Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rock-colored tone-printed paper which reproduces the color and surface shape of a Japanese painting or the like drawn with a rock-colored paint, and a rock-colored hanging shaft on which the paper is mounted.

[0002]

2. Description of the Related Art Mineral pigments are used to paint granular or powdery raw minerals using colloid or the like. Japanese paintings drawn with these mineral pigments have a large number of minute irregularities with rough surfaces. Having.

[0003] Japanese paintings and the like drawn using rock paints have a unique color tone, and the above-mentioned rough surface shape creates a special texture, which is one of the factors that create the beauty of the painting. Therefore, when replicating a Japanese painting or the like drawn using rock paint, it is necessary to reproduce the rough surface state in addition to the color tone of the painting.

A technique capable of producing a reproduction having a rough surface such as a painting drawn with rock paint is disclosed in Japanese Patent Publication No. 58-58.
No. 42040 discloses this. Specifically, the technology described in this publication is to stack a surface material made of ethylene vinyl acetate copolymer resin (EVA) on a printing substrate on which a picture is printed, And hot pressing.

On the other hand, since the hanging scroll is stored in a wound state,
It must be kept from curling and cracking, and is conventionally made with a delicate combination of Japanese paper, fabric and raw glue. The drawings are painted on silk books and Japanese paper with ink, watercolors, and mud paints, and the finished ones are displayed and finished as hanging scrolls. Therefore,
It is impossible to mount a hard material such as rock paint.

[0006]

[Problems to be Solved by the Invention] Japanese Patent Publication No. 58-4204
According to the technology described in Japanese Patent Publication No. 0, the ethylene vinyl acetate copolymer resin used as the surface material has a suitably low softening point and good hot-pressure fluidity, and thus has excellent mold reproducibility. In addition, since the adhesiveness with the printing base material is good, it is possible to produce a duplicate image in which the surface irregularities of the original image touch are faithfully reproduced.

However, the above-mentioned conventional duplicate image has the following problems. (1) When stored in a rolled state for a long period of time, a large curl due to a resin layer for rock color tone processing and a crack are easily generated. (2) Ethylene vinyl acetate copolymer resin used as a surface material of rock paint tone is suitable to be rolled and unwound because it is easily scratched and may cause whitening. Absent.

[0008] For this reason, the conventional rock color tone reproduction image cannot be applied to, for example, a surface hanging to form a hanging scroll or a roll screen (roll-up blind).

The present invention has been made in view of the above-mentioned problems of the prior art, and is intended to provide a rock-colored tone-printed paper capable of realizing a rock-colored tone-reproduced image in which winding habits and cracks are unlikely to occur. The purpose is to provide.

[0010]

Means for Solving the Problems The present inventors have made a material of a printing base material on which a picture drawn with a rock paint is hardly formed, and a material which is hardly cracked, scratched and hardly curled. As a result of intensive studies on the surface material of the rock paint tone, the following composition was found to be optimal.

That is, the mineral-color-printed paper of the present invention is a mineral-color-printed paper that reproduces the surface shape of a painting drawn with mineral paint, and is composed of a feng shui paper or a senkan paper having a printing layer. It is characterized by having a transparent ionomer film layer having an uneven surface on the printing layer.

In the rock-colored printed paper according to the present invention, the thickness of the bonsai paper or the sentin paper is 50 μm to 120 μm, and the thickness of the transparent ionomer film layer is 30 μm to 60 μm.
μm is preferred.

[0013] Further, the rock paint hanging shaft of the present invention is characterized in that the rock paint tone printed paper of the present invention is attached to a backing paper and mounted.

In the rock paint hanging shaft of the present invention, the thickness of the backing paper is preferably 50 μm to 100 μm.

[0015]

Embodiments of the present invention will be described below in detail.

FIG. 1 is a cross-sectional view schematically showing the basic structure of a rock-colored printed paper according to the present invention.
Reference numeral 2 denotes a printing layer of a desired painting, and reference numeral 3 denotes a rock paint processing layer. Hereinafter, the printing substrate 1 and the rock paint processing layer 3 used in the present invention will be described.

