<P>PROBLEM TO BE SOLVED: To provide a white laminated polyester film excellent in printing property which has a low rate of thermal shrinking and being reduced in the curling property of a base material sheet after printing inhibited by improving the cushioning properties of the base material sheet and raising printing sensibility. <P>SOLUTION: The white laminated polyester film comprises a polyester layer (A) and a polyester layer (B), wherein the polyester layer (A) contains inorganic particles which has a mean particle size of 0.01-3 μm and has pimples on the polyester layer (A) surface having 200 μm or more in an amount below 20 pieces/m<SP>2</SP>, and the polyester layer (B) contains a non-compatible resin with a polyester of 11 to 40 wt.% relative to the total weight of the above-mentioned (polyester B) layer, and the white laminated polyester film further comprises a thermoplastic polyester elastomer having a melting point in the range of 160°C-230°C in an amount of 2 to 25 wt.%. <P>COPYRIGHT: (C)2007,JPO&INPIT |
