Title:
WRITING FEEL-IMPROVING SHEET
Document Type and Number:
WIPO Patent Application WO/2020/122172
Kind Code:
A1
Abstract:
This writing feel-improving sheet 1 is provided with a base material 11 and a writing feel-improving layer 12 with which a touch pen is brought into contact. When the pen tip of a touch pen having a pen tip with a diameter of 0.5 mm is brought into contact with a surface of the writing feel-improving layer 12 with which said touch pen is to be brought into contact and a load of 200 g is subsequently applied to the touch pen while causing the touch pen to slide linearly at a speed of 1.6 mm/second and maintaining the angle formed by the touch pen and the surface at 45°, the difference between the maximum value and the minimum value of frictional force generated between the pen tip and the surface as measured in an interval from a point at which the sliding distance is 10 mm to a point at which said sliding distance is 100 mm is 80-300 mN. The writing feel-improving sheet 1 makes it possible to suitably reproduce the writing feel experienced when writing on paper with a ballpoint pen.
