An object of the present invention is to provide a white laminated polyester film which is excellent in whiteness, slipperiness, ink adhesion, water adhesion, antistatic properties, and scratch resistance. A substrate composed of a white biaxially stretched polyester film in which a polyester resin layer (A layer) containing a white pigment and inorganic particles is laminated on at least one surface of a polyester resin layer (B layer), and the substrate Is a white laminated polyester film comprising a coating layer (C layer) provided on at least one side of the above, wherein the inorganic particles in the A layer have an average particle diameter of 5.0 μm or less and are larger than the average particle diameter of the white pigment. Further, the C layer is provided immediately above the A layer, contains a modified resin, and a high molecular weight antistatic agent having at least one sulfonate group or phosphate group, has a breaking strength of 10 to 100 MPa, and A white laminated polyester film having a surface specific resistance of 1 × 10 6 to 1 × 10 13 Ω / □. |
