る防眩性被膜形成用組成物に関する。Detailed Description of the Invention (Field of Industrial Application) The present invention provides anti-glare properties applicable to glass surfaces and transparent synthetic resin plate surfaces with excellent adhesion, scratch resistance, solvent resistance and antistatic properties. The present invention relates to a film-forming composition.

な対応が望まれている。(Background of the invention) In recent years, with the progress of office automation (OA), computers have been introduced into companies and workplaces. The problem of visual impairment of operators who carry out this work has been attracting attention. In order to prevent this operator's visual impairment, the current situation is to manage, regulate, and shorten VDT working hours to minimize this impairment as much as possible. Visual impairment is caused by harmful ultraviolet rays emitted by the display device (cathode ray tube) and external light reflected from the surface of the display device (cathode ray tube), and the reflected light tiring the operator's eyes. This is said to be the cause of the problem, and urgent action is needed.

、電灯や窓等の明るい物体がブラウン管面上に映り、画
面を見すらくし、これも目に悪い影響を与えている。In addition to OA equipment, for example, as seen in home television receivers, external light is uniformly reflected on the cathode ray tube surface, so bright objects such as electric lights and windows are reflected on the cathode ray tube surface, making it difficult to see the screen. , which also has a bad effect on the eyes.

上記の様な問題点を解決しようとするものとしては、反
射面上に微細な凹凸を有する面を形成し。(Prior Art) In an attempt to solve the above-mentioned problems, a surface having fine irregularities is formed on the reflective surface.

ン管表面に直接行なうものとブラウン管前面に配置する
合成樹脂製フィルターの前面に施す場合とがある。There is a technology that suppresses regular reflection and diffuses reflection to create anti-glare. Such surface treatment may be applied directly to the surface of the cathode ray tube, or may be applied to the front surface of a synthetic resin filter placed in front of the cathode ray tube.

。For example, when injection molding a synthetic resin, anti-glare treatment is applied to the surface of the synthetic resin molded product using a mold whose surface has been sandblasted, and when performing casting molding,
The surface of the glass plate to be used as the mold is roughened by sandblasting or corroded with hydrofluoric acid, and cast molding is performed between the roughened glass plate, or by mixing fine particles into synthetic resin paint and painting it. Although there are methods for anti-glare treatment of synthetic resin surfaces, none of these anti-glare treatments are very effective and are economically expensive.

No. 4 discloses an anti-glare coating composition in which an inorganic substance having a specific gravity of 2.5 or less and consisting mainly of Sin, Al, and Ol is mixed in an ultraviolet curable coating in a range of 2% by weight to 30% by weight. In this case, it is necessary to make the particle size of the inorganic material fine and to uniformly disperse it in the ultraviolet curable paint, and sufficient control is required to obtain a dense and uniform anti-glare film. Further, since the film is formed by dispersing inorganic fine particles in the ultraviolet curable paint film, antistatic properties cannot be expected.

A technique has been disclosed in which an uneven coating made of fine silica particles is formed on the front surface of a cathode ray tube glass bulb to provide an anti-glare effect.

However, when this method is applied to synthetic resin plates, although an excellent anti-glare effect can be obtained, the adhesiveness is poor and it easily peels off in the cellophane tape test, making it impossible to put it to practical use.

合がある。By spraying the condensation reaction product of a silyl group-containing vinyl polymer and polysiloxane onto the resin surface, a finely uneven coating is formed on the surface of the synthetic resin plate and cured by heating, further improving resolution and surface properties in some cases. We proposed a method of applying an antistatic agent, ultraviolet rays, or thermosetting surface hardening agent to form a thin film (Japanese Patent Application No. 1983, Japanese Patent Application Laid-open No. 1983-1993). Even in the case of the proposal, the film does not satisfy all of the solvent resistance, scratch resistance, and antistatic properties, and may be insufficient for practical use.

The results showed that by combining alcoholic silica sol and UV-curable surface-curing resin, it can easily achieve adhesion, solvent resistance, scratch resistance, and antistatic properties on glass surfaces and synthetic resin board surfaces. It has been discovered that an anti-glare film-forming composition capable of forming an anti-glare film with excellent properties can be obtained, and the present invention has been completed. Then, by placing a synthetic resin plate treated with the novel anti-glare agent of the present invention on the front of various optical equipment (OA equipment, television cathode ray tubes, etc.), or directly treating the glass surface of the optical equipment. By doing so, visual impairment can be effectively prevented.

A composition for forming an anti-glare film comprising an alcoholic silica sol and a UV-curable surface-curing resin is blended with 2 to 5 parts by weight of the UV-curable surface-curing resin per 1 weight of silica.

