Patent number: 4783497Abstract: Coating compositions suitable for use as coatings or inks for metallic foils, such as aluminum foil, as well as for use on other materials, such as papers and plastics resin films, are disclosed. These compositions comprise a water dispersable polyester resin, an alkylated amino resin and water. They may optionally include a pigment and other optional modifying ingredients. These compositions, being water-based, provide improved environmental compatibility and may be dried under relatively low temperatures without objectional ammonia residue odor.Type: GrantFiled: December 16, 1985Date of Patent: November 8, 1988Assignee: Reynolds Metals CompanyInventor: Gerald L. Thompson
