PROBLEM TO BE SOLVED: To provide a laminated polyester film having high transparency, blocking resistance, and excellent adhesion to a hard coat layer and UV ink. SOLUTION: A laminated polyester film having a coating layer on at least one surface of a polyester film base material, and a composition containing a urethane resin in which the coating layer has a polycarbonate structure, a cross-linking agent, and a polyester resin is cured. Therefore, the maximum value of the distribution curve of nitrogen elements based on the element distribution measurement in the depth direction of the coating layer exists near the surface of the coating layer on the opposite side of the polyester film base material, and the polyester film base material. A laminated polyester film in which an appropriate amount of polycarbonate structure is present on the surface of the coating layer on the opposite side. [Selection diagram] Fig. 2 |
