の着色コート膜に関するものである。Detailed Description of the Invention: a. Technical Field The present invention relates to a colored coating film for optical products, and more specifically, in colored glasses such as sunglasses and fashion glasses, the coloring is not caused by a single colored glass, but by a coating film. This invention relates to a colored coating film for optical products such as eyeglasses produced by the above method.

ＣｅＯ２＊ Ｃｒ２０３ 、 Ｆｅ２０：ｌを成分とし

上の不良にはならないが、経時的膜の劣化には不安が残
される。Although it was an excellent product to be used in place of the high refractive index layer of a transparent multilayer antireflection film due to its stable film composition, it had the following problems. These are many fine pinholes that are thought to be mainly caused by strong internal stress. Since these pinholes are difficult to see with the naked eye, they do not cause any visual defects, but there remains concern about the deterioration of the film over time.
上記ピンホールは、スライドプロジェクタ−では、膜面

れ、膜が欠如していることが明らかとなった。With a slide projector, the pinholes appeared as clouding on the film surface, and when observed with a microscope, they were found to be a collection of light spots. Furthermore, analysis by SEM and XMA revealed that the shape was amorphous and that no coating film component was detected at the light spot, only the substrate glass component was detected, indicating that there was no film.

夏である。The presence of such holes generally allows the penetration of moisture and reactive gases, which damages the film and underlying glass and causes deterioration in quality over time such as burning, peeling, and weakening of the film strength. This was a problem. Especially when it comes to items such as eyeglasses, which are constantly exposed to dirty air, it's early summer.

ート薬品を蒸着することにより、従来の特性。In view of the C0 objective and above, the present invention utilizes conventional colored coating chemicals, namely CeO2, Cr203? Conventional properties were achieved by adding a small amount of Yb20 to a coating chemical containing Fe2C3 and vapor depositing the colored coating chemical.
即ち多層反射防止膜の高屈折率層への適用性や、膜組成
の安定に重要な昇華性等を維持したまま。In other words, the applicability of multilayer antireflection coatings to high refractive index layers and sublimation properties, which are important for stabilizing the film composition, are maintained.

3 = 100: 8.25: 3.0: 1
The melting point of 0-30%vvb2o3 is 2250°C, which is approximately 300°C higher than other components, and in order to maintain the deposition rate, it is necessary to increase the evaporation source power as well as the content of Yb2O3. Vapor deposition rate required for production efficiency for a substrate located at a distance of 800 μm from the evaporation source is λ/4/2

Deposition speed cannot be achieved unless the power is increased considerably; at high power, sublimation properties are lost and melting begins.

発された。The drug having the above composition is a powder mixture of 9. The particles were pressed at Q8t/cd to form particles of approximately 3-13 particles, and then heated and evaporated with an electron beam.

The multilayer antireflection film was made of alternating layers of low refractive index layers L (MgF2) and high refractive index layers 11 (the above-mentioned constituent materials) on a substrate glass with a refractive index of 1.60.

コート膜面の曇りは１通常具られる膜の微細構造に原因

６従来の薬品では後者の曇りが問題となった。しかし、
Ｙｂ２ ｏ、をＣｅＯ２に対し１０％、２０％、３０
％ｔｉｔ添加した本発明の構成薬では、いずれも上述の
ような曇りの発生はみられなかった。Table 1 e, The cloudiness of the coating film surface in Examples can be caused by two conditions: 1. One is light scattering caused by the fine structure of the film, and the other is grain-like clouding due to large defects such as those mentioned here. The latter haze was a problem with certain 6 conventional chemicals. but,
Yb2 o, to CeO2 10%, 20%, 30
%tit of the constituent drugs of the present invention, no occurrence of cloudiness as described above was observed.

とによって増大し、その結果起こったものと判断された
が、その立場からＹｂ２Ｏ３を添加した場合に全層コー
トでも発生しないことは、 Ｙｂ２０３が応力を緩和す
る作用があったと考えられる。With conventional chemicals, no grain-like clouding was observed in up to 4 layers of coating from the base layer, but a large amount of clouding occurred in all 1J"r coats, indicating that internal stress caused the layers to overlap. However, from this standpoint, the fact that it did not occur even with full-layer coating when Yb2O3 was added suggests that Yb203 had a stress-relieving effect.
上記構成での薬品で作られたコート膜の光学定数は従来
のｖｂ２ｏコを含まないものと大差なく。The optical constants of the coating film made with chemicals in the above configuration are not much different from those of conventional coatings that do not contain VB2O.

分光反射率Ｒは第１図にみる如く良再現であり、膜組成
の安定性が伺える。Therefore, the structure of the multilayer antireflection coating is similar to that of conventional coatings, with the exception of a slight difference in film thickness, and the results obtained show the same concentration as that obtained with conventional chemicals, and its spectral transmittance T and spectral reflectance R. As shown in Figure 1, the reproduction is good, indicating the stability of the film composition.
ｆ、効果
従来の薬品にｖｂ２ｏコを少量加えることにより、それ
を用いた多層膜にはピンホールが発生しないことがわか
ったが、このことはまた次の結果をもたらした。f. Effect It was found that by adding a small amount of VB2O to conventional chemicals, no pinholes were generated in the multilayer film using it, but this also brought about the following results.
第１は膜強度の向上である。即ち従来の薬品を使用した
多層膜には、ピンホールが無数に発生していた為に、傷
はそれをきっかけとして入りやすかったのに対し１本発
明の薬品による多層膜では。The first is an improvement in film strength. That is, in the multilayer film using conventional chemicals, there were countless pinholes, which were likely to cause scratches, whereas in the multilayer film using the chemicals of the present invention.
その欠点がないために一層膜強度が向上した。Since there is no such drawback, the film strength is further improved.
第２はピンホールの発生を抑えられたことによって、水
分や反応性ガスの膜内への侵透を防ぎ、厳しい環境にお
いても膜および光学特性を劣化せしめないものと期待出
来ることなどである。Second, by suppressing the generation of pinholes, it is possible to prevent moisture and reactive gases from penetrating into the film, and it is expected that the film and optical properties will not deteriorate even in harsh environments.
尚、着色反射防止膜構成は、従来と同様の７層構成で、
同じ濃度、同じ分光反射特性が得られ。The colored anti-reflection coating has the same 7-layer structure as before.
The same concentration and spectral reflection characteristics can be obtained.
また従来の薬品の特徴である昇華性がそこなわれず、第
１図の再現にもみられるように膜組成の安定性もあり、
残薬の繰返し使用など従来の薬品の長所は全て維持され
るものである。In addition, the sublimation property, which is a characteristic of conventional chemicals, is not impaired, and the film composition is stable, as seen in the reproduction of Figure 1.
All the advantages of conventional medicines, such as repeated use of leftover medicines, are maintained.
