ADHESIVE SHEET FOR OPTICAL USE

摘要

Provided is an adhesive sheet for optics comprising a structure in which a first adhesive layer and a second adhesive layer are stacked. The first adhesive layer has a glass transition temperature of -50 to -30°C and modulus of 0.3 x 10^5 to 0.6 x 10^5 Pa. The second adhesive layer has a glass transition temperature of -20 to -10°C and modulus of 0.7 x 10^5 to 1.0 x 10^5 Pa. The adhesive sheet of the present invention has excellent step absorptivity and weather resistance.
