Embodiment 1

[0101] 100 parts by mass of dipentaerythritol hexaacrylate (manufactured by Shin-Nakamura Chemical Industries, NK Ester A-DPH) as a polyfunctional (meth)acrylate (expressed in terms of solid content. Hereinafter, the same applies to other components.); 4.3 parts by mass of 1-hydroxycyclohexyl phenyl ketone (manufactured by BASF Corporation, Ilgakyua 184) as a photopolymerization initiator; silica microparticles (manufactured by Fuji Silicone Chemical Co., Ltd., Cyclohobic 702); average particle diameter: 4.1 μm, CV value 48%, amorphous) 11 parts by mass; 0.01 parts by mass of polydimethylsiloxane (manufactured by Toray Dou Corning Co., SH28) and silica nanoparticles (manufactured by Nissan Chemical Industry Co., Ltd., MIBK) as a leveling agent -ST, average particle diameter: 10 nm) 8.3 parts by mass were mixed to obtain a coating composition. This coating composition was diluted with propylene glycol monomethyl ether to prepare a coating liquid having a solid content concentra...

Embodiment 2

[0110] Except having changed the compounding quantity of a leveling agent into 0.14 mass part, and having formed an anti-glare hard-coat layer, it carried out similarly to Example 1, and produced the anti-glare hard-coat film.

Embodiment 3

[0112] Except having changed the compounding quantity of a leveling agent into 0.70 mass part, and having formed an anti-glare hard-coat layer, it carried out similarly to Example 1, and produced the anti-glare hard-coat film.

Abstract

The invention provides an anti-dazzling hard coating film by which the writing feel of a stylus is good, and attached fingerprints can be easily wiped. To solve the problem, the anti-dazzling hard coating film 1 is provided. The anti-dazzling hard coating film for a touch panel comprises a substrate film 11 and an anti-dazzling hard coating 12 arranged on the surface of one side of the substrate film 11,for the surface of the anti-dazzling hard coating, when a hard-felt-core stylus with a nib diameter of 0.5 mm scans at a speed of 100 mm / min and under the pressure of the weight of 150 g, An initial movement value (A) and a sliding value (B) of the nib resistance (mN) satisfies the relation of the following formula (a); meanwhile, (a) 0<=the initial movement value (A)-the sliding value (B), the oleic acid contact angle of the surface of the anti-dazzling hard coating 12 is below 45 degrees.

Description

technical field [0001] The present invention relates to an antiglare hard coat film for a touch panel using a stylus. Background technique [0002] In recent years, in various electronic devices, touch panels that are both display devices and input devices are widely used. The surface of the touch panel is usually provided with a hard coat film having a hard coat layer in order to prevent damage. In addition, various displays including touch panels reflect light incident from the outside and sometimes make it difficult to see the displayed image. Therefore, an anti-glare hard coating with an anti-glare function may be used by roughening the surface of the hard coating film. coating film. [0003] Among the above-mentioned touch panels, besides finger input, there is also a touch panel that sometimes uses a stylus pen for input. Using a stylus pen is thinner than a finger, and thus enables high-precision input operations. However, generally, the display module of the touch...
