Document Type and Number:
WIPO Patent Application WO/2024/106096
Kind Code:
A1
Abstract:
The following is provided as an adhesive sheet that has a low refractive index and excellent flexibility. An adhesive sheet according to the present invention is formed from an adhesive composition that contains an acrylic copolymer and a radical-polymerizable compound (x). The refractive index of the adhesive sheet is no more than 1.470. The shear storage modulus ratio (G'(-30°C)/G'(80°C)) between the shear storage modulus (G'(-30°C)) of the adhesive sheet at -30°C and the shear storage modulus (G'(80°C)) of the adhesive sheet at 80°C as measured by dynamic viscoelasticity measurement in the shear mode at a frequency of 1 Hz is 1–65.
