Description

Description: TECHNICAL FIELD The present invention relates to a transfer material capable of expressing a glossy surface and an uneven surface on a transfer surface by a one-step transfer processing, and a manufacturing method thereof.

<Prior Art> A pattern having a glossy surface and an uneven surface, for example, a pattern in which a glossy surface and a matte surface coexist, or a pattern in which a glossy surface and a hairline surface or a spin surface coexist, etc., can be transferred in one step. The following are transfer materials to be expressed on the surface to be transferred. That is, on a substrate sheet whose hairline processing or spin processing has been applied to the entire surface by a physical processing method of scratching the surface with sandpaper or a non-woven fabric, or the surface of which has been delustered by processing such as sandblasting or chemical etching. It is a transfer material in which a resin layer is formed in the part where a glossy surface is to be formed, the irregularities of the base sheet in that part are filled with resin to make a smooth surface, and then a pattern layer, an adhesive layer, etc. are sequentially laminated on it. .

In addition, an opaque resin layer mixed with an additive such as an extender pigment is formed by a printing method at a portion where a matte surface is to be formed on a plastic film having a glossy surface, and a pattern layer or an adhesive layer is further formed thereon. Is a transfer material in which

<Problems to be Solved by the Invention> However, the above transfer material has the following drawbacks.

In the former transfer material, it was difficult to completely fill the unevenness with the resin layer, and the unevenness was inevitably left (see FIGS. 6 to 7). This is because the resin layer has to be thicker than the depth of the unevenness, but the resin has fluidity, so that there is a limit in filling the unevenness of the base sheet. Therefore, in this transfer material, the depth of the unevenness was limited to a relatively shallow depth, and the design effect of what should be a hairline surface or a matte surface was small.

In the latter transfer material, the depth of unevenness is regulated by the particle size of the extender pigment or the like (see FIGS. 8 to 9), and among these, those having printability are limited to those having a relatively small particle size. Therefore, even with this transfer material, the design effect of what should be a matte surface was small. Also,
As a matter of course, the uneven shape could only express the matte surface.

Therefore, an object of the present invention is to solve the above-mentioned drawbacks, and to obtain a transfer material capable of expressing a glossy surface and an uneven surface on a transferred surface by a one-step transfer processing, and a manufacturing method thereof. .

<Means for Solving Problems> In order to achieve the above-mentioned object, the present invention has been performed as follows. That is, the transfer material capable of expressing a glossy surface and an uneven surface, which is the first invention, is provided with a release layer having an uneven surface on the base sheet except the portion where the mask layer is provided, A surface layer which is peeled off but is not peeled off from the mask layer is provided, and further, an adhesive layer is provided on the surface layer.

A second aspect of the present invention is a method for producing a transfer material capable of expressing a glossy surface and an uneven surface, in which a release layer adhered to the base sheet is provided on the entire surface of a base sheet having a smooth surface. A mask layer that can be peeled from the release layer is provided on the top surface, and the surface on which the mask layer is provided is subjected to uneven processing, and a surface layer that is peeled from the release layer but not from the mask layer is provided on the mask layer. Further, an adhesive layer is further provided on this.

<Operation> In the transfer material of the present invention, the base sheet is in close contact with the release layer. Further, the release layer is separated from the mask layer and the surface layer. Further, the mask layer and the surface layer, and the surface layer and the adhesive layer are in close contact with each other. Further, the adhesive layer and the transfer-receiving body are brought into close contact with each other by transfer processing. Therefore, when the transfer material of the present invention is superposed on the transfer target and subjected to transfer processing by a method such as heating and pressing, and then the base sheet is peeled off together with the release layer (see FIG. 5), the transfer material is transferred. Except for the base sheet and the release layer, the constituent layers are in close contact with the transferred material, and the release layer is separated from the mask layer and the surface layer. Therefore, the mask layer portion has a smooth surface shape, and the portion other than the mask layer, that is, the surface layer portion has an uneven surface shape.

<Example> Hereinafter, the present invention will be described in more detail with reference to the drawings.

FIG. 1 is a sectional view showing an embodiment of the transfer material of the present invention. 2 to 4 are sectional views showing the manufacturing process of the present invention. Reference numeral 1 is a base sheet, 2 is a mask layer, 3 is a surface layer, 4 is an adhesive layer, 5 is a colored layer, and 6 is a metal layer.

First, the transfer material of the first invention will be described.

As the material of the base sheet 1, a plastic film similar to that used for a normal transfer material such as polyethylene terephthalate / polypropylene / cellophane is used.

The release layer 2 adheres to the base sheet 1 and separates from the mask layer 3 and the surface layer 4. As the material, a thermoplastic resin such as an acrylic resin / vinyl chloride resin, a curable resin such as a melamine resin / urethane resin / epoxy resin, an ultraviolet curable resin, an electron beam curable resin, or the like is used.

