A stable, aqueous barrier coating composition includes: (a) prolamine; (b) cold water insoluble polymer; (c) water; (d) water-soluble co-solvent; and (e) stabilizer. The composition, when applied to a substrate, produces an article having a high surface energy and resistance to oil and grease penetration. A method of producing the article involves applying the composition to a substrate.

What is claimed is: 1. A stable, aqueous barrier composition consisting of (a) zein; (b) cold water insoluble polymer; (c) at least about 40 wt % to 79 wt % of polymer water; (d) the composition prepared with water-soluble co-solvent that functions as a co-solvent for the zein and a plasticizer in
What is claimed is: 1. A stable, aqueous barrier composition consisting of (a) zein; (b) cold water insoluble polymer; (c) at least about 40 wt % to 79 wt % of polymer water; (d) the composition prepared with water-soluble co-solvent that functions as a co-solvent for the zein and a plasticizer in a coating formed by the composition, the co-solvent included in an amount within a range of from 9 wt % to 43% wt % of the composition; and (e) stabilizer; and the composition containing substantially no acid; the composition adapted to form a barrier coating on a substrate having a high surface energy and resistance to oil and grease penetration as measured by a Kit number of at least 5. 2. The composition according to claim 1 wherein the stabilizer comprises a polymer, surfactant, or inorganic species. 3. The composition according to claim 1 wherein the stabilizer comprises a cellulose derivative. 4. The composition according to claim 3 wherein the stabilizer comprises carboxymethylcellulose. 5. The composition according to claim 1 wherein the cold water insoluble polymer comprises polysaccharide. 6. The composition according to claim 5 wherein the polysaccharide comprises starch. 7. The composition according to claim 6 wherein the stabilizer comprises carboxymethylcellulose. 8. The composition according to claim 6 wherein the starch comprises ethylated starch. 9. The composition according to claim 1 wherein the co-solvent consists essentially of a glycol. 10. The composition according to claim 9 wherein the co-solvent consists essentially of propylene glycol. 11. The composition according to claim 1 which contains about 50 wt % to 79 wt % water. 12. The composition according to claim 1 wherein the zein and the cold water insoluble polymer are added separately to the composition. 13. A method of producing an article comprising applying to a substrate a coating formed from a stable, aqueous barrier composition comprising: (a) prolamine; (b) cold water insoluble polymer; (c) from 40 wt % to 79 wt % water; (d) the composition prepared with water-soluble co-solvent that functions as a co-solvent for the prolamine and a plasticizer in a coating formed by the composition, the co-solvent included in an amount within a range of from 9 wt % to 43% wt % of the composition; and (e) stabilizer; and the composition containing substantially no acid; the coating being applied to the substrate to produce a barrier coating having a high surface energy, and the coating being applied to the substrate in a mariner sufficient to provide a barrier coating which is resistant to oil and grease penetration as measured by a Kit number of at least 5. 14. The method according to claim 13 wherein the prolamine in the composition comprises zein. 15. The method according to claim 13 wherein the article is selected from one or more of food packaging, textiles, nonwovens, foil, wood and paper products, furniture, masonry, leather, automobile finishes, plastics, cookware, and foams. 16. The method according to claim 13 wherein the composition does not require the use of an acid as a component in order to produce the stable aqueous barrier composition. 17. The method according to claim 13 wherein the co-solvent consists essentially of a glycol. 18. The method according to claim 17 wherein the co-solvent consists essentially of propylene glycol. 19. An article comprising a substrate and a coating on the substrate having been formed from a stable, aqueous barrier composition applied to the substrate, the composition consisting of: (a) zein; (b) cold water insoluble polymer; (c) water; (d) the composition prepared with water-soluble co-solvent that functions as a co-solvent for the prolamine and as a plasticizer in the coating formed by the composition; and (e) stabilizer; and the composition containing substantially no acid; the coating having been applied to the substrate to produce a barrier coating having a high surface energy, and the coating having been applied to the substrate in a manner sufficient to provide a barrier coating which is resistant to oil and grease penetration as measured by a Kit number of at least 5. 20. The article according to claim 19 wherein the article is selected from one or more of food packaging, textiles, non-wovens, foil, wood and paper products, furniture, masonry, leather, automobile finishes, plastics, cookware, and foams.
