<p>A laminated film comprising (A) an aromatic polyester film; and (B) a hydrophilic coating layer which is present on at least one side of the aromatic polyester film (A) and has a surface energy of at least 54 dyne/cm, the coating layer comprising (a) 50 to 80 % by weight of a copolyester which contains a dicarboxylic acid component having a sulfonate group in an amount of 1 to 16 mol% of the total of all dicarboxylic acid components and has a secondary transition point of 20 to 90 DEG C, (b) 10 to 30 % by weight of poly(alkylene oxide) having a number average molecular weight of 600 to 2,000, and (c) 3 to 25 % by weight of fine particles having an average particle diameter of 20 to 80 nm, based on the total of components (a), (b) and (c). The above laminated film is useful as a transparency for an overhead projector and a recording paper for an ink jet printer.</p> |
