Title:
粘着シート、及び、光学部材
Document Type and Number:
Japanese Patent JP6905502
Kind Code:
B2
Abstract:
To provide an adhesive sheet which, in a state of being pasted on an adherend, can keep a low peeling electrification voltage at a time of peeling the adhesive sheet off the adherend, even when exposed to a high temperature during fabrication (production) and transportation, and which has excellent peeling electrification stability after temporal storage at a high temperature.SOLUTION: Provided is an adhesive sheet having on one or both surfaces of a support film an adhesive layer formed from an adhesive composition comprising a (meth)acrylic polymer, a polysiloxane having an oxyalkylene chain, and an ionic compound. After an adhesive surface of the adhesive layer is pasted on a TAC surface at 70°C for one week, a peeling electrification voltage at a peel rate of 30 m/min is less than 0.5 kV (absolute value).SELECTED DRAWING: None
