Embodiment 1

[0152] (Preparation of composition for forming a hard coat layer)

[0153] Prepare the resin raw material (manufactured by JSR Corporation, trade name " Opstar Z7540", solid content: 56% by weight, solvent: butyl acetate / methyl ethyl ketone (MEK)=76 / 24 (weight ratio)].

[0154] The above-mentioned resin raw material contains dipentaerythritol and isophorone diisocyanate-based polyurethane as the above-mentioned (A) component (ultraviolet curable compound) and silica fine particles (weight average particle diameter: 100 nm or less) with the surface modified by organic molecules as the above-mentioned ( D) component is contained in the weight ratio of (A) component total: (D) component=2:3. The refractive index of the cured film of the above resin raw material was 1.485.

[0155] For 100 parts by weight of the solid content of the resin raw material, add 0.2 parts by weight of a reactive fluorine compound (manufactured by Daikin Industry Co., Ltd., trade name "OPTOOL (register...

Embodiment 2

[0164] The transparent conductive film of this example was obtained by the same method as Example 1 except having formed the said hard-coat layer so that thickness may become 15 micrometers.

Embodiment 3

[0166] The transparent conductive film of this example was obtained by the same method as Example 1 except having made the said reactive fluorine compound into 0.1 weight part, and the said reactive silicon compound into 0.5 weight part.

Abstract

Provided is a transparent conductive film having a hard-coat layer that has sufficient hardness and excellent resistance to both abrasion and contamination. Also provided are a touch panel and an electronic device using the transparent conductive film. The transparent conductive film (10) includes a transparent film base (11), a transparent conductive thin film (12), and a hard-coat layer (13). The hard-coat layer (13) is formed from a hard-coat-forming composition that contains (A) a hardening compound that has an acrylate group and / or a methacrylate group, (B) a reactive fluorine compound, and (C) a reactive silicon compound.

Description

technical field [0001] The present invention relates to a transparent conductive film, an electronic device, and a touch panel. Background technique [0002] Conventionally, as a transparent conductive film, so-called conductive glass in which an indium oxide film is formed on glass is known, but since the base material of conductive glass is glass, it has poor flexibility and workability, and some cannot be used depending on the application. Condition. Therefore, in recent years, in addition to flexibility and processability, various plastic films represented by polyethylene terephthalate (PET) films have been used as base materials for the advantages of excellent impact resistance and light weight. transparent conductive film. [0003] In the case of a transparent conductive film used in a touch panel, since the frequency of direct contact with the conductive film is higher than that of a liquid crystal display device, etc., it is required to achieve both scratch resista...
