Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laminated body in which a colored portion is formed on a synthetic resin thin film surface formed on a release paper by using a copying machine, for example, a colored pattern such as shoes, bags and sheet-like bodies. And a manufacturing method thereof.

[0002]

2. Description of the Related Art Conventionally, printing of a material such as a bag, a bag material or a footwear material such as shoes is generally performed by printing. Various methods such as gravure, offset, and screen can be used as this printing method, but in any case, a roll, a plate, a screen, etc. are required, and the expression is not simple and the printing is not simple. The technology is inherently suitable for high-volume production, not for low-volume, high-mix production. Therefore, the transparent base paper is cut into the size of the original image, the ink of the printed matter is heat-bonded to this transparent base paper with a special machine (transcopy machine), and then this transparent base paper is put into the pulp dissolving liquid to remove the pulp on the back side. A known method is to scrape off, heat the adhesive to the ink side of the transparent base paper, trim it to the desired part, and finally put the original image on the adherend (base material) and heat bond with a transcopy machine. ing. This method is suitable for the production of a large variety of products in small quantities, but requires many steps as described above.

On the other hand, in the invention described in JP-A-64-19360, a transfer method using a copying machine is proposed. This method is also suitable for the production of a wide variety of products in small quantities.First, a paper consisting of a film, a silicon resin layer formed on the surface of the film, and a synthetic resin paint layer is used as copy paper, and the surface of the synthetic resin paint layer is used. Then, a toner layer is formed by copying with a copying machine. next,
After the toner layer and the surface of the adherend (base material) are brought into contact with each other and heated and pressure-bonded, the film and the silicone resin layer are peeled off from the base material side to form a toner layer and a synthetic resin coating layer on the base material. Are formed. However, in the case of coloring the surface of a base material used for bags, shoes, etc., extremely high durability is required, and the method of the invention described in JP-A-64-19360 described above may give unsatisfactory results. could not. In particular, in the case of a color copy, the toner is mainly composed of styrene-acrylic copolymer resin, so if a clear color copy is to be obtained when copying with a copying machine, a synthetic resin coating layer to be the surface to be copied. It becomes necessary to use a material having a high affinity with the styrene-acrylic copolymer resin as the material. Examples of such a resin include a hot-melt type olefin-based resin and an ethylene / vinyl acetate copolymer resin. However, this type of resin has weak bending resistance and insufficient heat resistance, and is not suitable for bags and If it is used for a base material such as shoes, the resin layer may be damaged, and even the toner layer may be damaged, and the coloring may come off. Further, the styrene / acrylic copolymer resin for the toner layer has a characteristic of being hard but extremely brittle, and sufficient flex resistance cannot be obtained by forming only one layer on the surface of the toner layer. In addition, in recent years, in addition to copying using toner, development of a copying machine using an inkjet method has been underway. In the case of this inkjet method, a water-based or solvent-based dye is used as an image forming agent, and in this case also, as in the case of the above-mentioned toner, good coloring, bending resistance, and heat resistance are obtained. It is necessary to satisfy various requirements such as.

[0004]

Therefore, the present invention is capable of vivid coloring using a copying machine and is flexible enough to be used as a surface coloring pattern layer of a substrate such as a bag or shoes. And a laminate having a high heat resistance strength, which can be used by being processed into a product having an appropriate shape such as shoes, bags and sheets, and a method for producing the same.

It is intended to provide a laminate having a colored portion using a machine. According to a second aspect of the present invention, there is provided a release paper, a synthetic resin first thin film formed on the release surface, and a synthetic resin second thin film formed on the surface of the first thin film. The first thin film has higher bending resistance and heat resistance than the second thin film, and the second thin film is the first thin film.
Higher affinity for image forming agents such as toner compared to thin films,

