POLYESTER FILM FOR INK IMAGE RECEIVING SUBSTRATE AND INK IMAGE RECEIVING SUBSTRATE

摘要

A white biaxially oriented polyester film for use as a base film for receiving an ink jet printer image and a base film for receiving an ink jet printer image which satisfy the following requirements (1) to (4): (1) the content of titanium oxide particles having an average particle diameter of 0.1 to 0.5 mu m in the polyester film is 5 to 20 wt%; (2) the polyester film has an average glossiness of 65 to 95 %; (3) the polyester film has an X-ray diffraction intensity ratio (F-1/F-2) represented by the following formal (1): <DF NUM="(1)">0.05 </= F-1/F-2 </= 0.15 </DF> wherein (F-1) is an X-ray diffraction intensity on a plane (110) parallel to the surface of the film and (F-2) is an X-ray diffraction intensity on a plane (100) parallel to the surface of the film; and (4) the polyester film has a static friction coefficient of 0.3 to 0.6. The base film for receiving an ink jet printer image of the present invention is excellent in adhesion, glossiness, opacifying properties and transportability.
