PROBLEM TO BE SOLVED: To provide a laminated polyester film which meets the adhesive properties with a water functional layer composed mainly of a water-soluble and hydrophilic resin such as a polyvinyl alcohol as represented by an printing ink receiving layer in ink jet printing and the resistance to heat and moisture. SOLUTION: This laminated polyester film is characterized in that a resin layer having a water droplet contact angle of 60 deg. or more and a surface free energy Lewis acid parameter of 0.1 mN/m or more is formed on at least one of the faces of a polyester film. |
