  • Patent number: 9321247
    Abstract: A transparent film, the back-face of which has excellent resistance to scratch and printability, and a surface protection film which has such a transparent film are provided. A transparent film 10 has a substrate layer 12 formed of a transparent resin material, and a back-face layer 14 with a thickness of 1 ?m or less provided on a first face 12A thereof. A percent change in coefficient of friction ?? is less than 10% for the transparent film 10 when the percent change is determined from a coefficient of friction ?50 of the back-face layer after being conserved at 50° C. and 15% RH for three days and a coefficient of friction ?80 of the back-face layer after being conserved at 80° C. and 80% RH for three days, with an absolute value of difference between the two coefficients of friction |?80??50| being divided by the smaller value of the two coefficients of friction.

  • Patent number: 9305680
    Abstract: The present invention relates to a transparent conductive film which is excellent in dotting property under a heavy load and excellent in bending resistance. Provided is a transparent conductive film, comprising a flexible transparent base; and a transparent conductive layer formed on the flexible transparent base and including a crystalline indium/tin composite oxide, wherein a compressive residual stress of the transparent conductive layer is 0.4 to 2 GPa.
