DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a decorative member used for, for example, various nameplates and display boards, and particularly to a decorative member suitable for giving a three-dimensional appearance to a display portion.

[0002]

2. Description of the Related Art Conventionally, as a method for manufacturing a decorative member in which a display portion is provided with a three-dimensional effect or a raised display effect of an uneven shape,
The method described in JP-B-8-9279 is known.

In this manufacturing method, a colored coating such as black is printed and formed on a surface of a display sheet made of aluminum foil except for a part of the surface, and a display portion in which the metal color of the foil surface is exposed in a non-colored portion is formed. After the formation, a resin coating layer is formed on the foil surface, and then the embossing is performed to make the display portion convex, and after embossing, a transparent synthetic resin liquid or the like is applied in such a manner as to cover the entire display sheet. It is to be poured and cured to form a transparent coating layer having a middle and high buildup.

According to this manufacturing method, there is an advantage that a decorative display function having a three-dimensional effect on the display unit can be obtained by a relatively simple manufacturing process.

Further, as another method of manufacturing a decorative member having a three-dimensional display portion, there is known a method in which a sheet-like substrate made of a PET material or the like is plated with a metal color or the like and then etched. ing.

Further, as another method of manufacturing a decorative member having a three-dimensional display portion, back printing is performed twice or more on the back surface of a sheet-like base material such as a transparent PET material, so that the back printing is not performed. It is also known that by forming a relative recessed portion on the portion and laminating a metal color film material on this recessed portion, the metal color portion can be seen from the surface of the base material when viewed from the surface of the base material. I have.

[0007]

However, in the method of embossing a display portion consisting of a non-colored portion to have a convex shape, it is necessary to make the mold strictly conform to the display portion at the time of embossing. There was a drawback that the alignment work was very troublesome. Moreover, each time the configuration of the display portion is changed, a new mold for embossing has to be manufactured, which is not suitable for the production of various kinds of small decorative members. Moreover, the display sheet, which is the base material, must be made of a material capable of forming irregularities by embossing. Therefore, the material used for the display sheet is limited to aluminum foil or the like, and it is difficult to form irregularities. It was difficult to manufacture a decorative member using a base material of a material.

Further, in the method of etching a metal sheet or the like after plating on the surface of the sheet-shaped substrate, it is difficult to form a plating layer into a thick film, so that a three-dimensional display effect is poor. Since it is necessary to take measures to prevent the display portion from being etched in the etching step, it is troublesome and troublesome.

Further, in the method of laminating a metal-colored film material on the concave fitting portion formed on the back surface of the base material, a deep concave fitting portion must be formed in order to obtain a high stereoscopic display effect. Had to be overprinted four or five times, which was inefficient and costly.

The present invention has been made in view of such a technical background, and it is possible to generate a three-dimensional effect on a display unit, but also to emboss, etch, or fit a concave on the back surface of a substrate. It is an object of the present invention to provide a method for manufacturing a decorative member having a three-dimensional display portion that does not require formation of a part, can be mass-produced, and is inexpensive.

[0011]

The object of the present invention is to form an adhesive resin layer on a surface of a base material in a desired pattern, and to press a transfer material having a transfer component on the surface of the resin layer. And a step of attaching a transfer component of the transfer material to the surface of the resin layer by utilizing the adhesive force of the resin layer.

According to this manufacturing method, the convex display portion is formed by the processed resin layer, so that not only the stereoscopic display effect similar to the conventional one is obtained but also the display portion is formed in a convex shape. Since the step of embossing the base material is not required, the positioning of the stamp and the display unit at the time of stamp molding is not required, and the production of the stamp itself is not required.
In addition, the base material may be made of a material that is difficult to form irregularities, and it is not necessary to deform the base material. In this respect, there is no limitation on the material of the base material.

Further, since neither etching nor formation of a recessed portion on the back surface of the base material is required, measures for preventing etching of the display portion and repetitive overprinting for forming a deep recessed portion are not required.

Further, by pressing the transfer material against the surface of the resin layer to transfer the transfer components to the surface of the resin layer using the adhesive force of the resin layer, the display portion is displayed in a predetermined color or the like. The work for making it easy is also facilitated.

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described with reference to an example in which a small decorative member such as a nameplate or a display board is manufactured.

FIG. 1 shows a decorative member manufactured according to the present invention. The decorative member has a display portion (10) formed on a base material (1) having a predetermined shape. The production of this decorative member is performed as follows.

First, a substrate (1) is prepared. Base material (1)
Can be selected irrespective of whether or not embossing is possible, and may be a soft material or a hard material as long as it can secure adhesion to the resin. Further, the thickness is not limited, and may be a foil shape such as an aluminum foil, a sheet shape, or a block shape. The substrate (1) may be flat or may have a curved surface. Further, the base material (1) may be cut or punched to the size of the final product, or a large piece of material may be prepared and a large number of display portions (10) may be provided thereon. After forming, the product may be cut or punched into a product.

Next, if necessary, as shown in FIG. 2, the surface of the substrate (1) is colored to a desired color by printing or the like. In FIG. 2, (2) is a printing layer. Again,
It is not necessary to perform printing while leaving the display unit scheduled portion, and printing may be performed over the entire surface.

Next, an adhesive resin is applied to the surface of the base material (1) in a character, figure or other desired pattern to be displayed. It is preferable to apply the coating in a thick convex shape in that a higher three-dimensional display effect or a raised display effect can be obtained. Considering mass productivity, it is preferable to apply the coating by printing means such as screen printing. Moreover, according to the screen printing, there is an advantage that the degree of the buildup of the resin layer can be adjusted. However, you may apply by potting or other methods instead of screen printing.

