Problems solved by technology

[0006] On the other hand, in the projected capacitive touch panel, the color difference between the part where the transparent electrode pattern is formed and the part where the transparent electrode pattern is not formed becomes large due to the difference in optical reflection characteristics, and the transparent electrode pattern is reflected when modularized. The problem of the so-called "light and shadow visible phenomenon" on the screen
In addition, between the substrate and the transparent electrode, or between the visibility-improving film (OCA: Optical Clear Adhesive, Optical Clear Adhesive) for bonding the cover glass used for modularization to the transparent electrode pattern and the transparent electrode pattern There is a problem that the intensity of reflected light increases and the transmittance of the screen decreases

Embodiment

[0167] Hereinafter, although an Example and a comparative example demonstrate this invention more concretely, this invention is not limited to the following Example.

[0168] [Preparation of binder polymer solution]

Synthetic example A1

[0170] 85.7 parts by mass of 1-methoxy-2-propanol (manufactured by Daicel Chemical Industry Co., Ltd.) was charged in advance in the reaction vessel, and the temperature was raised to 80°C. On the other hand, 46 parts by mass of cyclohexyl methacrylate, 2 parts by mass of methyl methacrylate, 52 parts by mass of methacrylic acid, and 10 parts by mass of an azo-based polymerization initiator (manufactured by Wako Pure Chemical Industries, Ltd., V-601) were mixed to obtain a mixed solution. This mixed solution was dripped into the said reaction container of 80 degreeC over 2 hours under nitrogen atmosphere. After dripping, it was made to react for 4 hours, and the acrylic resin solution was obtained.

[0171] Next, 2.5 parts by mass of hydroquinone monomethyl ether and 8.4 parts by mass of tetraethylammonium bromide were added to the above-mentioned acrylic resin solution, and then 32 parts by mass of glycidyl methacrylate was added dropwise over 2 hours. After dropping, react...

Synthetic example A2

[0173] Add 62 parts by mass of propylene glycol monomethyl ether and 62 parts by mass of toluene to a flask equipped with a stirrer, a reflux cooler, an inert gas inlet, and a thermometer, raise the temperature to 80°C under a nitrogen atmosphere, and keep the reaction temperature at 80°C The compound shown in Table 1 and 1.5 parts by mass of 2,2'-azobis(isobutyronitrile) were uniformly added dropwise at ±2°C over 4 hours. After the dropwise addition, stirring was continued at 80° C.±2° C. for 6 hours to obtain binder polymer solution A2 (solid content: 45 mass %) having a weight average molecular weight of 30,000 and an acid value of 156.6 mgKOH / g.

Abstract

This transfer-type photosensitive film comprises a supporting film and a first resin layer that is provided on the supporting film; and the first resin layer contains a photo-polymerizable compound having a tricyclodecane skeleton or a tricyclodecene skeleton and an acyl phosphine oxide-based photo-polymerization initiator.

Description

technical field [0001] The present invention relates to a transfer type photosensitive film, a method for forming a cured film pattern, a cured film, and a touch panel. Background technique [0002] Liquid crystals are used in large electronic equipment such as personal computers and televisions, small electronic equipment such as car navigation, mobile phones, smart phones, and electronic dictionaries, and display equipment such as OA (Office Automation, Office Automation) and FA (Factory Automation, Factory Automation) equipment, etc. Display elements and touch panels (touch sensors). [0003] Various types of touch panels have been put into practical use, and in recent years, use of projected capacitive touch panels has been advanced. Generally, in a projected capacitive touch panel, a plurality of X electrodes and a plurality of Y electrodes perpendicular to the X electrodes form a two-layer structure in order to represent two-dimensional coordinates composed of an X ax...
