<P>PROBLEM TO BE SOLVED: To provide a printing polyester film that cannot be disabled to visually check hologram patterns, even if the metallic can receives retort processing, when a protective coating layer is formed at a metal plate for a can material or an outer surface side of a can barrel of a bottomed cylindrical can. <P>SOLUTION: The printing polyester film 1 is heated and bonded to the metal plate for a can material or outer surface side of a can barrel of a bottomed cylindrical can through the thermosetting resin system adhesive layer 5 and forms the protective coating layers 12 and 25. The hologram pattern layer 3 including unevenness in height difference of 0.1-2.0 μm is formed at one side surface of the polyester film 2 that becomes the base. At least a portion of the hologram pattern layer 3 contains the aluminum thin film pieces, a printing layer 4a comprising the resin composition comprising the epoxy butyral system resin and the polyisocyanate system resin, or the resin composition comprising the polyester polyurethane system resin polyisocyanate system resin, and a thermosetting resin system adhesive layer 5 is provided on the printing layer 4a. <P>COPYRIGHT: (C)2013,JPO&INPIT |
