<p><P>PROBLEM TO BE SOLVED: To provide a white laminated polyester film having high surface strength and excellent in whiteness, the adhesion with various inks, water- resistance adhesion, antistatic properties and scratch resistance. <P>SOLUTION: The white laminated polyester film is constituted by providing a coating layer (C-layer) at least on the single surface of a substrate material comprising a white polyester film having a two or more-layered laminated structure. The substrate material is formed by laminating a polyester resin composition layer (A-layer), which comprises a polyester resin (II) and a master batch polyester resin (III) containing a white pigment, on at least the single surface of a layer (B-layer) mainly comprising a polyester resin (I) and the intrinsic viscosities of the polyester resins (I)-(III) satisfy a specific relational expression. The C-layer is provided just above the A-layer and contains a modified resin and a specific high-molecular antistatic agent. The breaking strength and the surface intrinsic resistance value of the C-layer are set to specific ranges. <P>COPYRIGHT: (C)2003,JPO</p> |
