Title:
ADHESIVE LAYER, OPTICAL FILM HAVING ADHESIVE LAYER, OPTICAL LAMINATE, AND IMAGE DISPLAY DEVICE
Document Type and Number:
Japanese Patent JP2020114914
Kind Code:
A
Abstract:
To provide an optical laminate that has reworkability with respect to a transparent conductive layer, corrosion resistance, and high durability.SOLUTION: An optical laminate has an optical film having an adhesive layer, stuck to a transparent conductive layer 6 of a transparent conductive substrate. The optical film having the adhesive layer has an optical film and adhesive layers 5, 10. Each adhesive layer contains a (meth)acrylic polymer (A), which contains, as monomer units, carboxyl group-containing monomers of 15 wt.% or less in all the monomer components forming the (meth)acrylic polymer (A), and a silicon compound (B), which is one or more silicon compounds selected from the group consisting of alkoxysilane compounds and organopolysiloxane compounds having an acidic group or an acid anhydride group derived from an acidic group and having no polyether group in the molecule, and/or a hydrolytic condensate thereof. The adhesive layer satisfies the conditions of the resistance value change ratio represented by general formula (1): R250/Ri≤3.0 (1).SELECTED DRAWING: Figure 1
