Document Type and Number:
WIPO Patent Application WO/2021/153390
Kind Code:
A1
Abstract:
Provided is an adhesive tape that has a high degree of biomass, sufficient adhesive strength and is extremely easy to break down. This adhesive tape has an adhesive agent layer containing a polyester resin and is characterized by having a degree of biomass of at least 80 wt% in the adhesive agent layer, a gel percentage of less than 40 wt% in the adhesive agent layer, and an adhesive strength to a stainless steel sheet of 4–15 N/20 mm. As a result of the present invention an adhesive tape can be provided that has a high degree of biomass, sufficient adhesive strength, and is extremely easy to break down after the adhesive tape has been used for a long period under high temperature or high humidity conditions.
