性の改善に関する。DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to a plastic lens having an undercoat film and an antireflection film formed on its surface, and particularly relates to improving the antistatic properties thereof.
「従来技術およびその問題点」
プラスチックレンズは、軽量で割れにくく、成形が容易

に反射防止膜を形成したものが知られでいる。"Prior Art and its Problems" Plastic lenses are being replaced by glass lenses in various fields because they are lightweight, hard to break, and easy to mold. As such a plastic lens, one in which an antireflection film is formed on a lens substrate is known.

ート膜などを形成したものも提案されでいる。However, plastic lenses have a problem in that they are inferior in scratch resistance compared to glass lenses. For this reason, some proposals have been made in which a hard coat film or the like is formed between the lens substrate and the antireflection layer.

はできなかった。However, since plastic lenses have a high electrical resistance of 1014 to 1016, the plastic lenses have the problem of being charged with static electricity and easily attracting dust. However, it was not possible to improve the adhesion of dust due to static electricity.
このため、プラスチックレンズの材料中に帯電防止剤を

過率か減少し、ざらに屈折率の一様性が模なわれるため
、光学部品には適しでいなかった。For this reason, it is known that antistatic agents are mixed into the material of plastic lenses, which increases moisture absorption, reduces transmittance, and roughly imitates the uniformity of the refractive index. It was not suitable for parts.
［発明の目的」
本発明の目的は、反射防止性および耐擦傷性を有すると

出していることを特徴とする。"Structure of the Invention" The plastic lens according to the present invention has an undercoat film and an antireflection film formed on a plastic lens substrate, and the undercoat film is made of a material having an electrical resistance I of 1010 Ω or less, and The undercoat film is exposed at an edge portion of the plastic lens substrate.

外部に逃げることができ、帯電防止゛ｉも得られる。As described above, in the present invention, the undercoat film provides scratch resistance, and the antireflection film also provides antireflection properties. Since the undercoat film is made of a material with an electrical resistance of 1010 Ω or less, static electricity passes through this undercoat film, and from the periphery of the lens where the undercoat film is exposed, the mirror body that holds the lens is exposed. It can escape to the outside through the passage, and antistatic properties can also be obtained.

とによりコーティングすることができる。According to a preferred embodiment of the present invention, as the undercoat film, an ethyl silicate resin, for example, Colcoat Nl03J (In product name, manufactured by Nippon Colcoat Co., Ltd.) is used. In this case, the resin is coated on the lens substrate. After coating with a spinner, it can be coated by drying with hot air at 80° C. for about 2 hours.

きる。Further, the antireflection film can be formed by coating an inorganic material such as magnesium fluoride, silicon dioxide, or cerium trifluoride by means such as vacuum deposition. In this case, the antireflection film may be composed of multiple layers of films having different refractive indexes. Note that when forming the antireflection film, the undercoat film can be exposed by covering the peripheral edge of the lens substrate with a mask or the like.

ことにより、アンダーコート膜１３が形成されている。This plastic lens 11 has a lens substrate 12 made of injection molded polymethyl methacrylate, and the surface of this lens substrate 12 is coated with ethyl silicate resin Colcoat Nl03J (trade name, manufactured by Nippon Colcoat Co., Ltd.). An undercoat film 13 is formed by applying a thickener and drying at 80° C. for 2 hours.

保持されでいる。The plastic lens 11 is then inserted into the cylindrical mirror body 15 and the ribs on the inner wall 1 as shown in FIG. M2.
A ring 16 is screwed onto the tip of the mirror body 15, and the plastic lens 11 is held between the rib 15a and the ring 16, thereby being held on the mirror body 15.

Therefore, no charging occurs, and the adhesion of dust and the like due to static electricity can be prevented. Further, in this plastic lens 11, the undercoat film 13 provides scratch resistance, and the antireflection film 14 provides antireflection properties.
