本発明は、アルミニウム等の電気化学的方法で
着色可能な金属材の表面に任意の模様の着色皮膜
を形成する方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for forming a colored film in an arbitrary pattern on the surface of a metal material such as aluminum that can be colored by an electrochemical method.

それぞれ示している。 The present inventors have already reported in Japanese Patent Application Laid-Open No. 57-104690 that an electrolytic solution is
A transfer target 3 made of a metal material that can be colored by an electrochemical method and a plate electrode 4 having a non-uniform electric resistance distribution in a desired pattern are placed close to each other and subjected to electrolytic treatment. An electrical pattern coloring method for metal is proposed in which a pattern corresponding to the current distribution flowing between the transfer body 3 is formed on the surface of the transfer body 3. In FIG. 1, reference numeral 1 indicates an electrolytic cell, 5 an insulator such as silk cloth, 6 a weight, and 7 a power source.
ところが、このような方法において、版電極４
として模様状の不均一な電気抵抗分布を現出せし
めるために、プリント基板上に模様状電極４ａを
形成したものを採用する場合には、第２図のグラ
フに示すように、模様状電極４ａの給電部８から

が低下するという問題が生じる。この鮮明度ｙの
低下は指数関数的なものであり、距離ｘ＝20cm以
上（但し、模様状電極４ａの巾が約１mmの場合）
ではほぼ一定となる。 However, in such a method, the plate electrode 4
When adopting a patterned electrode 4a formed on a printed circuit board in order to create a patterned non-uniform electrical resistance distribution, as shown in the graph of FIG. As the distance x from the power supply unit 8 increases, the clarity y of the transferred pattern increases.
A problem arises in that the value decreases. This decrease in visibility y is exponential, and the distance x = 20 cm or more (provided that the width of the patterned electrode 4a is approximately 1 mm)
It becomes almost constant.
この鮮明度ｙの低下の原因を解明するために模
様状電極４ａの電気回路を第３図図示のようなも
のと考えてみる。ここにｒは模様状電極４ａの各
部分の抵抗、Ｒは模様状電極４ａと被転写体３と
の間の抵抗をそれぞれ示す。 In order to elucidate the cause of this decrease in sharpness y, let us consider the electric circuit of the patterned electrode 4a as shown in FIG. Here, r represents the resistance of each part of the patterned electrode 4a, and R represents the resistance between the patterned electrode 4a and the transfer target 3.
しかして、被転写体３への転写電流ｉを求める
ために各点の電圧Ｖを計算すると、
V3＝i3R3
V2＝V3＋i3r3＝i2R2
V1＝V2＋（i2＋i3）r2＝i1R1
現われる量はすべて正の値であるところから、
V1＞V2＞V3となる。 Therefore, when calculating the voltage V at each point to obtain the transfer current i to the transfer target 3, V 3 = i 3 R 3 V 2 = V 3 + i 3 r 3 = i 2 R 2 V 1 = V 2 + (i 2 + i 3 ) r 2 = i 1 R 1Since all the quantities that appear are positive values, V 1 > V 2 > V 3 .
即ち、第４図のグラフに示すように、模様状電
極４ａの給電部８からの距離ｘが大きくなるに従
つて電圧Ｖが降下することに起因して鮮明度ｙの
低下が生ずると結論できる。実際の回路では点の
数は無限であるが、全く同様な結論となる。 That is, as shown in the graph of FIG. 4, it can be concluded that as the distance x of the patterned electrode 4a from the power supply section 8 increases, the voltage V decreases, resulting in a decrease in the visibility y. . In an actual circuit, the number of points is infinite, but the conclusion is exactly the same.
本発明は、上記の結論に鑑み、模様状電極にお
ける電圧降下を補償し得る構造の版電極を使用し
て、全体的に鮮明な転写模様を得るようにするこ
とを目的とするものである。 In view of the above conclusion, it is an object of the present invention to obtain an overall clear transferred pattern by using a plate electrode having a structure that can compensate for the voltage drop in the patterned electrode.

A plate electrode formed by providing a plurality of voltage drop compensation power supply parts at intervals is placed in close opposition to each other, and current is applied between the two to form a transfer pattern corresponding to the patterned electrode on the surface of the transfer target. It is a feature.