After the application, the resin is cured to obtain a resin layer (3) having a predetermined pattern (shown in FIG. 2). The cured resin layer (3) must have tackiness. The adhesiveness may be such that at least a transfer component of a transfer material described below can be adhered and held. As a preferable example of the resin having such adhesiveness, an ultraviolet curable resin which is cured by irradiation of ultraviolet light can be given. Thermosetting resin containing an organic solvent takes time to solidify and the pattern is easily deformed, but UV curable resin is excellent in quick drying, the degree of shape loss is small, and the thickness of the resin layer is increased. Because you can. However, the thickness of the resin layer (3) is not limited. Further, the degree of adhesion of the resin can be adjusted by adjusting the components, as is well known.

After the formation of the resin layer (3), a transfer material having a transfer component is pressed against the resin layer, and the transfer component (4) (shown in FIG. 3) of the transfer material is applied by utilizing the adhesive force of the resin layer. Resin layer 3
To adhere to the surface.

Here, the transfer material is a so-called hot stamping foil that transfers and transfers the transfer components to a resin layer by detachably attaching and holding the transfer components on the surface of a sheet-like support. The transfer material itself may be transferred to the resin layer, such as a gold foil, but in any case, the transfer material is preferably in the form of a foil or a thin sheet. By using a transfer material in the form of a foil or a thin sheet, the transfer material can be easily deformed along the surface shape of the resin layer (3) when pressed against the resin layer (3). This is because the transfer component can be attached to almost the entire surface.

The transfer component (4) transferred from the transfer material to the resin layer (3) may be colored or colorless. In the case of a color, the color is not limited to a metal color such as gold or silver, and a color other than the metal color may be used depending on the application. Further, the color is not limited to one color, and two or more colors may be mixed, or a part or the whole may shine brilliantly including a light reflection component, or depending on a viewing angle. A mode in which the color changes may be used.

As a method of pressing the transfer material against the surface of the resin layer (3), preferably, as shown in FIG. 4, a long base material (1) on which a large number of resin layers (3) are formed is used. A pair of pressure-contact rollers (6a) and (6b)
A method of performing the treatment while continuously passing the sheets in an overlapped manner. According to this method, mass production can be performed by increasing the efficiency of the transfer operation. In this case, at least the roller (6b) on the transfer material (5) side is formed of an elastic material such as rubber, so that a pressure such that the transfer material (5) is deformed along the surface shape of the resin layer (3) is applied. This is desirable in that the transfer component can be attached to almost the entire surface of the resin layer. Alternatively, as shown in FIG. 5, the transfer may be performed by pressing the transfer material (5) against the base material (1) via a pressure body (9) made of an elastic body or the like. 4 and 5,
(7) is a winding roller for winding the transfer material (5),
(8) is an unwinding roller.

By pressing the transfer material (5) against the surface of the resin layer (3), the transfer component (4) of the transfer material (5) is transferred to the resin layer (3) by the adhesive force of the resin layer (3). Retained
The resin layer (3) is displayed in a predetermined color or the like, and a predetermined display section (10) is formed. On the other hand, since the surface of the base material other than the resin layer (3) has no tackiness, unintended transfer is not performed on this portion.

After performing the transfer in this manner, if necessary,
As shown in FIG. 6, a resin coating layer (11) as a protective layer is formed on the surface of the substrate (1). Resin coating layer (11)
Is a spray method such as screen printing or painting,
As shown in FIG. 6, it may be coated in a thin film form. In addition, as shown in FIG.
May be formed over the entire surface or on the display section (10) to further enhance the three-dimensional display effect or the raised display effect by the lens effect.

When a large number of products are formed by cutting and punching the base material (1) after forming a large number of display portions (10) on one base material (1), screen printing is used. It is efficient to do. According to screen printing,
In addition to the color printing of the substrate (1) and the formation of the resin layer (3), the printing can be performed by one screen printing machine. , Resin application, UV irradiation, transfer with transfer material (5), and formation of coating layer (11) can be made into a line, and the preparation process becomes easy, work can be performed with less personnel, and the production time can be further reduced. And cost reduction can be expected.

[0028]

As described above, according to the present invention, a convex display portion can be formed by a resin layer to which a transfer component is adhered. A decorative member having an effect can be manufactured.

In addition, since the stamping step of the base material for forming the display portion into a convex shape is not necessary, the positioning of the stamping die and the display portion at the time of stamping molding becomes unnecessary, and the production of the stamping die itself is not required. Is also unnecessary. In addition, the substrate may be made of a material that is difficult to form irregularities, and there is no limitation on the material in this respect. Further, since etching and the formation of the concave fitting portion on the back surface of the base material are unnecessary, measures for preventing etching of the display portion and repeated overprinting for forming the deep concave fitting portion are not required.

Further, the resin layer forming the display portion is not easily dented or deformed even when subjected to an external pressure during use as in the case of simply forming the base material into an uneven shape, so that the resin layer is excellent in impact resistance, and has excellent initial impact resistance. Can be maintained for a long time.

Further, by pressing the transfer material against the surface of the resin layer, the transfer component is adhered to the surface of the resin layer by utilizing the adhesive force of the resin layer. The work for displaying is also facilitated, the process can be simplified as compared with the conventional manufacturing method, and the manufacturing time and cost can be reduced. In addition, by appropriately selecting the type of the transfer material, the range of display modes that can be adopted for colors and the like can be expanded.
