ている。A typical aspect of a coating method conventionally used for coating the plate-shaped material with an ultraviolet curable resin coating material is as follows. That is, for example, on a plate surface of a plate-shaped material made of lauan plywood, first, a commercially available aqueous colorant or the like is applied by spraying or brush coating with a spray gun to give a desired color, and then a commercial undercoat Apply UV curable resin paint by spraying or brushing in the same way,
A commercially available ultraviolet irradiator (for example, "Saran UV hand device": trade name: manufactured by Saran International Co., Ltd.) is used to apply ultraviolet rays in seconds (usually about 5 to 30 seconds).
In order to enhance the texture and to stabilize the fixing of the paint applied to the coating film surface, paper (paper file) or sand blast is applied to the surface of the undercoat film to form a coating film surface by irradiating with The surface area of the coating film is increased by sanding with a sandpaper, etc., and then using a commercially available UV curable resin coating for intermediate coating, sanding is performed in exactly the same manner as above. The final coating film surface is formed, and finally, a commercially available UV-curable coating material for top coating is applied by spraying or brushing, and the coating film surface is formed by irradiating with ultraviolet rays and drying and curing, if necessary. In addition, a polishing process is further applied to form a mirror-finished coating surface. The above-mentioned coating method is usually carried out in an environment such as a clean room where dust and dirt are avoided.

しても極めて容易に剥離できる。The most characteristic feature of the present invention is that the state of the film surface is reproduced as it is on the coated surface by combining the ultraviolet curable resin coating material and the film. Normally, furniture and furniture are painted with natural drying type paints such as lacquer, lacquer, and enamel.These coatings begin to dry and harden immediately, but UV-curable resin paints are exposed to UV rays. It does not cure until irradiated. Therefore, since the coating film surface of the ultraviolet curable resin coating material has fluidity before being irradiated with ultraviolet light, the state of the film surface (fine rough surface or smooth surface) brought into contact with this is fluid.
Can be reproduced as it is, as if the state was transferred. Also, peeling between the coating surface and the film surface after curing by ultraviolet irradiation is easy because the coating surface is cured, and the state reproduced on the cured coating surface (fine rough surface) Or smooth surface) is not damaged. Depending on the material of the plastics film, it may be difficult to peel off during repeated use, but when it is made of polypropylene, it can be peeled off very easily even if it is repeatedly used.

In some cases, the mirror-coated surface where the smooth surface is reproduced is
Both can be formed elegantly for a short time. Further, in the present invention, since the paint is spread on the surface to be coated with the film covered, the influence of dust and dust can be avoided as much as possible.

Example 1 A plate-shaped material (horizontal surface) made of lauan plywood was spray-painted with a water-based coloring material to give an all-nut color (see FIG. 1). The plate-like material corresponding to the colored plate surface on the surface finish 1 m 2 per 80g amount of undercoat for the ultraviolet curable resin coating material (undercoat 110UV: Product Name:
A clay-like lump of Saran International Co., Ltd. is placed, and a thickness of 188 is obtained by sandblasting (grain size 80 mesh) on the entire surface of which fine irregularities are roughened.
A transparent film made of polypropylene having a thickness of μm was brought into contact with the film, and the hard rubber roller was evenly rolled over the film to spread the above lumps to form a paint layer having a thickness of about 50 μm (see FIGS. 2 and 3). ). Then, from the outer surface of the film, an ultraviolet irradiator (Saran UV hand device: product name: Saran
In accordance with a conventional method, an ultraviolet ray was irradiated for about 8 seconds to cure the above paint layer, and then the film was peeled off to form a first matte coating surface (see FIG. 4). In addition, it was confirmed by visual observation using a magnifying glass that the roughened state of the film used was exactly reproduced on this coated surface. Then, intercoat ultraviolet-curable resin coating material (undercoat 26 in an amount corresponding to the finish surface 1 m 2 per 130g onto the matt coating surface
0UV: product name: made by Saran International Co., Ltd., a clay-like lump placed on it, and made of polypropylene with a thickness of 188 μm, which has been roughened with fine irregularities on the entire surface by sandblasting (grain size 160 mesh) A transparent film is brought into contact, and the agglomerates are spread in the same manner as above to form a paint layer having a thickness of about 100 μm (see FIGS. 5 and 6).
Then, in the same manner as above, the coating layer was cured by irradiating it with ultraviolet rays for about 10 seconds, and then the film was peeled off to form a second matte coating surface (see FIG. 7). It was confirmed in the same manner as above that the roughened state of the film used was reproduced on this coated surface as it was.

The plate-like material corresponding to surface finish 1 m 2 per 60g on matte coating film surface amount of topcoat for UV-curable resin coating material (over hardcoat 4
60UV: Product name: Saran International Co., Ltd.)
The clay-like lump of No. 1 was placed, and a polypropylene transparent film of 188 μm in thickness, which had been roughened with fine irregularities on the entire surface by the sand blast method (grain size 180 mesh), was brought into contact with it, and the same as Example 1. Then, the above lump is spread to form a coating layer having a thickness of about 40 μm, and then the coating layer is irradiated with ultraviolet rays for about 5 seconds to cure the coating layer in the same manner as in Example 1, and then the film is peeled off. Example 1 shows that a matte coating film surface is formed on the coating film surface, and the rough surface state of the film used is reproduced on this coating film surface as it is.
It was confirmed in the same manner as. The matte coating film surface obtained here had a so-called "depth" and was rich in luxury.

Clay-like lumps of the same paint as in Example 2 were placed on the surface of the flat coating material of the plate-like material in the same amount as in Example 2, and a thickness 18 having a smooth surface was placed on the clay-like lump.
A polypropylene transparent film having a thickness of 8 μm is brought into contact with the lump, and the lump is spread in the same manner as in Example 1 to give a thickness of about 40 μm.
Coating layer is formed (see FIGS. 8 and 9), and then the coating layer is irradiated with ultraviolet rays for about 5 seconds to cure the coating layer, and then the film is peeled off to form a smooth coating surface. (See Figure 10). It should be noted that the smooth surface of the film used is reproduced exactly as it is on the surface of this coating film.
It was confirmed in the same manner as. The coating film surface obtained here had the same level as the state of the coating film surface, which is called a mirror finish in high-end furniture, and was rich in high-class feeling.
