Problems solved by technology

[0005] Resistive film type touch panels are excellent in cost and precision, but due to the two-piece structure of the film (electrode) and glass, the transmittance is lower than other methods, so the outer part (frame) of the effective screen is wider than that of the effective screen. In addition, since the film (electrode) is pressed down to short-circuit the structure, it has the disadvantages of a narrow operating temperature range and a poor change over time.

Embodiment 1

[0118] (Preparation of aqueous dispersion)

[0119] Add 1000 parts of butyl acrylate, 50 parts of acrylic acid, 23 parts of mono[poly(oxypropylene) methacrylate] phosphate (the average degree of polymerization of propylene oxide is 5.0), and 0.34 parts of 3-methacryloyloxy Triethoxysilane (manufactured by Shin-Etsu Chemical Co., Ltd., KBM-503) was used as a raw material and mixed to obtain a monomer mixture. Next, 13 parts of Aqualon HS-10 (manufactured by Daiichi Kogyo Pharmaceutical Co., Ltd.) as a reactive emulsifier and 360 parts of ion-exchanged water were added to 600 parts of the monomer mixture prepared in the above ratio, and a homogenizer (special Kikka Kogyo Co., Ltd.) was stirred at 7000 rpm for 3 minutes to prepare a monomer emulsion.

[0120] Then, 200 parts and 350 parts of ion-exchanged water in the monomer emulsion prepared above were put into a reaction vessel equipped with a condenser tube, a nitrogen gas introduction tube, a thermometer, a dropping funnel,...

Embodiment 2

[0134] The addition amount of the ammonia water of concentration 10% in the (preparation of water dispersion type acrylic adhesive) in embodiment 1 is changed from 3 parts to 10 parts, the drying in the (formation of adhesive layer) of embodiment 1 Except that the conditions were changed from 130° C. for 10 minutes to 90° C. for 10 minutes, it was implemented in the same manner as in Example 1, and a transparent conductive film with an adhesive layer was produced.

Embodiment 3

[0136] Except that the addition amount of ammonia water with a concentration of 10% in Example 1 (preparation of water-dispersed acrylic adhesive) is changed from 3 parts to 0.5 parts, it is implemented in the same way as Example 1 to make a tape adhesive layer of transparent conductive film.

Abstract

A pressure-sensitive adhesive layer of the invention for transparent conductive film has a thickness of 10 mum to 100 mum, and is made from a water-dispersible acryl-based pressure-sensitive adhesive that is an aqueous dispersion containing a water-dispersible (meth)acryl-based polymer and a water-soluble basic component, wherein the water-dispersible (meth)acryl-based polymer comprises 100 parts by weight of an alkyl(meth)acrylate with an alkyl group of 4 to 14 carbon atoms, as a monomer unit, and 1 to 8 parts by weight of a carboxyl group-containing monomer as a copolymerized monomer unit, and the pressure-sensitive adhesive layer contains 200 ng to 500,000 ng of the water-soluble basic component per 1 cm2 as determined by measurement of the pressure-sensitive adhesive layer. The pressure-sensitive adhesive layer can have satisfactory durability in a high-temperature or high-temperature, high-humidity environment and can suppress corrosion in a high-temperature, high-humidity environment.
