<p>The present invention provides a polyester laminated film which comprises a transparent layer (1) and a delustered layer (2) laminated at least on one side face of the transparent layer. The transparent layer is formed by a biaxially stretched polyester film mainly composed of polyethylene terephthalate, while the delustered layer is made of an at least uniaxially stretched polyester film which is mainly composed of a polyethylene terephthalate copolymer containing, as a copolymer composition, 1 to 20 mol.% of the delustered layer of H &lparstr& OCH2CH2 &rparstr& OH or H &lparstr& OCH2CH2 &rparstr& n-1 O-X-O &lparstr& CH2CH2 &rparstr& n-1H (wherein n is an integer from 2 to 140, and X represents <CHEM> and which also contains inert inorgantc particles (2 min ) of 0.3 to 20 microns diameter in an amount 3 to 40% by weight of the delustered layer. Film according to the present invention as described above is roughened on the surface. and has excellent writability and transcribability by pencils, ink, indian ink, etc., combined with an excellent transparency, and therefore, is very useful for use as tracing films and the like.</p> |
