Title:
基材レス両面粘着シート
Document Type and Number:
Japanese Patent JP6488819
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a substrate-less double-sided adhesive sheet which can suppress a peeling speed dependency to the minimum, has good antistatic property and releasability, and has low migration property, as a member of a capacitive touch panel.SOLUTION: There is provided a substrate-less double-sided adhesive sheet having different release films having different peeling forces laminated on both sides of an adhesive layer, where the release film has a coating layer containing a conductive compound and a binder polymer laminated on a polyester film, and the release film which has a release layer laminated on the coating layer and has a smaller peeling force has a release layer formed of a coating liquid containing a reactive silicone resin having an alkenyl group and an alkyl group as functional groups, a non-reactive silicone resin having a mass average molecular weight of 400,000 or more and a platinum catalyst, and has a peeling force at 0.3 m/min of 10-20 mN/cm and a peeling force of 60 m/min of 90 mN/cm or less.SELECTED DRAWING: Figure 1
