The present invention relates to an oriented laminatednpolyester film for pasting on car windows, comprising at leastnthree layers including intermediate layer(s) beingnincorporated with a dye, which laminated polyester filmnsatisfies the following conditions simultaneously:n the ratio of the dye concentration (%) in the outermostnlayers on both sides (CA) to the dye concentration (%) in thenintermediate layer (CB) being not more than 0.5, the ratio of the sum of the thicknesses (µm) of thenoutermost layers (DA) to the overall thickness (µm) of thenwhole layers (DZ) being 0.02 to 0.8, the heat shrinkage (%) in the machine direction andntransverse direction of the film when heat-treated at 180°Cnfor 5 minutes (SMD and STD) being 1.0 to 5.0% and not morenthan 2.0%, respectively, the center line average roughness (µm) of the filmnsurface (Ra) being 0.005 to 0.05 µm, and the film haze (H, %) being not more than 5%. n This laminated film is free from the problem ofncontamination by the dye during manufacture thereof, showsnexcellent workability when applied curved glass of annautomobile, and also has excellent transparency. |
