Abstract

PURPOSE:To restrain a picture from cracking or separating, and maintain the vividness at the picture manufacturing period, and besides improve the picture printing, furthermore enable a stable quality to be maintained through raising the close adherence by using a copper foil being formed with a surface coating layer as a base material. CONSTITUTION:A copper foil is manufactured successively in such a manner that a metallic material is made an metal electrolytic solution, and the metal is deposited on a rotating cathodic drum, and further, it is separated therefrom then. In the next place, the metallic foil 1 forms various kinds of one layered or multi-layered surface coating layer at a stage or multi-stages. For example, at the first stage 4, the fine particles of copper and / or copper oxide are given to the metallic foil in order to increase the adhering strength among the metallic foil and colors and / or rear material. And, at the second stage 5, a coating layer of brass or zinc is formed so as to give a long period corrosive prevention. And, at the third stage 6, an anticorrosive treatment is further given for preventing oxidation of the metallic foil or peripheral oxidation during the cutting period. Through forming the surface coating layer mentioned above, the close adherence of the colors is raised considerably, thereby making it a picture base material with an excellent anticorrosive property.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The invention of this application relates to a support for paintings using metal foil as a base material, which is used when painting oil paintings, Japanese paintings, etc.

[Prior art and the problem to be solved by the invention] When painting an oil painting, a linen canvas is usually stretched over a wooden frame.
is used. Some canvases are made of cotton, and there are no restrictions on painting on boards or stones, so you can often see paintings painted on plywood and exhibited at exhibitions.

However, in most cases, cloth canvas is used. This is thought to be due to the fact that cloth has a texture, which makes it easy for paint to adhere to it, making it easier to place the paint when writing comparisons.

Oil painting was introduced from the West during the Meiji period, and to put it simply, it can be said to be a method of hardening paint with resin.

As a dual-use liquid, just as watercolors dissolve with water and Japanese paintings dissolve with glue, oil plays an extremely important role in oil paintings.

This oil can be roughly divided into three types: melting oil, which dissolves oil paint according to each technique, oil, which gives the painting its original luster, and oil, which preserves the painting with care.

Usually, commercially available oil paints themselves have already been refined to be easy to use.

A brief introduction to oil paintings is as above, but on the other hand, Japanese paintings have traditionally been made by impregnating paper with pigments and often preserving them as scrolls. For this reason, it was not possible to apply paint so thick that it could not be rolled.

However, as the above-mentioned oil paintings became more popular, Japanese paintings also started to be framed, and the tendency was to use thicker paint. In other words, people began applying a layer of ``glue'' on top of the paper to prevent the paint from seeping in, and then layering the paint thickly on top of it. For this reason, in parallel with the unique Japanese painting method, oil painting style Japanese paintings also emerged.

In this way, various techniques starting from oil painting and Japanese painting were developed, and many excellent paintings were created.
There is a very big problem with the created painting.

This is the result of cracks in the painting, and in some cases there is even a risk of it falling off. Particularly in Japan, which is extremely dry and humid, climate change has made them more brittle and more susceptible to damage.

Even in Western Europe, where the climate is dry and stable, when you look closely at famous paintings from the past, you can see countless cracks. Many people cannot help but feel sorry for the fact that dust accumulates in the cracks, making it impossible to maintain the vivid quality of the painting at the time of production, and that the painting will not only deteriorate over the years, but also be lost due to flaking. I think that the.

Cracks in paintings like this can be caused by the paint or base coating, but they are often caused by changes in the dryness and humidity of the base material, such as canvas, or expansion and contraction due to temperature changes.

Cracks in paintings such as those described above can be seen not only in paintings that are painted thickly, but also in Japanese paintings that tend to resemble oil paintings.

Despite these problems, the reality is that research is even being carried out to restore high-quality paintings in order to preserve them. Also, in old paintings, metal plates (
Plates of copper, iron, zinc, silver, and lead), particularly corrosion-resistant copper plates, have been used as base materials.

