Description
【０００１】
【発明の属する技術分野】
この発明は、たとえば装飾品・装身具・文房具・家庭用品・玩具などの製品の表面に、イオンプレーティングやスパッタリング技術を用い、装飾や表示あるいは趣味感を高める目的で多色の模様を形成する製品表面への多色模様形成法に関する。
【０００２】
【従来の技術】
従来、この種の多色模様形成法としては、たとえば特開昭６３−１２８１６６号公報、特開昭６４−７５６６０号公報、特開平２ー２８２４６７号公報に示されるように、まずはじめに有色被覆を施し、次いで残したい部分をマスキングしてから、溶剤に漬けて有色被覆の一部を取り除き、その後マスキング剤を除去したり、はじめにマスキングしてから、有色被覆を施し、その後マスキング剤を除去したりし、装飾品等の製品の表面に多色模様を形成していた。
【０００３】
【発明が解決しようとする課題】
ところが、このような従来の多色模様形成法では、
▲１▼ 手作業やスクリーン印刷・パッド印刷等の印刷でマスキングを行うが、マスキング剤の塗布技術の限界から、細かい模様を描くことが非常に困難であった。▲２▼ １色ごとにマスキングしなければならないから、面倒でコスト高となった。
【０００４】
そこで、この発明の目的は、装飾品等の製品の表面に、コスト高となることなく、細かい多色模様を施すことができるようにすることにある。
【０００５】
【課題を解決するための手段】
そのため、請求項１に記載の製品表面への多色模様形成法は、製品の表面に反射面を形成し、その反射面上にイオンプレーティングまたはスパッタリングにより第１透明膜をつくり、その第１透明膜にレーザーマーキングで書込みを行うことによりその書込みを行った部分の前記第１透明膜を除去して模様および文字の少なくとも一方を描き、その後前記書込みを行って前記第１透明膜を除去した部分は前記第１透明膜を介さずに前記反射面上に、その他の第１透明膜があるところはその第１透明膜を介して前記反射面上に再度イオンプレーティングまたはスパッタリングにより第２透明膜を形成してなる、ことを特徴とする。
【０００７】
【発明の実施の形態】
以下、図面を参照しつつ、この発明の実施の形態につき説明する。
請求項１に記載の製品表面への多色模様形成法では、たとえば図１に示すように、まずはじめにプラスチック製品１０の表面に反射面１０ａを形成する。
【０００８】
次いで、図２に示すように、その反射面１０ａ上にイオンプレーティングによりＴｉＯ2の第１透明膜１１を膜厚ｂ1でつくる。
【０００９】
それから、その第１透明膜１１にレーザーマーキングで書込みを行うことにより、図３（Ａ）に示すようにその書込みを行った部分イの第１透明膜１１を除去して同図（Ｂ）に示すように「Ａ」の文字を描く。
【００１０】
その後、第１透明膜１１があるところはその第１透明膜１１を介して反射面１０ａ上に再度イオンプレーティングで、図４（Ａ）および（Ｂ）に示すように同様にＴｉＯ2の第２透明膜１２を今度は膜厚ｂ2で形成する。
【００１１】
これにより、書込みを行った部分イは第２透明膜１２の膜厚ｂ2だけで成膜し、その他の部分は第１透明膜１１の膜厚ｂ1にその第２透明膜１２の膜厚ｂ2を加えた厚さｂ3で成膜する。
【００１２】
この結果、膜厚ｂ2と膜厚ｂ3の相違により反射面１０ａの反射で、書込みを行った「Ａ」という文字の部分イとその他の部分とで干渉色が相違することとなり、異なる地の色から「Ａ」という文字が浮き上がって見えることとなる。
【００１３】
書込みを行った部分イおよびその他の部分の色は、膜厚ｂ1・ｂ2を変えることにより適宜変更することができる。
【００１４】
図５ないし７には、請求項１に記載の発明の実施の他の形態を示す。図示多色模様形成法では、まずはじめにステンレス製品２０の反射面２０ａ上にスパッタリングによりＳｉＣの第１透明膜２１を膜厚ｂ4でつくる。
【００１５】
それから、その第１透明膜２１にレーザーマーキングで書込みを行うことにより、図６（Ａ）に示すようにその書込みを行った部分ロの第１透明膜２１を除去して同図（Ｂ）に示すように「ハートマーク」の模様を描く。
【００１６】
その後、第１透明膜２１があるところはその第１透明膜２１を介して反射面２０ａ上に再度スパッタリングで、図７（Ａ）および（Ｂ）に示すように同様にＳｉＣの第２透明膜２２を今度は膜厚ｂ5で形成する。
【００１７】
これにより、書込みを行った部分ロは第２透明膜２２の膜厚ｂ5だけで成膜し、その他の部分は第１透明膜２１の膜厚ｂ4にその第２透明膜２２の膜厚ｂ5を加えた厚さｂ6で成膜する。
【００１８】
この結果、膜厚ｂ5と膜厚ｂ6の相違により反射面２０ａの反射で異なる干渉色を呈し、たとえば書込みを行った「ハートマーク」の模様の部分ロはピンクとなり、その他の部分はグリーンとなって、グリーンの地の色からピンクの「ハートマーク」の模様が浮き出して見えることとなる。
【００１９】
この場合ももちろん、書込みを行った部分ロおよびその他の部分の色は、膜厚ｂ4・ｂ5を変えることにより適宜変更することができる。
【００２１】
【発明の効果】
したがって、請求項１および２に記載の発明によれば、レーザーマーキングで書込みを行うから、従来のマスキング剤の塗布に比べはるかに精密に描くことができ、装飾品等の製品の表面に、コスト高となることなく、細かい多色模様を施すことができる。

BACKGROUND OF THE INVENTION
The present invention uses, for example, ion plating or sputtering technology on the surface of products such as ornaments, jewelry, stationery, household items, and toys to form a multicolor pattern for the purpose of decoration, display, or hobby. The present invention relates to a method for forming a multicolor pattern on a surface.