The mask layer 3 is peelable from the release layer 2 and is in close contact with the surface layer 4, and when the surface of the release layer 2 on which the mask layer 3 is provided is subjected to uneven processing, the unevenness is masked. This is for preventing the part covered with the layer 3 from reaching the release layer 2. The mask layer 3 is provided on a portion where a glossy surface is desired to be provided, and it may be colored or uncolored (see FIG. 2). As its material, acrylic resin
Thermoplastic resin such as vinyl chloride resin, curable resin such as melamine resin, urethane resin and epoxy resin, ultraviolet curable resin, electron beam curable resin and the like are used.

Note that the mask layer 3 may or may not have irregularities on the surface layer 4 side. The unevenness is formed depending on the degree of resin hardness of the mask layer 3 when the unevenness processing is performed on the surface of the release layer 2 on which the mask layer 3 is provided.
That is, when the resistance of the mask layer 3 is extremely high, the mask layer 3 is smooth, and when the resistance is poor, deep unevenness is formed. In any case, it is sufficient that the release layer 2 has no unevenness.

The surface layer 4 is peelable from the release layer 2 and is in close contact with the mask layer 3. If the mask layer 3 has irregularities, the surface layer 4 fills the irregularities and is in close contact with the mask layer 3 to be integrated with the mask layer 3. Therefore, when the mask layer 3 has irregularities, the irregularities are made invisible. As a material suitable for the surface layer 4, it is necessary to adhere to the mask layer 3, and therefore, a resin of the same system as that used for the mask layer 3 is preferable. The surface layer 4 may be colored or uncolored.

The adhesive layer 5 is in close contact with the surface layer 4 and also in contact with the transfer target during transfer processing. As the material, chlorinated olefin, chlorinated rubber, acrylic resin, polyester resin or the like is used depending on the material of the transferred material (see FIG. 4).

Furthermore, it is also possible to provide the coloring layer 6 between the surface layer 4 and the adhesive layer 5, or to provide the metal layer 7 between the surface layer 4 and the adhesive layer 5 in whole or in part. By combining them, the design effect can be enhanced (see FIG. 1). When the metal layer 7 is provided, an anchor layer may be provided before and after the metal layer 7 according to a conventional method for providing the metal layer in the transfer material.

Next, a method of manufacturing the transfer material according to the second aspect of the present invention will be described.

First, the release layer 2 is provided on the entire surface of the base sheet 1. As the method, an ordinary printing method such as a gravure coating method or a roll coating method may be used.

Next, the mask layer 3 is provided on the part of the release layer 2 where the glossy surface is to be provided (see FIG. 2). As the method, there are methods such as printing, painting and pasting, but the printing method is preferable because the mask layer 3 must be patterned.

After forming the mask layer 3, the surface of the release layer 2 on which the mask layer 3 is provided is processed to be uneven. As the uneven processing, there are hairline processing and spin processing by a physical method of scratching the surface with sandpaper or non-woven fabric, or matting processing by a physical or chemical method such as sandblasting and chemical etching (see Fig. 3). ).

The surface layer 4 is provided on the surface of the release layer 2 on which the mask layer 3 is provided by a printing method, a roll coating method, or the like.

The adhesive layer 5 is provided on the surface layer 4 by a printing method, a roll coating method, or the like. (See FIG. 4).

Further, in order to enhance the design effect, the colored layer 6 and the metal layer 7 may be provided entirely or partially before the adhesive layer 5 is provided (see FIG. 1).

The colored layer 6 may be provided by a usual printing method such as screen printing or gravure printing.

The metal layer 7 can be formed of a metal such as aluminum or chromium / nickel by a vacuum deposition method, an ion plating method, a sputtering method, or the like. Also the metal layer 7
In the case of partially providing the metal pattern, a water-soluble resin layer is formed on a portion that does not require a metal pattern, a metal layer is formed on the entire surface from above, and water washing is performed to remove the unnecessary metal layer together with the water-soluble resin layer. There are ways to do it. When the metal layer 7 is provided, the metal layer 7 is formed according to a conventional method of providing the metal layer in the transfer material.
Anchor layers may be provided before and after.

Through the above steps, it is possible to manufacture a transfer material capable of expressing a glossy surface and a concavo-convex surface on the transferred surface by one-step transfer.

<Effect of the Invention> According to the first invention, the transfer material of the present invention has a mask layer, the mask layer and the release layer are smooth, and the surface layer and the release layer are between. Since the unevenness is formed, when the release layer is peeled off together with the base sheet after the transfer processing, the part where the mask layer exists forms a glossy surface, and the other part forms the uneven surface, which is transferred in one step transfer. A glossy surface and an uneven surface can be expressed on the surface, no unevenness appears on the glossy surface, and the uneven surface has a sufficient depth and can take various forms.

According to the second invention, the manufacturing method of the transfer material of the present invention is
Since the unevenness processing such as hairline processing and matte processing is performed after the mask layer is provided, the mask layer prevents unevenness from extending to the base sheet and forms an uneven surface and a glossy surface on the base sheet. During transfer processing, the base sheet peels off from the mask layer together with the release layer to form a surface, and no unevenness appears on the glossy surface, and the uneven surface has a sufficient depth and can take various forms. Is.
