    • Disclosed is an easy adhesion film which attains sufficient adhesiveness in various processings without using any crosslinking agent such as a melamine resin to possibly pollute the environment and has a primer layer excellent in high-temperature hot water resistance. In the easy adhesion film, a coating film including a polyester resin and a crosslinking agent component in a content of 0.1% by mass or less, inclusive of 0% by mass, is formed on at least one side of a substrate film. The sum of the acid number and the hydroxyl number of the polyester resin is 50 to 200 mg KOH/g, wherein the acid number is 20 to 60 mg KOH/g and the hydroxyl number is 30 to 150 mg KOH/g. The amount of the oligomers contained in the polyester is 2.0% by mass or less. The thickness of the coating film is 0.001 to 0.5 μm.