[Printing Base Material 1] The base material is required to have the following characteristics. Be thin and soft. Since the rock paint processing layer is provided on the base material, particularly severe conditions are required for the occurrence of curl. Therefore, the material must be thin and highly flexible. The expansion and contraction is uniform throughout. For example, if the expansion and contraction when immersed in water and dried is not uniform over the whole, wrinkles are formed and the commercial value is reduced. When the shaft is mounted, it can be attached to the backing paper with low-concentration sofu paste dissolved in water. When glue is applied, it loses its suppleness, making it difficult to apply it as a hanging scroll. When the shaft is mounted, the resin should be appropriately impregnated by pasting or hot pressing. If the resin impregnates too much and the resin penetrates to the back side, the glue becomes difficult to work,
It becomes difficult to apply as a hanging scroll.

The inventors of the present invention have conducted intensive studies on materials satisfying the above-mentioned characteristics, and as a result, have found out that machine-like paper and senkan paper are the most suitable. It was decided to use it. The reason for this is that the hand-made one has a coarse fiber, and when a rock paint processing layer made of resin is provided, the resin melted by heating penetrates the fiber layer, and for example, adhesion to the backing paper at the time of shaft mounting is good. This is because it cannot be performed.

Further, for example, Torinoko No. 4, white linen paper, goose paper, and the like have the same resin penetration and are unsuitable. Also,
Art paper, coated paper and the like have excellent printability, but have a remarkable curl.

The thickness of the feng shui paper or senkan paper used as a printing substrate is preferably 50 μm to 120 μm,
About 0 μm to 100 μm is particularly preferable. If it ’s too thin,
When the rock paint processing layer is provided, the resin melted by the heating easily permeates the fiber layer, and the glue is hard to break. On the other hand, if the thickness is too large, the flexibility is reduced and the curl tends to be easily generated, and the air permeability is reduced and the air bubbles are easily generated at the time of gluing.

[Rock paint processing layer 3] The rock paint processing layer is required to have the following characteristics. Being suitable for rock paint processing. That is, it is necessary that rock paint tone processing (embossing) can be easily performed. The film must have a low internal stress. For example, in a stretched film or the like, the internal stress is large, and the curl tends to be formed. To have high transparency so that the color development of the ink of the printing layer provided on the printing substrate can be utilized. Strong against rubbing and scratching.

The inventors of the present invention have conducted intensive studies on materials satisfying the above-mentioned characteristics, and as a result, have found that an ionomer resin film is optimal, and have decided to use an ionomer resin film as a rock paint processing layer.

The ionomer resin is particularly transparent.

Roll up or roll up, especially like a hanging scroll or roll curtain.
It is suitable for use after unraveling. Also,
Ionomer resin is used for printing paper
Easy control of the degree of impregnation into paper
Excellent adhesion to

The ionomer film used as the rock paint processing layer preferably has as little stretching as possible. For example, a non-stretched film such as an inflation film is preferable.
The thickness is 30 μm especially when the shaft is mounted.
To 60 μm, preferably 35 μm to 50 μm
The degree is particularly preferred. If it is too thin, the embossing of the rock color tone processing becomes shallow, making it difficult to obtain the desired rock color tone effect. On the other hand, if the thickness is too large, the flexibility is reduced, and the curl and cracks are easily generated.

Incidentally, an ethylene-unsaturated fatty acid copolymer resin film such as an ethylene-methacrylic acid copolymer (EMAA) has characteristics similar to an ionomer resin film, and particularly, a non-stretched film such as an inflation film. Can be used as the transparent film of the mineral pigment processing layer of the present invention.

In the production of the mineral-colored printed paper of the present invention, for example, a work such as Japanese painting is printed on a printing substrate by offset printing or the like, and an ionomer resin film is placed on the substrate and heated and pressed. After laminating, the ionomer resin film can be formed by subjecting the ionomer resin film to a plurality of rock-paint-like irregularities by a conventionally known method. In the step of laminating the ionomer resin film on the base material and the unevenness processing step, the heating and pressurizing conditions are appropriately adjusted so that the film does not reach the back surface of the printing base material because the film is excessively melted. It is preferable to make them adhere. This allows
When the rock color tone print-processed paper of the present invention is applied as a work to backing paper with glue, adhesion to the backing paper can be performed well.