[0002]
[Prior art]
Conventionally, as this type of multicolor pattern forming method, for example, as shown in JP-A-63-128166, JP-A-64-75660, and JP-A-2-282467, first, a colored coating is applied. Apply, then mask the part you want to leave, soak in a solvent to remove a portion of the colored coating, then remove the masking agent, mask it first, then apply the colored coating, and then remove the masking agent However, a multicolor pattern was formed on the surface of a product such as a decorative product.
[0003]
[Problems to be solved by the invention]
However, in such a conventional multicolor pattern forming method,
(1) Masking is performed by manual work or printing such as screen printing or pad printing. However, it is very difficult to draw a fine pattern due to the limitation of the coating technique of the masking agent. (2) Since each color must be masked, it is cumbersome and expensive.
[0004]
SUMMARY OF THE INVENTION An object of the present invention is to make it possible to give a fine multicolor pattern on the surface of a product such as a decorative product without increasing the cost.
[0005]
[Means for Solving the Problems]
Therefore, in the method for forming a multicolor pattern on the product surface according to claim 1, a reflective surface is formed on the product surface, and a first transparent film is formed on the reflective surface by ion plating or sputtering. Writing the transparent film with laser marking removes the first transparent film of the written portion to draw at least one of a pattern and characters, and then performs the writing to remove the first transparent film The portion is not on the first transparent film on the reflecting surface, and the other first transparent film is on the reflecting surface via the first transparent film, and is again second plated by ion plating or sputtering. It is characterized by forming a film .
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
In the method for forming a multicolor pattern on the product surface according to the first aspect, for example, as shown in FIG. 1, first, the reflecting surface 10 a is formed on the surface of the
[0008]
Next, as shown in FIG. 2, a first transparent film 11 of TiO 2 with a film thickness b 1 is formed on the reflecting surface 10a by ion plating.
[0009]
Then, by writing to the first transparent film 11 with laser marking, the first transparent film 11 of the part A where the writing was performed is removed as shown in FIG. Draw the letter “A” as shown.
[0010]
Thereafter, the place where the first transparent film 11 is present is again ion-plated on the reflecting surface 10a via the first transparent film 11, and the second TiO 2 film is similarly formed as shown in FIGS. 4 (A) and 4 (B). 2
[0011]
As a result, the written portion i is formed only with the film thickness b 2 of the second
[0012]
As a result, due to the difference between the film thickness b 2 and the film thickness b 3 , the interference color is different between the part “A” written by the reflection surface 10 a and the other part due to the reflection on the reflecting surface 10 a, and different grounds. The letter “A” will appear to rise from the color of.
[0013]
The colors of the portion A and other portions where the writing has been performed can be appropriately changed by changing the film thicknesses b 1 and b 2 .
[0014]
5 through 7 show another embodiment of the first aspect of the present invention. In the illustrated multicolor pattern forming method, first, a first
[0015]
Then, by writing to the first
[0016]
Thereafter, where the first
[0017]
As a result, the part B in which writing has been performed is formed only with the film thickness b 5 of the second
[0018]
As a result, due to the difference between the film thickness b 5 and the film thickness b 6 , the interference surface exhibits different interference colors due to the reflection of the reflection surface 20a. For example, the written portion of the “heart mark” pattern becomes pink and the other portions are green. As a result, a pink “heart mark” pattern appears from the color of the green ground.
[0019]
In this case, as a matter of course, the colors of the portion B and other portions where writing has been performed can be appropriately changed by changing the film thicknesses b 4 and b 5 .
[0021]
【The invention's effect】
Therefore, according to the first and second aspects of the invention, since writing is performed by laser marking, it is possible to draw much more accurately than the application of a conventional masking agent, and the cost on the surface of a product such as a decorative product is reduced. A fine multicolor pattern can be applied without becoming high.
