Claims
- 1. A water-based, thermosetting, transparent colorant coating composition comprising: (i) a film-former including a resin and an internal or external crosslinking agent; (ii) a metal-free polymeric dye which is reactive with the film-former; and (iii) an adhesion promoter in an effective combination to form a transparent thermoset coating for coloring containers.
- 2. The water-based thermosetting coating composition of claim 1 wherein the film-former is selected from the group consisting of an acrylic polymer, a polyester, a polyether, an epoxy polymer, a polyurethane, an aminoplast, a phenoplast or a mixture thereof.
- 3. The water-based thermosetting coating composition of claim 1 wherein the colorant is a hydroxy-functional macromolecular chromophore-modified polymeric dye.
- 4. A water-based thermosetting coating composition of claim 1 wherein the colorant is present in an amount of about 0.2 to 50 percent by weight based on resin solids.
- 5. The coating composition of claim 1 wherein the reactive dye absorbs light in the range of 360 to 760 nanometers.
- 6. A process for coloring a light-transmitting container comprising coating the container with a thermosetting, water-based coating composition comprising a film-former including a resin and an internal or external crosslinking agent, a metal-free polymeric dye which is reactive with the film-former, and an adhesion promoter in an effective combination to form a coating which partially absorbs transmission of visible light.
- 7. An article of matter comprising a substrate to which has been applied the water-based thermosetting coating composition of claim 1.
- 8. The article of matter of claim 7 wherein the coating composition is applied at a film thickness of at least about 0.05 mils.
- 9. The article of matter of claim 7 wherein the coating composition is applied at a film thickness of no more than 0.3 mils.
- 10. An article of matter of claim 8 wherein the substrate is glass or plastic.
- 11. An article of matter of claim 9 which is in the form of a bottle.
