Title:
ADHESIVE TAPE
Document Type and Number:
WIPO Patent Application WO/2022/230935
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an adhesive tape that achieves both excellent adhesive power and holding power. The adhesive tape according to the present invention has an adhesive agent layer. When a small-angle X-ray scattering measurement (SAXS) is performed on the adhesive agent layer at 23°C and 100°C, a scattering vector q has a scattering peak within a range of 0.05-1.0 nm-1. When a dynamic viscoelasticity measurement is performed on the adhesive agent layer at a measurement frequency of 1 Hz, the loss tangent tanδ exhibits peaks, and the temperature of a peak observed at the highest temperature among the peaks is at most 45°C.
