Title:
EASY STICKING PRESSURE-SENSITIVE ADHESIVE TAPE OR SHEET
Document Type and Number:
WIPO Patent Application WO/2016/059932
Kind Code:
A1
Abstract:
[Problem] To provide a pressure-sensitive adhesive tape or sheet which has fewer limitations during adhesion by virtue of maintaining, over an arbitrary period of time after being brought into contact with the adherend, the function of facilitating removal of fluids such as gases or liquids that enter into gaps between the adherend and the pressure-sensitive adhesive tape or sheet during adhesion. [Solution] This pressure-sensitive adhesive tape or sheet has a convexo-concave shape provided on the support layer or release separator, the height of the convex portions being 45-250μm, the shortest base length of the convex portions being 7-50μm, the shortest base length of the concave portions being 150-5000μm, and the concavity/convexity ratio being greater than 1.00 and no greater than 2.00. Thereby, said shape is transferred to the pressure-sensitive adhesive layer surface to achieve the pressure-sensitive adhesive tape or sheet having an easy-stick function and comprising grooves for facilitating removal of fluids such as gases or liquids that enter into gaps between the adherend and the pressure-sensitive adhesive tape or sheet during adhesion.