This is mainly because after the Reformation, when Cadric's side sent out missionaries in search of missionary sites in the New World, they carried with them an oil painting of the image on a copper plate.

This is thought to be because it is lighter than a board, has less bulk, is far less susceptible to peeling or cracking than cloth, and is also resistant to some rain and heat.

However, since copper itself was expensive, it was impossible to obtain a flat surface, paint did not adhere well to it, and it could only be produced using very special techniques, so copper has hardly been seen since the 18th century and is still used today. It has been reached.

[Means to solve the problem]

In order to solve the above problems of the support for paintings, copper or copper alloy,
At least one layer of indium or indium alloy, zinc or zinc alloy, chromium or chromium alloy, nickel or nickel alloy, iron or iron alloy, cobalt or cobalt alloy, or an oxide of the above metal or a composite of the above metal and the oxide. A support for paintings using metal foil as a base material, characterized in that it is provided with a surface coating layer containing a metal foil, and a support for paintings, characterized in that the surface coating layer is applied on both sides of the metal foil. , and a support for oil paintings, which is a support for Japanese paintings, and a support for paintings, which is a support for Japanese paintings, and that the support for paintings is a canvas. The above-mentioned support for a picture, characterized in that the support for a picture is a support for a mural painting, and the base material is a metal foil in which the surface coating layer is further subjected to anti-corrosion treatment. The above-mentioned support for a picture is characterized in that it is composed of the base material of the metal foil and the backing material of a polypropylene nonwoven fabric, and the base material of the metal foil. The above-mentioned support for a picture, characterized in that it is made of a backing material of plaster, and the support for a picture, characterized in that the outermost surface is provided with a protective resin sheet that can be peeled off at the time of use. and the support for a picture, which is characterized by being an embossed metal foil, and the support for a picture, which is characterized by using an electrolytic metal foil as a base material of the metal foil. .

This prevents the painting from cracking or peeling,
It not only maintains the vividness of the painting at the time it was made, but also improves the adhesion and adhesion of the paint, making it possible to maintain stable quality.

[Detailed description of the invention]

The use of gold gtN plays a major role in preventing cracking and peeling due to dryness, humidity, and temperature changes.
It is extremely important to improve the adhesion and adhesion of paint, which are major drawbacks when using metal base materials, and this was achieved for the first time with the metal foil of the invention of this application. be.

The metal foil has a thickness of 1 μm to 3 mm, preferably 10 μm.
= 0,5 mm) electrolytic foil or rolled foil is used.

As shown in the conceptual diagram of the foil manufacturing process in Figure 1a, electrolytic foil is generally manufactured by using a metal raw material as a gold a''m solution, depositing the metal on a rotating cathode drum, and then peeling it off to continuously deposit gold. ytW3 is produced.The metal foil thus obtained is generally called main seedling 3, but the surface in contact with the drum is smooth and is called surface 8 (shining surface), and the surface on the opposite side is smooth. As shown in FIG. 2, a surface having a large number of electrically deposited irregularities is called an M surface (matte surface).

Next, this metal foil (main seedling) is coated with various single or multilayer surface coating layers in one or multiple stages (three stages in the figure) as shown in Figure 1. - By way of example, in the first step 4, fine particles of copper and/or copper oxide are applied to the metal foil in order to increase the adhesive strength between the metal foil and the paint and/or backing. Second
In step 5, a brass or zinc coating is applied to provide long-term corrosion resistance. In the third step 6, an anti-rust treatment can be further applied to prevent oxidation of the metal foil or oxidation of the edges during cutting.

Further, after these steps, the painting support such as canvas can be coated with a protective sheet that can be peeled off by hand during use. This protective sheet has the role of preventing contamination by preventing hand oils from getting on the metal foil.

By forming the above-mentioned surface coating layer, it is possible to significantly improve the adhesion of paint and provide a base material for paintings with excellent corrosion resistance.

