［発 明 の 目 的］
（産業上の利用分野）
この発明は、チタン、チタン合金、チタンコーティング
材の如きチタン材に、耐久性に優れ、且つ高価で美しい

法に関する。[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention provides a highly durable, expensive, and beautiful coloring method for titanium materials such as titanium, titanium alloys, and titanium coating materials. , relates to a method for coloring titanium materials that is easy and inexpensive.
（従来の技術）
従来から、イヤリングやカフス釦等の装身具は、金属に
て形成されているものが大部分であり、その金属も、銅
或いは銅合金等が大部分を占めている。(Prior Art) Traditionally, most accessories such as earrings and cufflinks have been made of metal, and most of these metals have been made of copper or copper alloys.
又、軽量なものとして、チタン金属を成形した装身具等
が市場に出回っており非常に好評である。Furthermore, lightweight accessories made of titanium metal are available on the market and are very popular.
このチタン金属の彩色は、塗料を塗布して行なったり、
或いは、表面に陽極酸化被膜を形成して行ったりしてい
た。The coloring of this titanium metal is done by applying paint,
Alternatively, an anodic oxide film was formed on the surface.

代用品としてプラスチックを用いられることもあるが、
どうしても貧弱なイメージを拭い去ることができず、装
身具としてはどうしても敬遠されることが多かった。(Problems to be solved by the invention) <Problems with the prior art> However, in the case of metals such as the above-mentioned metals or copper alloys, heavy loading may be a problem, and in reality, it is difficult to Book the thickness
Attempts have been made to solve the problem of weight by reducing the weight of the machine by making it smaller, or by making it smaller overall. However, in order to make the wall thinner, the processing technology is difficult, which leads to an increase in cost, and if the wall thickness is made smaller, the fashionability is naturally limited. Also, plastic is sometimes used as a substitute to reduce weight.
Unable to shake off its poor image, it was often avoided as an accessory.
そこで、前述したチタン金属を用いて装身具を形成する
と軽量且つ高価な雰囲気を醸し出す装身具が得られるの
であるが、実際にはその加飾において大きな問題点があ
った。Therefore, if the above-mentioned titanium metal is used to form an accessory, it is possible to obtain an accessory that is lightweight and gives off an expensive atmosphere, but in reality, there are major problems in its decoration.
その一つは、チタン金属の表面に、めっきや塗料のみに
よって全面を加飾するとなると、あまり高級感がなく、
せっかくチタン金風を用いてもこの金３の特長である高
価なイメージを全く生かすことができない問題点があっ
た。One of them is that if the entire surface of titanium metal is decorated with only plating or paint, it will not look very luxurious.
Even if titanium gold was used, there was a problem in that the expensive image, which is a feature of gold 3, could not be fully utilized.
もう一つは、チタン金属の高価なイメージを生かすため
、その表面に陽極酸化被膜を形成し、チタン独特の彩色
を施して加飾すれば優れた装身具が得られるのであるが
、この陽極酸化被膜は、空気中に単に放置しておく分に
は何等問題はないのである。ところが、この被膜は極端
に薄いから、擦れる部分等に装着すると、摩滅してしま
うことが多くなるという問題点が発生する。そのため、
その陽極酸化被膜の上に透明なラッカー等により保護膜
を形成しようとしたが、この酸化被膜には微小孔が多数
存在し、その微小孔にラッカーが詰って変色してしまい
、本来の高価な雰囲気を醸し出す色が褪せてしまうとい
う問題点が発生してしまった。Another reason is that in order to take advantage of the expensive image of titanium metal, an anodized film is formed on its surface, and if it is decorated with titanium's unique coloring, excellent jewelry can be obtained. There is no problem in simply leaving it in the air. However, since this coating is extremely thin, there is a problem in that it is often worn away when it is attached to areas that get rubbed. Therefore,
Attempts were made to form a protective film using transparent lacquer on the anodic oxide film, but this oxide film had many micropores, and the lacquer clogged the micropores and caused discoloration, making the original expensive A problem arose in that the colors that created the atmosphere faded.
