but heated below the predetermined temperature to maintain a substantial quantity of active proton acceptor groups untransformed;
- and
- a dye in the polymer coating.

An article of manufacture comprising
- a metal member,
- a first layer of a synthetic polymer including a white pigment on said article,
- a second layer of a clear synthetic polymer on said first layer, said clear synthetic polymer layer being dyeable, and
- a dark dye in the second layer.
