PURPOSE: To obtain a colored film which cannot be manufactured so far by forming an oriented polyester film made of at least three or more layers in such a manner that the inner layer is a layer containing dye and the outermost layer contains no dye and specific condition formulae can be simultaneously satisfied. CONSTITUTION: An automotive window bonding laminated polyester film is an oriented polyester film made of at least three or more layers in such a manner that the outermost layer of a layer for forming exposed two surfaces is a layer containing no dye, and the inner layers except the outermost layer contains dye. The polyester for forming the inner and outermost layers of the film simultaneously satisfies the relations represented by formulae I to III [where IA, IB are the viscosities of the polyester composition for forming the inner and outer layers, dA, dB are the thicknesses (μm) of the inner and outer layers, and TA, TB are visible ray permeability (%) of the inner and outer layers].
