Abstract:
1. A method of coating a paper substrate, the method comprising the steps of: forming a composition by contacting starch and a synthetic polymer during a starch cooking process in a fluid, the fluid being at temperature and conditions such that the starch remains insolubly suspended in the fluid, cooking the composition under temperature and conditions sufficient to gelatinize the starch and to open up the starch to water penetration and to form a complex with the synthetic polymer but the temperature and pressure being insufficient to form covalent bonds between the starch and the synthetic polymer, and applying the composition to a paper substrate, wherein the composition excludes pigment and the synthetic polymer is not a starch, and wherein the composition is applied to a paper substrate by one device selected from the list consisting of: a size press device, print roll coater device, air-knife coater device, metering bar coater device, blade coater device, under vacuum coater device, cast coating device, and any combination thereof.
