TRANSPARENT DOUBLE-SIDED ADHESIVE SHEET AND IMAGE DISPLAY DEVICE USING SAME

摘要

Provided is a novel transparent double-sided adhesive sheet which has corrosion resistance reliability that an adherend can be prevented from corrosion degradation, is also furnished with antifoaming reliability that foaming at a sticking interface does not occur, and also has an optical reliability that an increase in haze is little even in a hygrothermal environment. Proposed is a transparent double-sided adhesive sheet which is firstly characterized to have an adhesive layer containing a (meth)acrylate ester copolymer containing a carboxyl group-containing monomer as a copolymerization component at less than 2% by mass and silica fine particles having an average particle size of from 4 to 500 nm or less, and secondly characterized in that the adhesive layer is curable by heat or ultraviolet light.
