Problems solved by technology

In this case, when the size of the glass substrate is increased, it takes a long time to form a film, and there is a problem of lowering production efficiency.
In addition, since the protective film formed by this method has extremely poor adhesion to the substrate or insufficient hardness, scratches and peeling are likely to occur during transportation or transportation, and the reliability of the touch panel may decrease. The problem

Embodiment

[0115] Hereinafter, synthesis examples and examples are disclosed, and the present invention is more specifically described, but the present invention is not limited to the following examples.

[0116] Manufacture of (co)polymers

Synthetic example 1

[0118] In a flask equipped with a condenser tube and a stirrer, 5 parts by mass of 2,2'-azobis(2,4-dimethylvaleronitrile) and 200 parts by mass of diethylene glycol methyl ethyl ether were charged first. Then, 40 parts by mass of glycidyl methacrylate, 18 parts by mass of styrene, 20 parts by mass of methacrylic acid, and 22 parts by mass of N-cyclohexylmaleimide were charged, and then replaced by nitrogen, and then slowly stirred . The temperature of the solution was raised to 70° C., and the temperature was maintained for five hours to obtain a polymer solution containing the copolymer (A-1). The solid content concentration of the obtained polymer solution was 33.1% by mass. The number average molecular weight of the obtained polymer was 7,000 (the number average molecular weight is a polystyrene-equivalent molecular weight measured using GPC (gel permeation chromatography) HLC-8020 (manufactured by TOSOH Co., Ltd.)). In addition, the molecular weight distribution (Mw / Mn) ...

Synthetic example 2

[0120] In a flask equipped with a condenser tube and a stirrer, 5 parts by mass of 2,2'-azobisisobutyronitrile and 200 parts by mass of diethylene glycol methyl ethyl ether were charged first. Next, 40 parts by mass of glycidyl methacrylate, tricyclic methacrylate [5.2.1.0 2，6 ] 35 parts by mass of decan-8-yl ester, 20 parts by mass of methacrylic acid, and 5 parts by mass of 1,3-butadiene were further replaced by nitrogen, and then slowly stirred. The temperature of the solution was raised to 80° C., and the temperature was maintained for five hours to obtain a polymer solution containing the copolymer (A-2). The solid content concentration of the obtained polymer solution was 33.3% by mass. The number average molecular weight of the obtained polymer was 6,500. In addition, the molecular weight distribution (Mw / Mn) was 2.

Abstract

The present invention relates to a ray-sensing resin composition for forming a protective film and a method for forming the protective film. The resin composition for the protective film has a high transparence, an excellent adhesiveness with a transparent conductive film and an excellent crock resistance. The ray-sensing resin composition for forming the protective film of a touch panel is characterized in that the resin composition contains (A) caustic solubility resin, (B) ethylene series unsaturated compound having one carboxyl in a molecule, and (C) ray-sensing polymerization initiator.

Description

technical field [0001] The present invention relates to a radiation-sensitive resin composition which is extremely good in forming a protective film of a transparent conductive film in a touch panel and a method for forming the same. Background technique [0002] In terms of touch panels, there are resistive film type, electrostatic capacitive type, ultrasonic type, optical type, electromagnetic induction type, etc. Up to now, the resistive film type has been the mainstream in terms of price. However, the resistive film type has disadvantages such as many misoperations, and the manufacturers who adopt the electrostatic capacitance type tend to increase. In terms of electrostatic capacity, a transparent conductive film such as ITO (Indium Tin Oxide) film is formed on the substrate. In order to protect this transparent conductive film, it must be formed on the transparent conductive film with abrasion resistance and good adhesion to the substrate. Protective film (refer to Ja...
