Abstract
To provide a laminated polyester film which reduces precipitation of an oligomer even at high temperature, prevents lowering of visibility caused by whitening, occurrence of defects in post-processing and contamination during steps and in a member, always has good antistatic property, and can suppress adhesion and inclusion of a foreign matter.SOLUTION: A laminated polyester film is formed by sequentially laminating a cured resin layer (B), a polyester film and a cured resin layer (A), wherein the cured resin layer (B) contains the following compounds (a), (b) and (c), and the cured resin layer (A) contains a curable silicone resin. (a) One or more kinds of compounds composed of (a1) a polymer obtained by doping a compound composed of thiophene or a thiophene derivative with an anionic compound, and (a2) a self-doped polymer having an anionic group in a compound composed of thiophene or a thiophene derivative, (b) a (meth)acrylic polymer having a styrene structure, and (c) one or more compounds composed of (c1) polyglycerol and (c2) an alkylene oxide adduct to polyglycerol, or derivatives thereof.SELECTED DRAWING: None
