<p>PROBLEM TO BE SOLVED: To provide a laminated polyester film excellent in transparency, suppression of an iris-like pattern (interference fringes) or less visibility of the pattern when a hard coat layer is laminated, adhesiveness (moisture heat-resistant adhesiveness) with a hard coat layer under high temperature and high humidity conditions, adhesiveness (boiling-resistant adhesiveness) when immersed in hot water, and hot water-resistant transparency when immersed in hot water.SOLUTION: The laminated polyester film has a resin layer (X) on at least one surface of a polyester film. The resin layer (X) is formed by using a resin composition (α) comprising a polyester resin (a) having a glass transition temperature Tg of 105°C or higher and 135°C or lower, a polyester resin (b) having a glass transition temperature Tg of 65°C or higher and 95°C or lower, a melamine compound (c), and a carbodiimide compound (d). A variation in film haze before and after a boiling treatment,ΔHz (ΔHz=(film haze after the boiling treatment)-(film haze before the boiling treatment)), is less than 5.0%.</p> |
