Abstract:
1. A process for tinting a transparent, tintable, abrasion-resistant coating that is coated on at least one surface of a substrate, comprising: applying a polyurethane dispersion based primer to at least one surface of a polycarbonate or polyamide substrate; contacting the primer applied to the substrate with a coating composition that forms a transparent, tintable, abrasion-resistant coating upon curing, the coating composition comprising: curing the coating composition to form a transparent, tintable, abrasion-resistant cured coating; and tinting the cured coating by immersing the coated surface of the substrate in a dye bath for the cured coating to absorb or transmit an amount of dye sufficient to allow up to about 50 percent light transmittance through the coated substrate.
