本発明は、腕時計用カバーガラス特にサファイヤガラス
の着色方法に関−するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for coloring a cover glass for a wristwatch, particularly sapphire glass.
従来から着色したカバーガラスは使われている。 Colored cover glasses have traditionally been used.
−また、ガラスの表面に印刷、蒸着等を施すことにより
、ガラスの一部に着色することができる。しカシ、表面
着色でなくガラス素材を着色する方法でガラスの一部に
着色することは困難であった。-Also, a part of the glass can be colored by printing, vapor deposition, etc. on the surface of the glass. However, it was difficult to color a part of the glass by coloring the glass material instead of coloring the surface.
本発明はカバーガラス材質としてサファイヤガラスを使
い、その素材の一部に着色を施こそうとするものである
。The present invention uses sapphire glass as a cover glass material and attempts to color a part of the material.
サファイヤガラスは紫外線を照射すると茶色に着色する
という性質がある。Sapphire glass has the property of turning brown when exposed to ultraviolet light.
これはサファイヤガラス中に含まれる酸化チタンが紫外
線の作用により変質するためである。本発明はこの性質
を利用し、サファイヤガラスの一部をしやへいした状態
で紫外線を照射し、一部が着色するようにしたものであ
る。This is because the titanium oxide contained in sapphire glass is altered by the action of ultraviolet light. The present invention takes advantage of this property and irradiates ultraviolet rays while a part of the sapphire glass is softened, so that part of the sapphire glass becomes colored.
以下、実施例に基づいて本発明を説明する。第１図は本

穴から紫外線が当たった部分５は茶色に着色した。Hereinafter, the present invention will be explained based on Examples. FIG. 1 is a schematic diagram showing an embodiment of the present invention. Ultraviolet rays are irradiated from the ultraviolet ray irradiation device 3. A sapphire glass 1 is placed at a distance of 20 degrees from the ultraviolet irradiation device 3, and a barrier plate 2 with a hole partially formed on top of the sapphire glass 1? put. In this state, ultraviolet rays were irradiated for 1 minute. As a result of this process, the portion 4 of the sapphire glass covered with the shielding plate 2 remained unchanged, and the portion 5, which was exposed to ultraviolet rays through the hole in the shielding plate, was colored brown.

この着色サファイヤガラスは紫外線照射条件を管理する
ことにより多数のサファイヤガラスを同じ仕上がりにす

とにより種々のパターンの着色模様を得ることができる
。(Fig. 2) This colored sapphire glass can be made to have the same finish on many pieces of sapphire glass by controlling the ultraviolet irradiation conditions. Also, since the glass itself is colored,
It does not peel off. Various colored patterns can be obtained by changing the pattern of the sheet.
以上実施例に述べたように本発明によれば、簡単に一部
に着色したサファイヤガラスを得ることができる。As described in the embodiments above, according to the present invention, partially colored sapphire glass can be easily obtained.
