Title:
OPTICAL PRESSURE-SENSITIVE ADHESIVE COMPOSITION, OPTICAL PRESSURE-SENSITIVE ADHESIVE SHEET, IMAGE DISPLAY DEVICE, AND INPUT/OUTPUT DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/132780
Kind Code:
A1
Abstract:
An optical pressure-sensitive adhesive composition which comprises (A) a hydrogenated block copolymer, (B) a first compatibilizing agent, and (C) a second compatibilizing agent, wherein the hydrogenated block copolymer (A) comprises a hard segment constituted of a polymer of an aromatic vinyl monomer and a soft segment constituted of a polymer of a conjugated diene monomer, the first compatibilizing agent (B) has the property of being compatible with the hard segment and has a softening point of 80ºC or higher, and the second compatibilizing agent (C) has the property of being compatible with the soft segment and is liquid at ordinary temperature (23ºC). The optical pressure-sensitive adhesive composition gives a pressure-sensitive adhesive layer which has a relative permittivity of 1-3.5.
