<p>PURPOSE: A double-sided pressure-sensitive adhesive tape is provided to have a small thickness change, to restrain the degradation of accuracy of touch detection due to a transparent conductive film. CONSTITUTION: A double-sided pressure-sensitive adhesive tape comprises a solvent type acrylic copolymer, has a total thickness of 150microns or less, has weight increase of 10-150 weight% after impregnation to artificial adenomas for 3 days at 55 deg. C. After attaching transparent conductive film, When A is an adhesion(N/5mm) after 72 hours in 50% RH at 23 deg. C, 180 degrees separation direction, and a tensile rate of 300 mm/minutes and B is an adhesion after impregnating the adhesive tape to artificial adenomas at 55 deg. C for 72 hours, B/A is 0.4 or more.</p> |