In the rock-colored printed paper of the present invention configured as described above, the printing layer 2 expresses the color tone two-dimensionally, and the numerous fine irregularities 4 formed on the surface of the rock-colored processed layer 3. Expresses the rough surface shape peculiar to rock paint, and these work together to express the beauty of Japanese painting and the like by rock paint.

The rock paint adjusting shaft of the present invention is obtained by sticking the above-described rock paint tone printed processed paper of the present invention on a backing paper 5 as shown in FIG.

In general, a hanging scroll is a work in which a painter or calligrapher draws a piece of work on Japanese paper or silk fabric and the finishing work is finished as a shaft by a painter. The rock paint adjusting hanging shaft of the present invention is also a rock paint of the present invention. It can be configured in the same manner as a conventional hanging scroll, except that tone-printed paper is used as a work.

The backing paper used for the rock paint hanging shaft of the present invention is not particularly limited as long as it is Japanese paper. The thickness of the backing paper is preferably 50 μm to 100 μm. . If the thickness is too thin, it is difficult to obtain the strength as a hanging shaft. If the thickness is too thick, the flexibility is reduced and the curl tends to occur.

Further, in the conventional hanging scroll, the backing paper (backing paper) generally has a two-layered structure of the back side and the entire back side. Enhance
In order to prevent the curl, it is preferable to eliminate the back of the skin and use only the entire back.

Then, by peeling the bonded product from the mold, a printed material subjected to the rock color tone reproduction unevenness processing is completed, and a rock color tone printed processed paper is obtained.

Next, the rock color tone print-processed paper was mounted on the shaft to prepare a rock color tone hanging shaft. This manufacturing process will be described.

Unnecessary portions other than the pattern of the rock-colored tone-printed paper are cut, and then water-applied to the plate with the surface (printing surface) down using a brush. Next, a paste dissolved in water was brush-painted on a backing paper (handmade Japanese paper using thin-mouthed mulberry paper) larger than that size, and this was adhered from the paste surface. The surface of the paper was spread well with a brush to release air bubbles and left as it was. The shaft was mounted using ordinary materials and operations.

(Comparative Example) Art paper (90
kg / 46 size), and using a rock paint tone printed paper and a rock paint tone in the same manner as in the above example, except that an EVA film (60 μ thickness) was used as a transparent layer for applying a rock paint tone reproduction unevenness process. A paint hanging shaft was produced.

The rock-colored printed paper produced in Examples and Comparative Examples was evaluated for abrasion resistance. Table 1 shows the results. In the gakushin-type abrasion resistance test, high quality paper (90 kg / 46 size) was laid on rock-colored printed paper, and rubbed from above with a 200 g weight.

[0042]

[Table 1]

As shown in Table 1, the rock-colored tone-printed paper of the example is more excellent in abrasion resistance than that of the comparative example. Further, the ionomer film used in the examples had higher transparency than the EVA film, and the rock color tone-printed paper of the examples was a product having a sharper and deeper feeling than that of the comparative example.

When the rock paint hanging shafts produced in Examples and Comparative Examples were rolled up and stored at room temperature for one month at room temperature and unraveled, the rock paint hanging shafts of the examples according to the present invention were found to be No curls or cracks at a level that hindered the commercial value were found. On the other hand, in the conventional one, the winding habit remained and some cracks occurred, and the commercial value was low.

[0045]

As described above, according to the rock-colored tone-printed paper of the present invention, it is possible to realize a rock-colored tone-reproduced image in which winding habits and cracks are unlikely to occur. It can also be applied to screens (roll-up blinds) and the like.

In addition, since the product value does not decrease even if it is stored in a rolled-up state, compact storage is possible.
The work can be made larger.

Further, according to the rock paint hanging shaft of the present invention, it is possible to provide a hanging shaft of a rock paint tone duplicated image which has a very high commercial value and has never existed before.
