Abstract
Abstract Disclosed herein is a coating composition for coloring transparent containers such as glass bottles, the composition comprising a combination of a film-former such as an acrylic resin, a metal-free polymeric dye reactive with the resin, an adhesion promoter (and optionally an ultraviolet light absorber). Also disclosed are a method of coating containers with such a composition and the resulting product.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
50 words
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.
Claim 2
Dependent Claim
50 words
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.
Claim 3
Dependent Claim
38 words
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.
Claim 4
Dependent Claim
18 words
The water-based thermosetting coating composition of claim 1 wherein the colorant is a hydroxy-functional macromolecular chromophore-modified polymeric dye.
Claim 5
Dependent Claim
28 words
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.
Claim 6
Dependent Claim
20 words
The coating composition of claim 1 wherein the reactive dye absorbs light in the range of 360 to 760 nanometers.
Claim 7
Dependent Claim
59 words
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.
Claim 8
Dependent Claim
59 words
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.
Claim 9
Dependent Claim
20 words
An article of matter comprising a substrate to which has been applied the water-based thermosetting coating composition of claim 1.
Claim 10
Dependent Claim
23 words
The article of matter of claim 7 wherein the coating composition is applied at a film thickness of at least about 0.05 mils.
Claim 11
Dependent Claim
23 words
The article of matter of claim 7 wherein the coating composition is applied at a film thickness of no more than 0.3 mils.
Claim 12
Dependent Claim
14 words
An article of matter of claim 8 wherein the substrate is glass or plastic.
Claim 13
Dependent Claim
15 words
An article of matter of claim 9 which is in the form of a bottle.
