Optical double-sided pressure-sensitive adhesive sheet

摘要

The present invention provides an optical double-sided pressure-sensitive adhesive sheet excellent in step absorbability and anti-foaming release property. The invention relates to an optical double-sided pressure-sensitive adhesive sheet including a pressure-sensitive adhesive layer which contains an acrylic polymer A and an acrylic polymer B having a weight average molecular weight of from 1,000 to 30,000, and has a residual stress after 180 seconds of 3.0 N/cm 2 or less, the residual stress after 180 seconds being measured in accordance with a tensile stress relaxation test under the conditions of a temperature of 23 °C and a strain of 300 %.
