manufacture example 1

[0113] (preparation of polycyclohexyl methacrylate)

[0114] In three 300ml flasks with stirrers, 75g of methyl isobutyl ketone was added, and the temperature was raised to 70° C. under the condition of purging with nitrogen. After reaching 70° C., 25 g of cyclohexyl methacrylate and 0.81 g of a polymerization initiator PERBUTYLPV (manufactured by NOF Co., Ltd., 71% Shellsol dilution) were added dropwise in three portions each over an hour. After completion of the dropwise addition, polymerization was further carried out at 70° C. for 3 hours, then the temperature was raised to 80° C., and polymerization was continued for 3 hours. After cooling, the polymerization is terminated. Then, it was added dropwise to methanol and reprecipitated to obtain polycyclohexyl methacrylate. As a result of gel permeation chromatography (GPC) measurement, the mass average molecular weight was 26,000, and the number average molecular weight was 9,000.

Embodiment 1

[0116] (composition for forming antiglare layer)

[0117] Hexafunctional Acrylic Urethane

[0118] (manufactured by Nippon Synthetic Chemical Industry Co., Ltd., Purple Light UV-7600B) 60 parts by mass

[0119] 10 parts by mass of trimethylolpropane triacrylate

[0120] 30 parts by mass of cyclohexyl methacrylate of Manufacturing Example 1

[0121] Cross-linked polystyrene microparticles

[0122] (manufactured by Soken Chemical Co., Ltd., SX-130H; average particle size: 1.3 μm) 3 parts by mass

[0123] 3 parts by mass of 1-hydroxycyclohexyl phenyl ketone

[0124] 150 parts by mass of methyl isobutyl ketone

[0125] The composition for forming the anti-glare layer was applied as a transparent substrate on a PET film with a thickness of 100 μm by a roll coater, and dried at 80° C. for 2 minutes so that the dry film thickness was 5 μm . Thereafter, it was cured by irradiating ultraviolet light (cumulative light intensity: 400mJ / cm2) with a 120W high-pressure mercury lamp (...

Embodiment 2

[0128] A surface material for a display was produced in the same manner as in Example 1 except that 5 parts by mass of cross-linked polystyrene was used as the composition for forming the antiglare layer. The Sm of the obtained antiglare layer was 150 μm, Ra was 0.16 μm, Rz was 1.2 μm, the 60-degree gloss value was 89%, and the haze value of the surface material for a display was 9.0%.

Abstract

The present invention relates to a surface material which is arranged on the surface of the display and is used by the high-precision display, and the surface material includes an anti-dazzle layer which is directly arranged on the transparent base material or indirectly arranged with a functional layer. The anti-dazzle layer has concave-convex formed on the whole surface and the average distanceof the concave-convex ranges from 20 to 300mu m, the surface energy of the anti-dazzle layer is from 30 to 70mN / m and the haze value of the display used surface material is from 3 to 50%.

Description

technical field [0001] The present invention relates to a surface material for a display provided on the surface of a display, and a high-definition display and a high-definition touch panel provided with the above-mentioned surface material. The displays include: image displays for personal computers, televisions, mobile phones, etc., and touch screen displays for car electronic navigators, automatic teller machines (ATMs), etc.; and displays for glass cabinets, plastic cabinets, etc. monitor. Background technique [0002] In the above-mentioned display, if the light from the outside is not diffused and reflected on its surface (display surface), the image will be reflected here, making it difficult to see the internal image. Anti-glare film for external light. [0003] However, if the surface of the display is touched by the skin of hands, fingers, etc., skin traces such as fingerprints and fingerprint traces (hereinafter referred to as "fingerprint traces") formed by bi...
