の障害や埃りが付着しやすい問題があった。Conventionally, when a display device such as a cathode ray tube, a light emitting diode, a liquid crystal display device (for example, a TV, a clock, a calculator, etc., is used under daylight or irradiation light, a transparent plate that covers the surface and front surface of the display device. External light (such as the above-mentioned sunlight or illumination light) is reflected on the surface of the display to cause a dazzling glow, resulting in poor display screen contrast, making it difficult to read the display content. Due to the charging of the surface, the surface of the transparent synthetic resin plate mounted on the front surface of the display device is also charged, the charge is not attenuated, and there is a problem that an obstacle such as discharge to a human body in use and dust are likely to be attached.

問題がある。(1) A method of applying a surfactant (antistatic agent) to the surface of the coating film (2) A method of adding and mixing a surfactant (antistatic agent) to the paint (3) Adding and mixing conductive powder to the paint Method [Problems to be solved by the invention] In the surface roughening by the methods of (1) and (2), the surface unevenness is deep or only a rugged shape is obtained, and the light transmittance becomes significantly low. Also, since the light is diffused too much, there is a problem that the screen of the display device is dark and the display contents are blurred and difficult to read. Further, since the external light is randomly diffused on a rough surface, it has an effect of suppressing so-called glare, but has no effect of attenuating the amount of reflected light,
There is a problem that it has no effect of preventing charging. In the case of a transparent synthetic resin plate, it is more likely to be scratched and has a problem in chemical resistance.

するという製造上の問題がある。In the surface roughening by the method of (3), the surface unevenness obtained by physically roughening the surface in addition to the above (1) is a deep or gradual unevenness as in the above (1), so that the surface is transparently coated. When applied with a substance, there is a manufacturing problem that the shape and performance of the resulting uneven surface change considerably due to a slight difference in the film thickness of the transparent coating substance.

いという問題がある。In the method of (4), in addition to the above (1), white turbidity due to a slight difference between the refractive index of the matting agent and the refractive index of the coating binder, sedimentation of the matting agent, unevenness of unevenness due to aggregation, and variation are likely to occur. There is.
また、帯電を防止する方法については以下のような問題
点がある。In addition, there are the following problems with the method of preventing charging.
（１）の方法では、帯電防止効果は一時的であり、流水
等で洗うことなどで効果が消失するという問題がある。The method (1) has a problem that the antistatic effect is temporary and the effect disappears by washing with running water or the like.

ある。In the method (2), many of the surfactants bleeding on the surface of the coating film exhibit an antistatic effect, and many of the surfactants in the coating film hardly cause bleeding on the coating film surface. There are many temporary effects similar to the above (1), and there is a problem that the adhesion of the coating film is adversely affected.
（３）の方法では、効果は恒久的であるが、導電性粉末

して読み取る用途には問題がある。In the method of (3), the effect is permanent, but if the amount of the conductive powder added is small, it is not effective. Therefore, it is necessary to add a large amount. Therefore, the diffused light beam inevitably increases and the light transmittance is increased. Is reduced. Further, since the surface is likely to be finely roughened by the conductive powder, the diffused light beam is further increased, and there is a problem in the use for transmitting and reading.

るが、艶消し能の点からは意味がない。In the present invention, having fine surface irregularities and having a matting ability means that the center line average surface roughness (abbreviated as Ra) defined by JIS B-0601 is 0.01 to 5 μm.
The surface gloss is 60 ° specular gloss defined by JIS Z-8741, standard black glass is 93.0%, and the value when applied to a transparent methacrylic resin cast plate (3 mm thickness) is 10 to 140%.
Furthermore, when the center line average surface roughness is less than 0.01μ, there is almost no matting ability, and the glossiness is close to a smooth surface (more than 140% by the above-mentioned glossiness measurement method), resulting in unevenness. There is no point in applying the coating, and when the center line average surface roughness exceeds 5 μ, the surface irregularities become rough and the surface gloss does not change substantially, so it is technically possible. It has no meaning in terms of matting ability.

Must be ~ 1/500. When the height of the convex portion is less than 0.1 μm, the effect as an antireflection molded article is reduced. 2.
When it is larger than 0 μm, the resolution of the transmitted image is lowered. When the diameter of the convex portion is smaller than 10 μ, the resolution of the transmitted image is lowered. If the diameter is larger than 100 μm, the antireflection effect is lowered. Further, the resolution of the transmitted image is largely influenced by the ratio of the height / the diameter of the convex portion which is mainly formed, and the resolution is lowered when the ratio of the height / the diameter is larger than 1/30.
If it is less than 1/500, the antireflection effect is reduced.