The present invention provides a method for manufacturing a laminate using a copying machine. Further, in the second invention, the image forming layer such as the toner of the paper and the surface of the substrate are brought into contact with each other and bonded by heating and pressing, and then the release paper is removed. is there. A fourth invention is a release paper,
A paper having a second thin film made of a synthetic resin formed on the release surface is prepared, and an appropriate image is copied on the surface of the second thin film of the paper by a copying machine, so that toner or the like can be removed. After the image forming layer is formed and the second thin film of this paper and the surface of the substrate are joined by heating and pressing, the release paper is removed, and further, on this second thin film, in comparison with this second thin film. It is intended to provide a method for producing a laminated body using a copying machine in which a first thin film made of a synthetic resin having high bending resistance and heat resistance is formed by post-processing. Furthermore, a fifth aspect of the present invention uses a sheet-shaped body as the base material according to the second to fourth aspects of the invention, and after the above-mentioned lamination is completed, the laminated body is formed into a product of an appropriate shape such as a shoe or a bag. The present invention provides a method for manufacturing a laminated body using a copying machine, which is characterized by processing.

Hereinafter, the present invention will be described in more detail with reference to the drawings. First, FIGS. 1 to 6 show a method according to the second to third inventions. As the first step, the paper 1 shown in FIG. 1 is prepared. This paper 1 is a release paper 2
And the first thin film 3 made of synthetic resin formed on the release surface
It is a sheet provided with a and a second thin film 3b made of synthetic resin formed on the surface of the first thin film.

The release paper 2 comprises a support layer 2a made of an appropriate material such as paper or synthetic resin, and a release layer 2b formed on at least one surface thereof. The release layer 2b has a first
A material having a good releasability from the thin film 3a, for example, a silicon resin or the like can be used. As the release paper 2, it is necessary to use one having strength and heat resistance that can withstand the heating and pressing in the final joining step. Further, when the first and second thin films 2a and 2b are formed by coating, it is necessary to have strength that can withstand the coating work without being attacked by the solvent in the synthetic resin composition of these thin films.

The first thin film 3a is transparent or semi-transparent,
The surface layer of bags, shoes, etc. is composed of a component having a degree of flex resistance that can withstand. Specifically, polyurethane obtained by the reaction of a polymer diol, an organic polyisocyanate and a chain extender, an amino acid-modified polyurethane, an organopolysilicon Examples thereof include polyurethanes having a noxyl group, polyester elastomers, copolymerized polyamides, modified polyamides, soft fluorine-based resins, polyvinyl chloride, acrylic acid ester copolymers, and the like, or a mixture thereof.

The second thin film 3b is transparent or translucent and is a component having a good affinity with an image forming agent such as a color toner of a copying machine or an inkjet dye, and further, the first thin film 3a and a later-described component. It is preferable to use a material having a good affinity with the base material 5. Specific examples include EVA (ethylene / vinyl acetate copolymer resin), olefin copolymer resin, polyamide resin, copolymer polyester resin, acrylic copolymer resin, and the like.

These thin films may be laminated on the release paper 2 by an appropriate means such as a laminating method, but the coating method is preferable from the viewpoint of ease of construction. As a coating method, a brush coating, a spatula coating, a roll coater, a knife coater, a reverse coater, a curtain flow coater, or the like can be adopted as appropriate, and the resin is dissolved in a solvent and applied to the surface of the release layer 2b of the release paper 2. After that, it is formed by evaporating the solvent. Alternatively, the film can be formed by a melt thin film method. The solvent may be appropriately selected and used, but it is required that it can dissolve each resin and does not attack the release layer 2b. If necessary, a coloring agent may be added to the extent that the transparency of each thin film is not impaired, or an appropriate additive such as an ultraviolet absorber, a surfactant or a matting agent may be added.

The thickness and size of this paper can be freely changed within a range having a thickness and size suitable for use as copy paper of a copying machine. When the first and second thin films are formed, they may be continuously processed into a long shape and cut into an appropriate size with a cutter or scissors.

Next, on the surface of the second thin film of the paper 1,
The image forming layer 4 is formed by copying an appropriate original image with a copying machine (FIG. 2). As the copying machine, a commercially available electronic copying machine such as a toner method or an ink jet method can be used, and a single color copy of black alone may be used in addition to a color copy of a plurality of colors. The material of the color copy toner differs depending on the electronic copy maker, but each company generally uses a styrene-acrylic copolymer resin. There is no special condition as long as the original image can be copied by an electronic copying machine such as printed matter or photographs, but it is mirror-symmetrical when transferred to the substrate in the next step, so be especially careful in the case of letters etc. Requires.