ルシリケート。The alcoholic silica sol that can be used is silicon tetrachloride, tetramethyl silicate, etc., which can be obtained by hydrolyzing a hydrolyzable silicon compound such as chlorosilane, carboxysilane, silyl isocyanate compound, or alkyl silicate in an alcohol solvent. , tetraethyl silicate.

媒中で行なわれる。Lower alkyl silicates such as tetra n-propyl silicate and tetra n-butyl silicate are preferred, and methyl silicate, which is a condensation product thereof, is preferred51. Ethyl silicate 40 may be used. These hydrolysis operations are carried out in an alcoholic solvent without a catalyst or in the presence of an acid catalyst according to conventional methods.

Approximately 5% of acetic acid, oxalic acid, and p-toluel are preferably employed. Although the desired product can be obtained even if it is used in excess of 5%,
I can't expect particularly good results.

The solvents used are methanol,
Alcohols such as ethanol, propatool and butanol are preferred.

。特にアルコールに可溶なものが好ましい。There are two types of surface curing resins: ultraviolet curing type and thermosetting type.
Because the heating temperature is limited and the versatility is poor,
An ultraviolet curing type is preferred. As the ultraviolet curing surface curing resin, a wide variety of commercially available resins can be used. Particularly preferred are those soluble in alcohol.

像度、外観も悪くなる。The non-volatile residue in the anti-glare agent is preferably in the range of 5 to 15% by weight. If it is less than 5% by weight, the non-volatile residue in the droplets will decrease, and if the unevenness becomes vague, unevenness will occur, making it difficult to properly prevent the glare. It becomes difficult to obtain a dazzling effect.Furthermore, the adhesion strength decreases, and if it exceeds 15% by weight, the droplets become coarse and the particle size adhering to the surface of the synthetic resin plate increases, further causing unevenness. Also, an appropriate anti-glare effect cannot be obtained, and the resolution and appearance deteriorate.

、緻密で均一なパターンが得られなくなる。The blending ratio of the silica component and the UV-curable surface-curing resin component in the non-volatile residue is such that the UV-curable surface-curing resin component is 2 to 5 parts by weight per 1 part by weight of the silica component. If the amount is less than 2 parts by weight, the adhesion to the surface of the synthetic resin board will be poor, and the solvent resistance and scratch resistance of the coating will be poor. On the other hand, if the amount exceeds 5 parts by weight, the particles adhering to the surface of the synthetic resin plate will become coarse, making it impossible to obtain a dense and uniform pattern.
配合されたシリカゾルは、付着粒子を微細化し、緻密な
パターンにする作用を果すものと思われる。The blended silica sol seems to have the effect of making the adhered particles finer and forming a dense pattern.
また、この場合シリカゾルに基づく静電防止性も失なわ

囲としなければならない。The alcoholic silica sol and the ultraviolet-curable surface-curing resin are blended by mixing them within the above-mentioned blending range. If the type of UV-curable surface-curing resin is difficult to dissolve in alcohol, a solvent that is compatible with both may be mixed, but it must be within a range that does not affect the synthetic resin board.

)に開示した様に以下の操作によりガラス表面や合成樹
脂板表面に吹付け、乾燥することにより、優れた防眩効
果をこれらの表面に付与することができる。The composition for forming an anti-glare film obtained as described above was disclosed in a previous application by the present inventors (Japanese Patent Application No. 1983, Japanese Patent Application Laid-open No. 1988-1991, "Anti-glare treated synthetic resin plate and Its manufacturing method”
), by spraying it onto a glass surface or a synthetic resin plate surface and drying it by the following procedure, an excellent anti-glare effect can be imparted to these surfaces.

しく、入手し安い小口径のものとして0.4m までの
ものが有利であるが、これ以下のものでも差しつかえな
い。Spraying is carried out according to normal operations, and the diameter of the spray nozzle used greatly affects the anti-glare effect. That is, if the aperture is large, the droplets will be coarse and the uneven surface will be rough, which is unfavorable in terms of appearance, and the anti-glare effect will also be uneven. For this reason, the diameter of the nozzle is preferably 0.8+m or less, and a nozzle with a diameter of up to 0.4 m is advantageous as a small diameter that is cheap to obtain, but a diameter smaller than this is also acceptable.
乾燥温度は、樹脂の軟化温度以下の温度でできるだけ高
度であることが好ましいが、一般には50〜60℃の温
度で30分乃至1時間保持すれば十分である。The drying temperature is preferably as high as possible, below the softening temperature of the resin, but generally it is sufficient to maintain the drying temperature at a temperature of 50 to 60°C for 30 minutes to 1 hour.
このようにして防眩剤の吹付けを行ない、ガラス表面や

0 (according to JIS Z 8741), an anti-glare layer having high adhesion, solvent resistance, scratch resistance, and antistatic properties can be obtained.
