PRESSURE-SENSITIVE ADHESIVE SHEET FOR OPTICAL MEMBER, COVER PANEL-TOUCH PANEL MODULE LAMINATE, AND INPUT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive sheet for an optical member, by which high reliability can be achieved by controlling whitening caused under high-humidity/temperature, and rework of an adherend is easy when a failure of sticking together or the like occurs.;SOLUTION: A pressure-sensitive adhesive sheet for an optical member has a peelable pressure-sensitive adhesive layer, and the peelable pressure-sensitive adhesive layer comprises a pressure-sensitive adhesive composition containing an acrylic copolymer and azide polymer having a repeating unit shown by general formula (A). In the general formula (A): R¹ represents an alkyl group, which has a carbon number of 1 and may be replaced, and may exist or not exist; X¹ and X² may be the same as or different from each other, and at least one thereof represents an azide-containing group shown by ZN₃ (Z represents a bivalent alkyl group); X¹ and X², which are not the azide-containing group, represent hydrogen atoms, alkyl groups or alkoxy groups; R² and R³ represent hydrogen atoms, alkyl groups or alkoxy groups; and p represents an integer.;COPYRIGHT: (C)2014,JPO&INPIT
