Title:
PRESSURE-SENSITIVE ADHESIVE COMPOSITION, PRESSURE-SENSITIVE ADHESIVE SHEET, AND OPTICAL MEMBER
Document Type and Number:
WIPO Patent Application WO/2018/056167
Kind Code:
A1
Abstract:
The present invention provides a pressure-sensitive adhesive composition, a pressure-sensitive adhesive sheet formed using the pressure-sensitive adhesive composition, and an optical member to which the pressure-sensitive adhesive sheet has been applied. The pressure-sensitive adhesive sheet, even after having been applied to an optical member such as a polarizing plate and stored in a high-temperature environment, can achieve the stability over time of antistatic properties and stripping electrification voltage. The pressure-sensitive adhesive composition of the present invention is characterized by comprising a tacky polymer and an ionic-group-containing silicone represented by formula (1). (R1 to R4 may be the same or different and each include any of a C1-10 alkyl group, alkoxy group, aryl group, alicyclic group, fluoroalkyl group, and ionic group, provided that one or more of R1 to R4 include an ionic group; and n is an integer of 0-100.)
