Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The invention of this application relates to a painting support using copper foil as a base material to be used when drawing oil paintings, Japanese paintings, and the like.

[Problems to be solved by conventional technology and invention]

Usually, when painting oil paintings, hemp canvas (painting cloth) stretched over a wooden frame is used. The canvas material is made of cotton, and there is no restriction that it must not be drawn on boards or stones, so there are many examples of painting on plywood and exhibiting at exhibitions.

However, fabric canvases are often used. It has a texture on the cloth, good paint paste,
This is probably due to the fact that the paint is relatively well placed when written.

Oil paintings were introduced from the West in the Meiji era,
In a nutshell, it can be said that the paint is hardened with a tar.

Oil is very important in oil painting (oil painting), just as water is used for water and water is used for Japanese painting.

This oil can be broadly classified into two types: a melting oil that melts oil paints in accordance with each technique, an oil that gives the original luster to the painting itself, and an oil that preserves the painting carefully.

Usually, commercially available oil paints are already kneaded so as to be easy to use.

The above is a brief introduction to oil painting.
Japanese paintings, on the other hand, have traditionally been impregnated with hemp paper with pigments and are often stored as scrolls. For this reason, the paint could not be so thick that it could not be wound.

However, as the above-mentioned oil painting spreads, Japanese paintings are also included in the forehead, and the tendency to thicken the paint is changing. In other words, "how" on linen paper (Nika)
It has been changed to paint so that the paint does not seep into it, and to thicken the paint on it. This led to the development of oil painting-like Japanese paintings in parallel with Japanese paintings.

As described above, various techniques starting from oil painting and Japanese painting have been developed, and many excellent paintings have been born. However, the created paintings have a very serious problem.

It is a crack in the painting, and in some cases even the risk of spalling. It can be said that especially in Japan where the wet and dry conditions are severe, it becomes brittle due to climate change and is easily damaged.

Even in western Europe, where the climate is dry and stable, countless cracks can be seen when approaching famous past paintings. There are many people who can not forgive the relentless feeling that there is a possibility that the painting will be deteriorated over the years and the painting will be lost due to peeling off, and the painting will not be able to be maintained during the production due to the accumulation of garbage due to cracks I think that the.

Such cracks in paintings may be caused by paintings, ground painting, etc., but they are largely caused by changes in the dryness and humidity of base materials such as campuses and expansion and contraction due to temperature changes.

The cracks in the above-mentioned paintings have been observed not only in thickly painted paintings but also in Japanese paintings that tend to be oil paintings.

Despite these problems, high-quality paintings are even being studied for restoration in order to retain them. In old paintings, a metal plate, particularly a copper plate resistant to corrosion, has been used as a base material.

This was mainly due to the Catholics sending out missionaries after the Reformation in search of a missionary land for the New World, and carrying oil paintings depicting copper statues on copper plates.

This is probably due to the fact that it is lighter than a board, has no bulk, is much less likely to peel or crack than a cloth, and is resistant to some rain and heat.

However, copper itself was expensive, could not obtain a flat surface, painting was poor, and it could be produced only by a very special technique. Has reached.

[Means for solving the problem]

In order to solve the above-mentioned problem of the painting support,
The present inventors have focused on a metal plate and tried to improve it. That is,
It is effective in preventing cracks, has no problem of corrosion due to insects, environment, etc., and does not need to be primed. In addition, we focused on metal plates because of their advantages in that the shape can be freely plastically processed and the strength is strong. The only drawback is to improve the adhesion of paint and the poor glue. That is, the surface of the base material made of copper or copper alloy is provided with mechanical irregularities obtained by one or more mechanical processes of buffing, shot blasting, embossing, lap rolling, dulling, and The uneven surface forms a crushed rolled surface, and the rolled surface further includes copper or copper alloy, tin or tin alloy, indium or indium alloy, zinc or zinc alloy, chromium or chromium alloy, nickel or nickel alloy, iron Or covered with a surface coating layer made of at least one selected from an iron alloy, cobalt or a cobalt alloy, and an oxide of each of the above metals, or a composite of each of the above metals and the above oxide. The back of the base material is hemp, cotton,
An object of the present invention is to provide a painting support characterized by being provided with a backing of any one type of veneer, wood board, paper, plaster, resin and tile.

