Title:
TRANSPARENT CONDUCTIVE SHEET, TOUCH PANEL MODULE AND TOUCH PANEL DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/158577
Kind Code:
A1
Abstract:
In order to suppress deterioration of electric characteristics and to achieve superior transparency, durability and moisture resistance in an adhesive layer, this transparent conductive sheet comprises an adhesive layer which is contacts a conducting layer and which contains an acrylic copolymer which has a weight average molecular weight Mw exceeding 100,000 and less than or equal to 2,000,000 and contains, as a copolymer monomer component, hydrophobic monomers selected from alkyl methacrylates having a linear or branched alkyl group of 1-9 carbon atoms, alkyl(meth)acrylates having a cyclic alkyl group of 5-9 carbon atoms and alkyl(meth)acrylates having an alkyl group of 10-20 carbon atoms. The total blending ratio of the hydrophobic monomers in the copolymer monomer component of the acrylic copolymer is greater than or equal to 35 mass% of the total mass of the acrylic copolymer, and the haze value is less than or equal to 1.0 when the thickness of the adhesive layer is 100 µm; this touch panel module and touch panel device use said transparent conductive sheet.
