  • Polyester film for use as an ink image receiving base film and ink
    Patent number: 6896941
    Abstract: 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 ?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): 0.05?F-1/F-2?0.15 (1) ?wherein (F-1) is an X-ray diffraction intensity on a plane (1{overscore (1)}0) 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.