This suppresses the cracking and peeling of the painting, maintains the sharpness at the time of the painting production, improves the paste of the paint, improves the adhesiveness, and can maintain stable quality.

[Specific description of the invention]

The use of a metal base material plays a major role in preventing cracking and spalling due to dryness and humidity and temperature changes, but it improves the adhesion of paint, which is a major drawback in this case, and improves the glue. This is extremely important and has been achieved for the first time in the metal of the invention of this application.

That is, by providing mechanical unevenness on the surface of the metal base material, the paste and adhesion of the paint are significantly improved, and in particular, polishing with a buff or the like, shot blasting, embossing, rolling with a dull roll, stacking A rolled surface by rolling is very effective because it has mass productivity. The rolled surface obtained by further rolling and crushing the surface provided with mechanical irregularities has a surface as shown in FIG. 1 (b), so that the adhesion is further improved. Further, by applying various coating layers to the surface having mechanical irregularities, the electrodeposited particles of the coating layer are concentrated on the convex portions, and the irregularities are further emphasized and the adhesion of the paint is improved.

Any kind of metal can be applied. In particular, copper and copper alloys have a bactericidal action against microorganisms and the like, and can be said to be extremely excellent materials from the viewpoint of storage.

Further, after these steps, a protective sheet that can be peeled off by hand can be coated when using a painting support such as a canvas. This protective sheet has a role of preventing contamination such as grease of hands from sticking to metal.

The metal base obtained in this way has several further advantages when compared to conventional wood and cloth. It has excellent adhesion and flatness at the same time, it is smooth, and it is not necessary to fill pores and undulations with a ground coat (of course, it is impossible to do a ground coat, The present invention includes this.) This is because the color tone of the metal and the color tone of the coating material can be simultaneously used as an undercoat. Depending on the choice of metal material, it can be varied from red, white, silver, and even brass to golden, black and brown.

Furthermore, it has strength and has the advantage that it can be processed into free shapes because it can be plastically processed.

As the backing material, veneer, wood board, paper, plaster, resin, tile, etc. can be used in addition to conventional canvas materials such as hemp and cotton. Moreover, it can also be used without using a backing material.

This can be selected according to the painter's preference, but the metal features are not lost.

In addition, by using a thin plate that can be easily cut with a cutter or the like as a metal base material, it can be used as a canvas board, a pinup, or a mural support. In addition, since they can be bonded to general buildings, they can be used as interior products such as interiors, exterior products, doors, shelves, etc., and can be easily replaced and stored.

When used as a canvas, it has moderate strength and elasticity, so it is necessary to attach a backing such as cloth and tension the wooden frame, and feel the comfortable elasticity that can be felt when the paintbrush is applied to the canvas. Can be.

The term “for painting” as used herein includes graphic design such as lettering, posters, illustrations, and layouts for commercial use.

The method of painting is suitable for oil painting (oil painting), acrylic paint painting, Japanese painting, pastel painting, ink painting, etc.
It can be applied to other styles.

All of them have excellent adhesion to paint, and cracking and peeling have been greatly improved, maintaining the sharpness of the painting and preserving it. .

〔The invention's effect〕

As described above, by using the metal of the present invention as a base material, a color unique to the metal is obtained, and excellent flatness, or a three-dimensional effect can be obtained by intentionally partially plastically processing, and excellent strength. In addition, it is possible to obtain excellent pleasure in touch with the paintbrush, and it can be stored semi-permanently from the viewpoint of preservation and restoration, and has significantly improved the adhesion to paint, which was a major disadvantage of metal. Yes, it is extremely excellent as a conventional painting support.

In addition, it has remarkable characteristics that can prevent the occurrence of cracks, which is remarkable when using a conventional painting, particularly using a canvas.
