  • Patent number: 10399310
    Abstract: A resin film 10 comprising a polyimide-based polymer is disclosed. The resin film 10 has a tensile elastic modulus of 4.0 GPa or more. In a bending test where the resin film 10 is repeatedly folded into a U-shape until the distance between the resin film faces opposed to each other reaches 3 mm, and unfolded, the number of times of folding the resin film 10 until the resin film 10 fractures is more than 100000.
    Type: Grant
    Filed: July 21, 2016
    Date of Patent: September 3, 2019
    Assignees: SUMITOMO CHEMICAL COMPANY, LIMITED, INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTE

  • Publication number: 20170329062
    Abstract: To improve an optical film containing a polyimide-based polymer and the like and used for a front plate of a flexible device member, in terms of improvement of hygroscopic characteristics and achievement of high transparency, less coloring, and satisfactory ultraviolet absorption. Disclosed is an optical film containing a polyimide-based polymer and/or polyamide and an ultraviolet absorbent. A light transmittance of the optical film is not more than 5% at 380 nm and not less than 80% at 420 nm.
