A method for manufacturing an electrode film includes the steps of laminating a metal layer and a black photoresist layer sequentially on a first main surface of a transparent base material, subjecting the black photoresist layer to patterning in a mesh shape by partially exposing the black photoresist layer and performing development, processing the metal layer into a metal mesh electrode by subjecting the metal layer to etching by using the black photoresist layer subjected to the patterning as an etching mask until the metal layer has a width smaller than a width of a thin wire line constituting a mesh of the black photoresist layer, and covering an upper surface and both side surfaces of a thin wire line constituting a mesh of the metal mesh electrode with the black photoresist layer by heating and softening the black photoresist layer to cause the black photoresist layer softened to flow.

A method of manufacturing a light-transmissive sheet includes: preparing a first support with a first resin in a B-stage being placed on a surface of the first support; preparing a second support; and heating the first resin to convert the first resin from the B-stage to a C-stage, in a state in which the second support is placed on a surface of the first resin.

The present invention is an optically clear, curable adhesive including a polyvinylbutyral, a polyurethane (meth)acrylate, and a photoinitiator. The polyvinylbutyral has a dynamic viscosity of between about 9 and about 13 mPa.Math.s and a polyvinyl alcohol weight percent of less than about 18%. The polyurethane (meth)acrylate includes the reaction product of a diol, at least one diisocyanate, and a hydroxyfunctional (meth)acrylate or an isocyanatofunctional (meth)acrylate. When the optically clear, curable adhesive is placed between two transparent substrates and made into a laminate, the laminate has a haze of less than about 6%, a transmission of greater than about 88% and an optical clarity of greater than about 98% when cured. The optically clear, curable adhesive also has a peel adhesion of at least about 100 g/cm based on ASTM 3330 when cured.
