DOUBLE-SIDED PRESSURE-SENSITIVE ADHESIVE SHEET AND PRESSURE-SENSITIVE ADHESIVE TYPE OPTICAL MEMBER
摘要:
The present invention provides a double-sided pressure-sensitive adhesive sheet, including at least one pressure-sensitive adhesive layer which has a gel fraction of 10 to 70%, has a storage modulus at 23° C. of 1×105 Pa or less, and has a residual stress after 180 seconds of 3.5 N/cm2 or less, the storage modulus at 23° C. being measured in accordance with a dynamic viscoelasticity measurement and the residual stress after 180 seconds being measured in accordance with a tensile stress relaxation test under conditions of a temperature of 23° C. and a strain of 300%.
