PRESSURE-SENSITIVE ADHESIVE LAYER FOR TRANSPARENT CONDUCTIVE FILM, TRANSPARENT CONDUCTIVE FILM WITH PRESSURE-SENSITIVE ADHESIVE LAYER, TRANSPARENT CONDUCTIVE LAMINATE, AND TOUCH PANEL

摘要

This pressure-sensitive adhesive layer for transparent conductive film has a thickness of 10 to 100µm, and is formed from an aqueous-dispersion type acrylic pressure-sensitive adhesive which consists of an aqueous dispersion that comprises both a water-dispersible (meth)acrylic polymer and a water -soluble basic component, said water-dispersible (meth)acrylic polymer containing 1 to 8 parts by weight of copolymerized monomer units derived from a carboxyl-containing monomer relative to 100 parts by weight of the main monomer units derived from an alkyl (meth)acrylate wherein the alkyl moiety has 4 to 14 carbon atoms. Further, the pressure-sensitive adhesive layer contains 200 to 500000ng of the water-soluble basic component per square centimeter (cm2), as determined on the basis of the pressure -sensitive adhesive layer. The pressure-sensitive adhesive layer for transparent conductive film exhibits satisfactory durability even under high-temperature conditions and even under high-temperature and high-humidity conditions, and can inhibit corrosion even under high-temperature and high-humidity conditions.