Next, the image forming layer of the paper 1 is brought into contact with the surface of the base material 5 made of an appropriate material such as synthetic resin and bonded by heating and pressing (FIG. 3). As the base material 5, synthetic leather (vinyl chloride-based leather, artificial leather), natural leather, woven cloth, knitted cloth, non-woven cloth, synthetic resin sheet, or other appropriate material can be used. As a joining method by heating and pressing, a pressing method, a laminating method, or the like can be adopted, and pressing may be performed simultaneously with heating from both sides or one side, or pressing may be performed after heating. The joining method can be appropriately selected and carried out.

After the joining is completed, the release paper 2 is removed (FIG. 4). By this, the transfer is completed, and the laminated structure is formed on the surface of the substrate 5 in the order of the image forming layer 4, the second thin film 3b, and the first thin film 3a. Therefore, on the outermost surface of this substrate, the first
Since the thin film 3a is coordinated, the transferred image can be protected with sufficient mechanical strength such as bending resistance and heat resistance strength even if it is used severely as a shoe or a bag.

When it is desired to form unevenness on the surface of the base material, the unevenness may be formed on the heating and pressurizing mold used in the above-mentioned joining process, and this may be transferred to the base material simultaneously with the joining. However, as shown in FIG. 5, the release paper 2 may be embossed to form irregularities. With this, without forming irregularities on the mold for heating and pressing,
The unevenness of the release paper 2 is transferred to the base material 5 at the time of heating and pressing, and the unevenness can be transferred to the surface of the base material at the same time when the image is transferred (see FIG. 6), and two types of transfer are performed in a single step. It is possible and extremely advantageous.

The substrate on which the transfer has been completed may be directly processed into shoes or bags, or may be further dyed. In this case, it is preferable to select, as the material of the first thin film 3a, a material having a good fixing property of the stain.

Next, FIGS. 7 to 11 show a method according to the fourth invention, that is, a method of forming the first thin film by post-processing. As the first step, a sheet 1'shown in FIG. 7 is prepared. This paper 1'is a paper provided with a release paper 2 and a second thin film 3b made of synthetic resin formed on the release surface. The release paper 2 and the second thin film 3b are
The same method as described above can be used, and the second
The method of laminating the thin film 3b on the release paper 2 can also be carried out by the same method as described above.

Next, the image forming layer 4 is formed on the surface of the second thin film of the sheet 1'by copying an appropriate original image by a copying machine (FIG. 8). The conditions of the copying machine and the like can be the same as the above-mentioned method.

Next, the image forming layer of the paper 1'is brought into contact with the surface of the substrate 5 made of an appropriate material such as synthetic resin,
Bonding is performed by heating and pressing (FIG. 9). This joining can be performed by the same method as that described above.

After the joining is completed, the release paper 2 is removed (see FIG. 1).
0). By this, the transfer is completed, and the laminated structure is formed on the surface of the substrate 5 in the order of the image forming layer 4 and the second thin film 3b.

Next, the first thin film 3 is formed on the second thin film 3b.
a is formed (FIG. 11). As the first thin film, the same one as in the above-mentioned method can be used. The first thin film 3a is coordinated on the outermost surface of the base material, so that it is transferred with sufficient mechanical strength such as flex resistance and heat resistance strength even if it is used severely as a shoe or a bag. You can protect the image. The first thin film may be laminated on the second thin film by an appropriate means such as a laminating method.
From the viewpoint of ease of construction, coating method, especially spray,
The flow coating method is advantageous. In addition, a coloring agent may be added if necessary so long as the transparency of each thin film is not impaired,
Alternatively, an appropriate additive such as an ultraviolet absorber, a surfactant or a matting agent may be added. In the case of forming irregularities on the surface of the base material, it may be performed during the above-mentioned joining step or after forming the first thin film. Further, after forming the first thin film, further dyeing may be performed. in this case,
As the material of the first thin film 3a, it is preferable to select a material having a good fixability of the stain.

The sheet-shaped base materials laminated by each of the above methods are processed into products such as shoes and bags by known methods such as cutting and sewing.
