Abstract: [Problems] Objects include providing a cover film for testing which can be well fixed to a substrate having a groove and in which a pressure sensitive adhesive does not invade into the groove, providing a testing member comprising the cover film for testing, and providing a method of manufacturing the cover film for testing.
[Solution] The cover film for testing (1, 2) comprises a base material (10) and a pressure sensitive adhesive layer (20) laminated on one surface side of the base material (10). The cover film for testing (1, 2) has a region in which the pressure sensitive adhesive layer (20) does not exist in the plan view.

Abstract: A writing feel improving sheet comprising a base material and a writing feel improving layer with which a touch pen is brought into contact, wherein when a touch pen having a pen tip of 0.5 mm diameter is used to bring the pen tip into contact with a surface of the writing feel improving layer with which the touch pen is brought into contact and the touch pen is then linearly slid at a speed of 1.6 mm/second while applying a load of 200 g to the touch pen and maintaining an angle formed between the touch pen and the surface at 45°, a difference between a maximum value and a minimum value of frictional force generated between the pen tip and the surface is 80 mN or more and 300 mN or less, wherein the frictional force is measured between a point at which a sliding distance is 10 mm and a point at which the sliding distance is 100 mm. The writing feel improving sheet makes it possible to well reproduce the writing feel experienced when writing on paper with a ballpoint pen.

Abstract: [Problems] Objects include providing a cover film for testing which can be well fixed to a substrate having a groove and with which a material that constitutes an adhesive layer does not invade into the groove and a specimen can be easily stored in the groove, providing a testing member including the cover film for testing, and providing a method of manufacturing the cover film for testing.
[Solution] The cover film for testing (1) comprises a base material (10), a hydrophilic coating layer (20) laminated on a surface of the base material (10), and an adhesive layer (30) partially laminated on a surface of the hydrophilic coating layer (20) opposite to the base material (10), whereby the cover film for testing (1) has a region in which the adhesive layer (30) is absent and the hydrophilic coating layer (20) is exposed.
