Abstract
An easy-open end which is excellent from the standpoint of sanitation and environmental friendliness yet satisfying both the close adhesion and the scratch resistance despite of using a bisphenol A-free primer. The easy-open end has a polyester film applied, via a primer, onto the inner surface of the end of an aluminum base sheet forming a surface-treating layer that contains a zirconium compound and/or a titanium compound and an organic compound, wherein the primer contains a polyester resin that contains not less than 30% by weight of a carboxyl group-introduced polyester resin, and a phenol resin at a weight ratio of 50:50 to 85:15.
