PROBLEM TO BE SOLVED: To obtain a laminated film having excellent uniform coating property of a water-based ink liquid and adhesion to a water-based ink layer by laminating a coat layer on one face of a base material polyester film, making the overall thickness to be a specified value by gravimetric method, and making a wetting index of the surface of one coat layer to be a specified value. SOLUTION: In a laminated film for water-based sublimation ink thermal transfer which is excellent in density gradation in printing at the time of image copying to be represented by a video printer, a coat layer is laminated on one face of a base material polyester film, wherein the overall thickness by gravimetric method is 1.0-5.9μm, and a wetting index of the surface of one coat layer is 40dyn/am or higher. The surface resistivity of one coat layer under 23 deg.C and 50% R.H. condition is less than 10<14> Ω. The wetting index of the surface of the coat layer is set to be 40dyn/cm or higher. For the polyester of the base material, although it is not specially limited, a polyethylene terephthalate is used particularly preferably. |
