A food or beverage can post repair coating composition comprising an acrylic latex material.
First claim
Opening claim text (preview).
The invention claimed is: 1. A food or beverage can comprising a varnish layer, a score line, and a repair coating applied to at least a portion of the score line, wherein the repair coating comprises an acrylic latex material. 2. A method of repairing a score line on a food or beverage can, the method comprising applying to the score line repair coating composition, the repair coating composition comprising an acrylic latex material. 3. A can according to claim 1 , wherein the acrylic latex material comprises an aqueous emulsion of one or more acrylic polymers. 4. A can according to claim 1 , wherein the acrylic latex material comprises an aqueous dispersion of an acrylic material in a core/shell arrangement. 5. A can according to claim 4 , wherein the core is formed from a core mixture and the shell is formed from a shell mixture, and wherein the ratio of the core mixture (monomers and initiator) to shell mixture (monomers and initiator) is 20:80 to 90:10 by weight. 6. A can according to claim 4 , wherein the acrylic latex material comprises an aqueous dispersion of an acrylic material with reactive functional groups and stabilized with an emulsifier or surfactant material. 7. A can according to claim 1 , wherein the coating composition is substantially free of bisphenol A and derivatives or residues thereof. 8. A method according to claim 2 , wherein the coating composition is substantially free of bisphenol A and derivatives or residues thereof. 9. The food or beverage can of claim 1 , wherein the acrylic latex material cures upon drying and/or heating. 10. The method of claim 2 , wherein the acrylic latex material cures upon drying and/or heating.
