DOUBLE-SIDED PRESSURE-SENSITIVE ADHESIVE SHEET, LAMINATE COMPRISING COMPONENT MEMBER FOR IMAGE DISPLAY DEVICE, KIT FOR LAMINATE FORMATION, AND USE OF DOUBLE-SIDED PRESSURE-SENSITIVE ADHESIVE SHEET

摘要

Provided is a double-sided pressure-sensitive adhesive sheet for application to flexible members which has high folding endurance and neither breaks nor peels off even in a flex test conduced under conditions close to those in practical use environments.The double-sided pressure-sensitive adhesive sheet is substrateless, and is characterized by having been formed from a pressure-sensitive adhesive composition containing a (meth)acrylic ester (co)polymer (A) and by having a glass transition temperature (Tg), which is the tanδ peak temperature for dynamic viscoelasticity, in the range of -50°C to -20°C, a storage modulus G', as measured at a frequency of 1 Hz and a temperature of 100°C, in the range of 2.0×10³ to 3.0×10⁴ Pa, and a thickness of 10-150 μm.
