る。2. Description of the Related Art Resin plates are usually very easily charged, and when left indoors, they absorb floating dust and impair the appearance, or become a source of contamination in clean rooms. I do. Various antistatic resin plates have been proposed to prevent this. In order to impart antistatic performance to a resin plate, it is effective to lower the resistance value on the surface of the resin plate. As a measure, it is known that the resin surface is made hydrophilic so that water molecules are easily adsorbed. In practice, a resin having a hydrophilic functional group such as polyethylene glycol is kneaded during the production of the resin plate. That is being done. However, the resistance value of the surface of the resin plate obtained by this method is only about 10 11 Ω, and the half life of the charged electric charge is about several seconds to several tens of seconds.
In order to improve such disadvantages in the prior art, there has been proposed a method of reducing the surface resistance by providing a layer in which conductive fine particles having a particle size sufficiently smaller than the wavelength of light are dispersed on the resin surface ( See JP-B-63-33778). In this method, tin oxide fine particles doped with antimony are used as the conductive fine particles.
The resistance value of the surface of the resin plate obtained by this method is about 1
0 8 Ω, and the half life of the charged electric charge is 1 second or less.

防止性の樹脂板を提供することにある。However, such a conventionally known antistatic resin plate has a problem in transparency, and particularly tends to increase fogging. In particular, when the haze value is 2% or more, the impression that the haze is large in appearance is strongly received. An object of the present invention is to solve such a problem,
An object of the present invention is to provide an antistatic resin plate having a high transparency and a small haze value, which is useful as a partition of a clean room or a front plate of a display device.

脂板の透明性が確保される。The resin which can be used as the substrate in the present invention may be any resin having transparency, and specific examples thereof include methacrylic resin, polycarbonate, and vinyl chloride resin. On a substrate made of such a transparent resin, an antistatic layer containing 60 to 80% by weight of fine particles of tin oxide doped with antimony is usually provided via an adhesive layer such as a hot melt adhesive. The average particle size of tin oxide is required to be 0.2 μm or less. In that case, since the size of the fine particles is sufficiently smaller than the wavelength of visible light, scattering of visible light is reduced, and a transparent antistatic resin plate is used. Transparency is ensured.

くない。When the content of tin oxide fine particles is large, the distance between the particles becomes small and the surface resistance can be reduced. However, when the content exceeds 80% by weight, the haze value increases and the impression that the haze is large is large. To receive it. On the other hand, when the content of the tin oxide fine particles is less than 60% by weight, the surface resistance value of the transparent antistatic resin plate exceeds 1 × 10 9 Ω, and the half life of the charge becomes 1 second or more, which is not preferable. .

It is necessary not to exceed the value obtained by adding the percentage. If the haze value is equal to or greater than the value obtained by adding 0.8% to the haze value of the transparent resin substrate, the resin plate becomes undesirably cloudy.

支えない。The transparent antistatic resin plate of the present invention is suitably produced by a roll transfer method. For example, a release layer, an antistatic layer and an adhesive layer are laminated on a resin film such as polyethylene terephthalate (hereinafter sometimes abbreviated as PET) in this order, and the resulting laminated film is applied on a transparent resin substrate. After laminating with a pressure roll,
By peeling off only the laminated film, the intended transparent antistatic resin plate can be manufactured. The antistatic layer may be provided on one side of the transparent resin substrate, or may be provided on both sides.

In order to reduce the thickness to less than 1.5 μm, the thickness is preferably set to 1.5 μm or less. In order to uniformly provide such a thin antistatic layer on a transparent resin substrate, it is better to transfer the one provided on the resin film to the transparent resin substrate than to provide the antistatic layer directly on the resin plate.

Since the treatment at a higher temperature is easier than that of a transparent resin substrate such as methacrylic resin, it is advantageous to provide the antistatic layer on a resin film. Transferring to a substrate is advantageous.
In the present invention, the antistatic layer may be formed of a hard coat paint having a crosslinked structure as a matrix, and heat curing, ultraviolet curing, or the like is suitably used for curing this layer.

The coating was applied and dried at about 1 μm, and then an acrylic pressure-sensitive adhesive was applied thereon and dried. The film thus obtained is combined with a 3 mm-thick polymethyl methacrylate (hereinafter sometimes abbreviated as PMMA) resin substrate, and pressed using a roll heated to 150 ° C., and then the PET film is peeled off.

Using this transfer film, transfer was performed to a PMMA resin substrate in the same manner as in Example 1 to obtain an antistatic plate. The haze value and the surface resistance value were the same as those in Example 1, and the abrasion resistance was such that the change in the haze value (ΔH) before and after rubbing 100 times with steel wool was a very low value of 0.2 to 0.3%.