The metal foil substrate thus obtained has several additional advantages when compared to conventional wood or cloth. It retains the adhesion of paint and at the same time has excellent flatness.
It is smooth, and there is no need to fill in pores or surface undulations with a base coat (of course, a base coat is acceptable, and the present invention includes this). And mainly because copper tones can also be used as a base coat at the same time. If you want to bring out a strong copper color such as red, you can achieve it by applying a copper coating layer (plating layer).
Colors can be matched from white, silver, and even brass to golden yellow. Further, the copper-nickel alloy layer can be varied from black to brown.

Furthermore, a coating layer of chromium or chromium alloy (including chromate and zinc chromate treatment), nickel or nickel alloy, iron or iron alloy, cobalt or gobalt alloy, indium or indium alloy, zinc or zinc alloy, or oxides thereof is formed. By doing so, it is possible to improve corrosion resistance and make the unique color tones of each material uniform. Furthermore, it is also possible to further plate these metals, alloys, or oxides of these metals with other metals such as noble metals.

The present invention includes these.

The metal foil base material described above can also be embossed to increase mechanical adhesive strength.

The metal foil surface coating layer described above is applied to one or both of the front and back surfaces to which paint is applied. Adhesion to the back surface is also important for adhesion of the backing material.

The metal foil base material thus formed is cut to a predetermined size.

In addition to traditional canvas materials such as polypropylene nonwoven fabric, linen, and cotton, backing materials include veneer, wood board, paper, plaster, resin,
Tiles etc. can be used.

This can be selected according to the painter's preference, but the characteristics of using metal foil will not be lost.

Furthermore, since the metal foil base material can be easily cut with a cutter or the like, it can be used as a support for canvas boards, pin-ups, and even murals. Furthermore, since these can be adhered to general buildings, they can be used as interior items such as interior and exterior items, doors, shelves, etc., and also have the feature that they can be easily replaced and stored.

When used as a canvas, it has a suitable amount of strength and elasticity, so you can attach a backing material such as cloth to it, tension it against a wooden frame, and feel the pleasant elasticity that you feel when you apply a paintbrush to the canvas. Can be done.

Although electrolytic foil has been given as an example of metal foil, rolled foil can also be used. Various covering layers may be formed in the same manner as the electrolytic foil. Rolled foil has more flexibility than electrolytic foil and is superior in strength.

The metal foil used as the base material is iron foil or stainless steel foil.

Metal foils such as high nickel iron alloy, aluminum or aluminum alloy foil, titanium foil, lead foil, tin or gold foil can be used. Stainless steel foil, aluminum or aluminum alloy foil, and titanium foil are superior in terms of durability (corrosion resistance, weather resistance), but the same effect can be obtained with other metal foils by applying rust prevention treatment. .

The above-mentioned foils can be obtained from electrolytically treated foils (electrodeposited foils) or rolled foils, but each is difficult to manufacture, so they are appropriately selected depending on the type of metal foil.

Also, when forming a coating layer on the surface, pretreatment for plating is necessary, and plating layers of various metals (including oxides) are formed using conventionally known plating methods.

In particular, iron foil has advantages over other foils in terms of ease of manufacture and ease of forming a surface coating layer.

The painting method is suitable for oil paintings, acrylic paints, Japanese paintings, pastel paintings, ink paintings, etc., but there is nothing wrong with applying it to other painting methods.

All of them have excellent adhesion to paint, greatly reduce the occurrence of cracking and peeling, maintain the vividness of paintings and have excellent storage stability, and also give a strong sense of pleasure to the touch of a paintbrush. .

〔Effect of the invention〕

As mentioned above, by using the metal foil on which the surface coating layer of the present invention is formed as a base material, it is possible to obtain the color feeling unique to metal foil, to have excellent flatness, and to be convenient and pleasant to touch with a paintbrush. Furthermore, the adhesion to paint, which was a major drawback of metals, has been significantly improved, making it extremely excellent as a conventional support for paintings.

Moreover, it has a remarkable property of being able to prevent the occurrence of severe cracks in conventional paintings, especially when used on canvas.
