The object of the present invention is to provide a laminated film excellent in light resistance, scratch resistance, transparency, dimensional stability and adhesion to a hard coating layer. The present invention is a laminated film comprising a base material layer, an easily adhering layer and a hard coating layer, wherein the easily adhering layer is formed on the base material layer and the hard coating layer is formed on the easily adhering layer, and further wherein(1) the base material layer is formed of a polyester resin formed from naphthalenedicarboxylic acid as a main dicarboxylic acid component and ethylene glycol as a main glycol component,(2) the hard coating layer has an ultraviolet absorbing function and has a pencil hardness of H or higher on the hard coating layer surface, and(3) said laminated film has a variation (.DELTA.b*) of less than 2.0 between transmittance b* values obtained before and after a 300 hours' xenon arc test of said laminated film.
