Title:
ALUMINUM LID PROVIDED WITH COATING FILM COMPOSED OF AQUEOUS COATING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2010/013655
Kind Code:
A1
Abstract:
Disclosed is an aluminum lid which is obtained by shaping a coated aluminum base, which has a coating film composed of an aqueous coating material, so that the coating film forms the inner surface of the lid. The important characteristic of the aluminum lid is in that the coating film has a sea-island phase-separated structure wherein dispersion phases composed of a carboxyl group-containing acrylic resin are dispersed in a continuous phase composed of a base resin. Consequently, the aluminum lid is free from the problems of conventional aluminum lids using conventional aqueous coating materials, and thus has excellent corrosion resistance, openability and formability.
