Document Type and Number:
WIPO Patent Application WO/2016/181691
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a double-sided adhesive tape for an optical film, the double-sided adhesive tape being used to fix an optical film and having high constant-load peelability with respect to an adherend, high strain and stress resistance, and tape workability. The present invention is a double-sided adhesive tape for fixing an optical film, for fixing an optical film to an adherend, wherein the double-sided adhesive tape for fixing an optical film has an adhesive layer containing a cross-linking agent and an acrylic polymer obtained by living radical polymerization and having a weight-average molecular weight of 500,000 to 1,800,000 and a molecular weight distribution (Mw/Mn) of 1.05 to 2.5, and the adhesive layer has a displacement recovery rate of 30 to 90% measured in a micro-shear displacement measurement test in which a load of 200 g at a temperature of 80°C was applied for 3 minutes and then the load was removed, and the displacement recovery rate was measured 3 minutes later.
