<p><P>PROBLEM TO BE SOLVED: To provide a polyester film for covering a drawn/ironed can which is applicable to a metal plate, particularly, a so-called two-piece can and is excellent in formability and adhesion, to provide a polyester-film-coated metal plate for the drawn/ironed can excellent in formability, and further to provide the drawn/ironed can covered with the polyester film excellent in dent-proof characteristic and appearance. <P>SOLUTION: The polyester film is a laminated polyester film comprising two layers of a polyester layer A and a polyester layer B, and the polyester layer B contains 1 to 8 mol%, based on the total acid components of the polyester raw material, of aliphatic dicarboxylic acids having 10 or more carbon atoms. When the laminated polyester film is stuck on the metal plate so that the layer B contacts the metal plate, the surface of the layer A has a coefficient of dynamic friction of not more than 0.30 of measured under 50°C environment using a steel ball as a slider. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
