Document Type and Number:
WIPO Patent Application WO/2022/039108
Kind Code:
A1
Abstract:
Provided is an adhesive tape having strong adhesive force and high holding force with respect to an adherend in which a non-woven fabric is used. According to the present invention, there is provided an adhesive tape comprising a substrate and an adhesive agent layer provided on the substrate. The substrate is a non-woven fabric. The adhesive agent layer includes an adhesive agent. The adhesive agent contains a styrene-isoprene-styrene block copolymer and an adhesion-imparting agent. The softening point of the adhesion-imparting agent in the softening point test method (ball-and-ring method) stipulated in JIS K22076.4 is 100°C or higher. The styrene-isoprene-styrene block copolymer has a styrene content of 14-30 mass% and a coupling rate of 30-90 mass%. The mass ratio of the adhesion-imparting agent to the styrene-isoprene-styrene block copolymer is 0.5-1.5.
