ー蒸着膜等の方法が知られていた。Conventionally, a method such as a color vapor deposition film using interference colors in which chromium, zinc sulfide, and chromium are sequentially configured by physical vapor deposition such as vacuum vapor deposition, sputtering, and ion plating in cover glass for watches and the like has been known.
従来のカラー蒸着膜を施したカバーガラスの場合、硫化
亜鉛を使用している等の点から密着強度が悪く剥離しや
すい等の問題があった。それに膜厚コントロールが厳し
い為、色調のバラツキがでやすい等の欠点があった。In the case of a conventional cover glass provided with a color vapor deposition film, there is a problem in that the adhesion strength is poor and peeling is likely due to the fact that zinc sulfide is used. In addition, since the film thickness control is strict, there are drawbacks such as easy variations in color tone.
そこで、本発明は上記のような問題点、欠点を解決する
ため、密着強度が高く干渉色変化が少ない膜厚コントロ
ールがしやすい、バラツキの少ないカラー蒸着膜とした
カバーガラスを得ることを目的としている。Therefore, in order to solve the above problems and drawbacks, the present invention aims to obtain a cover glass having a color vapor deposition film with high adhesion strength, small interference color change, easy film thickness control, and less variation. There is.
上記問題点を解決するために、本発明は内面の一部に蒸

組合わせにより密着強度が高いカラー蒸着膜を得るもの
である。In order to solve the above problems, the present invention is a cover glass in which a vapor deposition film is formed on a part of the inner surface by a physical vapor deposition method such as vacuum vapor deposition, sputtering and ion plating, and a chromium-only layer of chromium and chromium oxide. A color vapor deposition film having high adhesion strength is obtained by a combination of constitutions.
上記のような構成によるので、蒸着膜の密着強度が高く
なり、また従来の硫化亜鉛に比べると干渉色の変化が少
ないため、膜厚コントロールがしやすく、カバーガラス
の上面から見たときの色調のバラツキが少なくなる。With the above configuration, the adhesion strength of the vapor deposition film is high, and the change in interference color is less than that of conventional zinc sulfide, which makes it easier to control the film thickness and provides a color tone when viewed from the top of the cover glass. Variation is reduced.
以下、実施例に基づいて更に詳細に説明する。 Hereinafter, further details will be described based on examples.
実施例１ 第１図は本発明の一実施例の断面図である。Embodiment 1 FIG. 1 is a sectional view of an embodiment of the present invention.
カバーガラス１を酸およびアルカリで洗浄した後、真空

し、更に第２の酸化クロム被膜４を約400Å、反射膜と
して、第２のクロム被膜５を約1500Å形成した。After the cover glass 1 was washed with acid and alkali, it was set on the jig provided in the vacuum evaporation system and 3 × 10 -6 Torr
After evacuating to a vacuum, the first chromium oxide film 2 is formed as a transparent thin film with a thickness of about 400Å, the first chromium film 3 is formed with 100Å, and the second chromium oxide film 4 is formed as a reflection film with a thickness of about 400Å. Chrome coating 5 of about 1500 Å was formed.
このように形成すると、第２のクロム被膜５の厚みが15
00Åと厚いため遮光性になり、第２の酸化クロム被膜４

１の中央部は時計の文字板なとが見えるように透明にな
っており、周辺の蒸着部において見える色調が装飾的な
効果を有する。When formed in this way, the thickness of the second chromium coating 5 is 15
Since it is as thick as 00Å, it has a light-shielding property.
The incident light becomes reflected light at the boundary surface 5a with the second chromium coating 5 and functions as a reflecting film. On the other hand, since the other films were thin, they were translucent, and when the cover glass 1 was viewed from above, the vapor deposition part appeared black due to the interference color. The central portion of the cover glass 1 is transparent so that the dial plate of a watch can be seen, and the color tones visible in the surrounding vapor deposition portion have a decorative effect.
この膜の密着強度テストにおいては剥離はなかった。ま
た同じバッチ内のサンプルにおいてバラツキが少ないも
のであった。No peeling occurred in the adhesion strength test of this film. In addition, there were few variations among the samples in the same batch.
実施例２ 実施例１のように真空排気した後、第１のクロム被膜約
30Å、酸化クロム被膜約250Å形成し、更に第２のクロ
ム被膜約1500Åの３層構成により形成し、カバーガラス
上面から見ると茶金色となった。Example 2 After evacuation as in Example 1, the first chrome coating approximately
A 30 Å, chrome oxide film of about 250 Å was formed, and then a second chrome film of about 1500 Å was formed with a three-layer structure, and it became a brown gold color when viewed from the top surface of the cover glass.
これは密着強度テストにおいて良好な結果となった。ま
た色調のバラツキが少ないものであった。This gave good results in the adhesion strength test. Further, there was little variation in color tone.
実施例３ 実施例１のように真空排気した後、第１のクロム被膜約
64Å、酸化クロム約300Å、更に第２のクロム被膜約150
0Åを順次構成し、３層構成にするとカバーガラス上面
から見た場合黒色となった。Example 3 After evacuation as in Example 1, the first chrome coating approximately
64Å, chrome oxide about 300Å, and second chrome coating about 150
When 0Å was sequentially formed and a three-layer structure was formed, it became black when viewed from the upper surface of the cover glass.
これは密着強度テストにおいて良好な結果となった。ま
た色調のバラツキが少ないものであった。This gave good results in the adhesion strength test. Further, there was little variation in color tone.
以上、各実施例において、クロムおよび酸化クロム被膜
を真空蒸着で形成したが、スパッタリング、イオンプレ
ーティング等の物理蒸着法により形成してもよい。As described above, in each of the examples, the chromium and chromium oxide coatings are formed by vacuum vapor deposition, but they may be formed by physical vapor deposition such as sputtering and ion plating.
また色調については黒色、茶金色蒸着膜についてのみ記
載したが、各層の膜厚を変えることによりグレー、紫
色、紺色の蒸着膜も可能である。Regarding the color tone, only the black and brown gold vapor deposition films are described, but gray, purple, and navy blue vapor deposition films are also possible by changing the film thickness of each layer.
本発明によれば、次のような効果を上げることが出来

（１）従来の硫化亜鉛に比べると干渉色の変化が少ない
ため、蒸着部においてバラツキの少ない、所望の色調を
得ることができ、カバーガラスの上面から見ると時計の
文字板などの周辺に装飾的な色の効果が見られる。(1) Compared with the conventional zinc sulfide, there is less change in interference color, so it is possible to obtain the desired color tone with less variation in the vapor deposition part, and when viewed from the top of the cover glass, decoration around the dial of the watch etc. You can see the effect of color.
（２）クロムおよび酸化クロムのクロム系のみの組合わ
せによる膜構成のため、密着強度が高く膜が剥離しにく
