以下、本考案の光沢を有する金箔等について図面を参照して詳細に説明する。  Hereinafter, the glossy gold foil of the present invention will be described in detail with reference to the drawings.

図1は本考案の光沢を有する金箔等の説明用斜視図であり、図2は真空蒸着装置の説明図である。  FIG. 1 is an explanatory perspective view of a glossy gold foil or the like according to the present invention, and FIG. 2 is an explanatory view of a vacuum evaporation apparatus.

図1で示すように本考案の光沢を有する金箔等は、薄い板状又はフィルム状の乾燥した概ね透明のゼラチン層1の一面に、金又は銀の薄膜層2をコーティングすることにより得ることができる。  As shown in FIG. 1, the glossy gold foil or the like of the present invention can be obtained by coating a thin plate-like or film-like dry generally transparent gelatin layer 1 with a thin film layer 2 of gold or silver. it can.

ゼラチンとは、動物の皮膚や骨、腱などの結合組織の主成分であるコラーゲンに熱を加えて抽出したもので、タンパク質を主成分としており、主に食品や医薬品などに使われており、精製度の低いものを膠(にかわ)と称して日本画の画材および工芸品などの接着剤として利用されている。  Gelatin is extracted by applying heat to collagen, which is the main component of connective tissues such as animal skin, bones, and tendons, and it is mainly used for food and pharmaceuticals. What has a low degree of purification is called glue, and is used as an adhesive for Japanese painting materials and crafts.

さらに薄い板状又はフィルム状のゼラチン層1は柔軟性に富み、切断等の加工性は良好である。  Further, the thin plate-like or film-like gelatin layer 1 is rich in flexibility and has good workability such as cutting.

さらに薄い板状又はフィルム状のゼラチン層1は透明で平滑性が良好であるため、ゼラチン層1の一面に金や銀の薄膜層2を形成すれば、非常に平滑性が良好で光沢のある金や銀の薄膜層2が得られると共に、ゼラチン層1のもう片面側から観察しても金色又は銀色の美しい色が観察できるので、ゼラチン層1の両面より美しい色合いを観察できるのである。  Further, since the thin plate-like or film-like gelatin layer 1 is transparent and has good smoothness, if a thin film layer 2 of gold or silver is formed on one surface of the gelatin layer 1, the smoothness is very good and glossy. A gold or silver thin film layer 2 is obtained, and a beautiful color of gold or silver can be observed even when observed from the other side of the gelatin layer 1, so that a beautiful hue can be observed from both sides of the gelatin layer 1.

さらにゼラチン層1は水溶性であるので、金又は銀の薄膜層2をコーティングした金箔や銀箔を水で濡らせばゼラチン層1が接着剤として作用するので、いろいろな固形食品の上に金箔や銀箔を貼ることが可能であり、金箔や銀箔は人体に悪影響を及ぼすことがないばかりか、銀箔は抗菌性を有するので体内において良い影響を及ぼすことも期待できるのである。  Furthermore, since the gelatin layer 1 is water-soluble, the gelatin layer 1 acts as an adhesive when the gold foil or silver foil coated with the gold or silver thin film layer 2 is wetted with water. The gold foil and silver foil do not have an adverse effect on the human body, and since the silver foil has antibacterial properties, it can be expected to have a positive effect in the body.

さらに接着剤として作用するゼラチン層1を利用して金箔や銀箔を和紙による面や木彫りの人形といった工芸品にも貼り付けることができ、良好な加工性を有するので自由な形状の金箔や銀箔による美しい工芸品等を提供できるといった効果も有するのである。  Furthermore, using gelatin layer 1 that acts as an adhesive, gold and silver foil can be affixed to crafts such as Japanese paper surfaces and wooden carved dolls. It also has the effect of providing beautiful crafts.

図2で示すように、金又は銀の薄膜層2は真空蒸着の手法によりコーティングすることが可能であり、その方法を説明する。  As shown in FIG. 2, the gold or silver thin film layer 2 can be coated by a vacuum deposition method, and the method will be described.

図2は抵抗加熱式による真空蒸着装置であり、その構造は、真空容器5内の下部に原料を加熱するヒーターを兼ねたタングステン製等のボート6が固定され、真空容器5内の上部には金や銀の薄膜層2が蒸着される試料7としての板状又はフィルム状のゼラチン層1による資料7が固定されている。  FIG. 2 shows a resistance heating type vacuum vapor deposition apparatus. The structure is such that a boat 6 made of tungsten, which also serves as a heater for heating the raw material, is fixed to the lower part of the vacuum container 5. A material 7 by a plate-like or film-like gelatin layer 1 as a sample 7 on which a gold or silver thin film layer 2 is deposited is fixed.

この抵抗加熱式による真空蒸着装置で金や銀の金属薄膜層2を形成するには、所定の割合に計量された薄膜層用の金や銀の金属8を真空容器5内のヒーターを兼ねたボート6に収め、真空容器5内を所定の真空度となるようポンプ9にて排気した後、ボート6に所定の電流を流してヒーターを兼ねたボート6の温度を徐々に上げれば、金や銀の金属8の融点温度以上に達した時点で金属は溶解して気化し、試料7の内側に付着して蒸着されるのである。  In order to form the gold or silver metal thin film layer 2 by this resistance heating type vacuum vapor deposition apparatus, the gold or silver metal 8 for the thin film layer weighed at a predetermined ratio was also used as a heater in the vacuum vessel 5. After being housed in the boat 6 and evacuated by the pump 9 so that the inside of the vacuum vessel 5 has a predetermined degree of vacuum, a predetermined current is passed through the boat 6 to gradually raise the temperature of the boat 6 that also serves as a heater. When the temperature reaches the melting point temperature of the silver metal 8 or higher, the metal dissolves and vaporizes and adheres to the inside of the sample 7 and is deposited.

蒸着作業が終了したら真空容器5内に空気を導入し、真空容器5内から金や銀の金属薄膜層2が形成された資料7を取り出すことにより、光沢を有する金箔や銀箔を得ることができるのである。  When the vapor deposition operation is completed, air is introduced into the vacuum vessel 5 and the material 7 on which the gold or silver metal thin film layer 2 is formed is taken out of the vacuum vessel 5 to obtain a shiny gold foil or silver foil. It is.
