f! Anti-reflection films are used that are made of appropriate combinations of inorganic materials.
しかし、前者の場合は充分な反射防止特性が得られず、
また後者の場合は以下のような欠点を有している。However, in the former case, sufficient antireflection properties cannot be obtained;
Furthermore, the latter case has the following drawbacks.

れない。(1) The antireflection film made of the above-mentioned inorganic substance is usually made by vacuum deposition, but since transparent synthetic resin has low heat resistance, the deposition temperature cannot be raised, and if it is deposited at a low temperature, it will not absorb light. An antireflection film with sufficient frequency cannot be obtained.
（２）ｄ明合成樹詩と前記無倒物質とでは、熱膨張率が

。(2) The coefficient of thermal expansion is large between Meisynthetic tree and the above-mentioned non-inverting material; ! 4, the anti-reflection film is likely to crack due to changes in the environmental temperature, and the film is likely to peel off.
（３） 前記無機物質は、透明合成樹脂との密着性が
悪く、光分な耐久性を有する反射防止膜が得られない。(3) The inorganic substance has poor adhesion to the transparent synthetic resin, making it impossible to obtain an antireflection film that has durability against light.
（４）以上のような理由により、耐擦傷性にすぐれた反

を特徴とする。That is, according to the present invention, a layer of polyorganosiloxane resin having a film thickness of α5 μm to 50 μm is provided on an optical component made of transparent synthetic resin, and an antireflection film and L”′ (made of zirconium oxide (ZrO2)) are formed on the layer. layer and silicon dioxide (81
A total of four or more layers are provided alternately with the layers consisting of 02).

膜が形成できるため、透明合成樹脂製光学部品の反射防
止膜としてすぐれた特性を有するものである。By alternately layering four or more layers consisting of z r o and layers consisting of B i 03, it is possible to suppress the total inverse iR ratio of the long surface of the transparent synthetic resin optical component to less than 1 inch, An antireflection film with extremely excellent antireflection properties can be obtained, and the ZrO2 and 8102 have IJ! ; Since a film with sufficient strength can be formed even when deposited at high temperature, it has excellent properties as an antireflection film for optical parts made of transparent synthetic resin.

に密着させ。In addition, by interposing a layer of polyorganosiloxane resin between the transparent synthetic resin optical component and the antireflection film, this copper fat layer acts as a buffer material, and the crankshaft due to the difference in coefficient of thermal expansion. In addition to preventing this from occurring, the transparent synthetic resin optical component and the antireflection film are tightly adhered to each other.

問題が生ずるため、上述の範囲が望ましい。While it is possible to improve durability and abrasion resistance, if the thickness of the polyorganosiloxane sebaceous membrane is thinner than 15 μIn, its function as a buffering material will not be sufficient and it will prevent the occurrence of cracks. In addition, if the thickness exceeds 50 μm, it is difficult to make the film thickness uniform @VC, which causes the problem of deterioration of antireflection properties. A range of is desirable.
