<P>PROBLEM TO BE SOLVED: To provide a flame-retardant laminated polyester film for a flat cable and a flat cable using the same, having high flame retardancy, thermal fusion properties, and dimensional stability under high temperature, without unevenness for flame retardancy and thermal fusion properties, and excellent in flex resistance. <P>SOLUTION: The flame-retardant laminated polyester film for a flat cable includes a laminate structure containing (A) a layer mainly composed of copolymer polyester containing specific carboxy-phosphinic acid component and (B) a layer containing 95% by weight or more of polyester component on the basis of weight of the layer, with a content of the carboxy-phosphinic acid component of 10% by weight or more and 40% by weight or less on the basis of weight of the layer (A), the layers (A) and (B) being the same main polyester component, and moreover, intrinsic viscosity of the polyester used for the layer (A) is to be 0.63dl/g or more and 1.0dl/g or less. <P>COPYRIGHT: (C)2011,JPO&INPIT |
