Problems solved by technology

[0007] However, in the conventional technology, it is not possible to evaluate according to these three senses, so the sense of recording is insufficient.
With the surface material of Patent Document 1, since the outermost surface is formed of a hard coat layer, the sliding feeling is not good
In addition, the surface does not have unevenness (texture) such as paper, so there is a problem of insufficient roughness
The surface material of Patent Document 2 has a rough feeling due to the unevenness of the surface, but there is a problem that the sliding feeling is not satisfactory and the concave feeling is insufficient.
The surface material of Patent Document 3 has a concave feeling due to the use of soft synthetic resin, but the sliding feeling is not ideal
In addition, since no texture is formed on the surface, there is a problem of insufficient roughness
[0008] Therefore, it is desired to develop a surface material with a good recording feeling that satisfies the three senses of sliding, sinking, and roughness with a good balance, but there is no surface material that can fully satisfy the sliding feeling.

Embodiment 1

[0061] 80 parts by weight of urethane acrylate (manufactured by Shin Nakamura Chemical Industry Co., Ltd., trade name: NK オリゴ U-108A), 10 parts by weight of pentaerythritol triacrylate, 20 parts by weight of acrylic acid and 0.1 part by weight of polysiloxane 5 parts by weight of polystyrene microparticles with an average particle diameter of 10 μm were added to a mixed liquid composed of alkanes (Byk-chemie, trade name: BYK-300), and the resin liquid for the surface layer was prepared by sufficiently stirring.

[0062] The resin liquid was coated on a base material (triacetylcellulose film) having a thickness of 100 μm by a roll coater to form a resin coating layer having a uniform thickness of 20 μm. The resin coating was cured by irradiating electron beams (150 KeV, 5 Mrad) with an electron curtain type EB device (manufactured by ESI). Then, a solution containing an acrylic adhesive was applied on the surface opposite to the base material, and dried to form an adhesive laye...

Embodiment 2

[0064] To 40 parts by weight of polyethylene glycol #600 diacrylate, 10 parts by weight of trimethylolpropane triacrylate, 50 parts by weight of dimethylacrylamide, 0.1 part by weight of polysiloxane compounds (Shin-Etsu Chemical Industry ( Co., Ltd., trade name: KF-351A) and 5 parts by weight of 2-hydroxyl 2-methyl-1-phenyl-propane-1-ketone (photopolymerization initiator) in the mixed solution of adding 5 parts by weight average Acrylic fine particles with a particle diameter of 14 μm were then thoroughly stirred to prepare a surface layer resin solution.

[0065] The resin liquid was coated on a base material (polyethylene terephthalate film) having a thickness of 100 μm by a roll coater to form a resin coating layer having a uniform thickness of 20 μm. Under a nitrogen atmosphere, irradiate ultraviolet light (3J / cm2) with a 120W high-pressure mercury lamp (manufactured by Nippon Battery Co., Ltd.) 2 ) to cure the resin coating. Then, a solution containing an acrylic adhes...

Embodiment 3

[0067] A resin liquid for a surface layer was prepared by fully stirring a liquid mixture consisting of 100 parts by weight of polyol acrylate having a hydroxyl value of 50, 20 parts by weight of hexylene diisocyanate, and 7 parts by weight of silica-based fine particles. This resin solution was coated on a base material (polyethylene terephthalate film) having a thickness of 100 μm by a roll coater to form a resin coating layer having a uniform thickness of 30 μm. It was dried at 100° C. for 10 minutes to cure the resin coating. Then, a solution containing an acrylic adhesive was applied on the surface opposite to the base material, and dried to form an adhesive layer, whereby the surface material for a pen input device of Example 3 was produced. The pen input device was manufactured by crimping and sticking the surface material for the pen input device on the surface of the liquid crystal display with the touch input device at normal temperature. Various evaluations were pe...

Abstract

The invention provides a surface member attached to the indication surface of a pen-input device. The surface member comprises a substrate, and a surface layer disposed on the substrate. The surface layer has a dynamic friction coefficient and a static friction coefficient that are adjusted. The dynamic friction coefficient and static friction coefficient that are adjusted, which are measured by moving an input-pen at a speed of 10 cm / sec while contacting the input-pen with the surface of the surface layer under a weight of 200 g in a 20 °C and 50% relative humidity atmosphere, are 0.02-0.5 and 0.4-1.5, respectively.

Description

technical field [0001] The present invention relates to a surface material for a pen input device having a good recording feeling and a pen input device using the same. Background technique [0002] Generally, a pen input device is installed on the front of various displays such as a liquid crystal display, and performs information input operations based on a contact position signal detected when the surface is touched with an input pen. If a pen input device is used, subtle operations such as input of continuous linear figures such as curves and straight lines can be easily performed with the input pen, and a large amount of information can be input even on a relatively small drawing. Since the input operation of writing on the display with a stylus is easy to become a habit, the use range of pen input devices has been widely and rapidly expanded by portable information terminals such as electronic notebooks and multimedia machines. [0003] Surface materials used in conve...
