<p><P>PROBLEM TO BE SOLVED: To provide a laminated polyester film excellent in wet-heat adhesiveness relative to a printing layer, and moreover, excellent in transparency and antistatic properties. <P>SOLUTION: The laminated polyester film includes a layer X having a polyester resin (A), acrylic resin (B) and polystyrene sulfonate (C) at least on one surface of the polyester film. The polyester resin (A) is a polyester resin obtained by copolymerizing a dicarboxylic acid component having a sulfonate group. Moreover, the sum total ((a)+(b)) of the content (a) of the polyester resin (A) relative to the total weight of the layer X and the content (b) of the acrylic resin (B) relative to the total weight of the layer X is 60-90 wt.% relative to the total weight of the layer X, and the content of the polystyrene sulfonate (C) is 10-40 wt.% relative to the total weight of the layer X. Moreover, (a)/(b) is 0.11 or more, and less than 0.68, and a haze is 5% or less. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
