It relates to medallions and other decorative bodies and their manufacturing methods, and more specifically, in order to display multiple different colored parts on the decorative body, transparent materials are used as the base material of the decorative body so that the colors applied to the back side can be seen through the surface. (Including cases where the pattern or color on the back side is translucent to the extent that it can be seen through the front surface) A method for producing a multicolored pattern on a decorative body using materials and a decorative body having a pattern expressed by the method Related.

Medallions, brooches, and other decorative objects have a normal thickness and have a free planar shape such as a circle, oval, diamond, polygon, or flower shape, but they also have a pattern formed by different colored parts. By having
It is required to enhance its decorativeness. and,
The boundaries of different colored parts are often required to be demarcated by clear parting lines and to have a pattern with a clean outline.

The object of the present invention is to manufacture and provide a decorative body having a pattern that meets such requirements by simple means.

The base of the decorative body of the present invention is made of a colorless or colored transparent (including the above-mentioned translucent) material, that is, glass or a synthetic resin material such as polycarbonate resin, acrylic resin, or the like.

The shape of the decoration may have the above-mentioned normal thickness and planar shape, but the back side thereof has a convex part whose back surface is almost flat, and a concave part that is recessed from the surface of the convex part according to a predetermined pattern. One feature is that there is a clear ridge line between the back surface of the convex part and the concave part.

The decorative body manufacturing method of the present invention includes a molding step of molding a substrate made of a transparent material having a concave portion (or a plurality of concave portions) surrounded by a circumferential side defined by a distinct ridge line on the back surface of the convex portion. and a hot stamping step in which a first tone layer consisting of a desired color or a combination of colors and patterns is transferred onto the back side of the convex portion using a hot press, and the first tone layer is applied over almost the entire back side of the substrate that has undergone the above hot stamping step. An entire surface process of applying a second color tone layer different from the above is added as necessary. It consists of a coating process in which a protective coating is applied to the entire back side of the substrate, and if necessary, a translucent mirror-like second color layer is formed by the above-mentioned entire surface process, and a pattern of a third color layer is formed on the back side of the second color layer. including administering.

According to the above method, clear separation lines are formed between different color tones, and a beautiful decorative body with a clear color pattern is provided.

The present invention will be explained below based on the accompanying drawings.

1 and 2 show an example of a decorative body made by the method of the present invention. The overall shape of the decorative body is a circular plate-like body, and the base body 1 is transparent (with a pattern on the back side The surface is made of a synthetic resin material (including semi-transparent to the extent that the color and color can be seen through the surface), and the surface may be provided with a three-dimensional pattern with appropriate raised or recessed parts if necessary, but the one shown in the figure is a flat surface.

FIG. 2 is a cross-sectional view showing the base 1 with its back side facing upward. On the back side of the base, there is a first recess 2a recessed in an annular shape from the back surface and a second rectangular recess 2b.
is formed. Although the inner surface of the illustrated recessed portion is smooth, irregularities may be provided as appropriate to create a three-dimensional pattern on the surface. On the back side of the base, a first color tone layer 3 (for example, a dark blue layer) is formed by hot stamping on the rear surface 11 which is a convex portion, and when viewed from the surface of the decoration, the base tone (30 other colors) appears to be dark blue.

In this example, a second color tone layer 4 (silver glitter layer) formed by metal vapor deposition is provided on the entire back side of the substrate on which the first color tone layer 3 is provided, and if necessary, the outer surface of the second color tone layer 4 is The whole is covered with a protective coating layer 5. In this example, the metal evaporated layer is a semi-transparent mirror-like film that can partially transmit light (it becomes a semi-transparent mirror if the layer thickness is approximately 100 A° or less, but preferably 50 A° or less). is formed,
A third tone layer 6 is provided on the back side of the second tone layer 4 in the second recess 2b, and a protective coating layer 5 is provided.
covers that part as well.

The protective coating layer 5 has a second color tone layer 4.
is a metal vacuum-deposited layer, and it is applied when its weather resistance and moisture resistance are insufficient and there is a risk of discoloration, or the adhesion strength to the substrate 1 is insufficient and the color tone layer 4 may peel off. This protective coating layer 5 may be omitted if the second tone layer 4 is a top coat layer and is a paint tone layer of a different color from the first tone layer 3 by ordinary spray coating.

When this decorative body is viewed from the front side, as shown in FIG. Silver bright parts 40a, 40b
appears, and the unique color pattern 60 formed by the third tone layer 6 can be seen through the square bright portion 40b, giving the appearance of a decorative body with an extremely beautiful multicolor pattern. However, the third tone layer 6 may not be applied.

The decorative body as described above was made by the method of the present invention described below.

In the method of the present invention, first, a base of a decorative body having a surface shape of a desired external shape is recessed in a predetermined shape into a part of a convex part 11 (FIG. 3) having a flat back surface. The process begins with molding the base body 1 having the following characteristics. Such molding can be easily carried out by known injection molding if the material is a synthetic resin material, or by using a mold if the material is glass.

In this molding, the entire back surface of the convex portion 11 on the back side of the base 1 is made into a flat surface that is substantially in the same plane. However, it is also permissible to partially form a slightly curved surface portion 12 as shown in FIG. 3B, as long as it does not interfere with the application of color tones by hot stamping, which will be described later. As shown in the enlarged view of FIGS. 3a and 3b, the recessed part 2 (common to 2a and 2b) provided on the back side of the base has an obtuse angle that is slightly inclined when perpendicular to the back surface of the convex part 11. Regardless of whether the convex part 11 is a back surface or a part thereof, the convex part 11 is surrounded by a circumferential side surface 22 defined by a ridge line 21 forming a sharp corner between the convex part 11 and the curved surface part 12 forming a part thereof. The recessed part 2' in Fig. 3c is the peripheral side 2'.
There is no ridge line between 2' and the back surface of the convex portion 11. Such a shape is not suitable for implementing the present invention.

FIG. 4 shows a first color tone layer 3 on the convex portion 11 of the base.
The base body 1 is fixed with an appropriate jig 8 with its back side facing upward.
A plurality of base bodies may be fixed in parallel. Above the back side of the substrate 1, a film 7 for a known hot stamp is supplied from one supply roll 71 and wound around the other take-up roll 72 and sequentially supplied thereto. As is well known, the hot stamp film 7 carries a colored layer or foil for hot stamping on its surface that is pressed against the workpiece. After fixing the base body, when the hot plate 73 is pressed against the back side of the convex portion 11 on the base body 1 from the back side of the film 7 with a predetermined pressing force and the film is moved, the back side of the convex portion of the base body 1 is covered with a number of spots on the entire surface. One tone layer 3 is formed. If the pressing surface of the hot plate is made elastic, it is also possible to stamp the curved surface portion 12. When the film 7 is peeled off, burrs 3' as shown in FIG. 6 may remain on the periphery of the stamp layer, but these can be easily removed using a vacuum suction device or brushing.

If a large number of substrates are sequentially hot-stamped in the same manner, all substrates will have a uniform first color layer 3.
is formed.

The substrate that has undergone the hot stamping process is then fitted into a mask 9 with its back side open as the top surface, and is coated with a first color tone layer 3 formed by hot stamping by a known coating method such as vacuum vapor deposition of metal or spray painting in different colors. A second color tone layer 4 is formed on the entire back side.
(full-scale process).

The mask 9 is easily manufactured by vacuum forming a synthetic resin sheet with a thickness of about 1 mm into a shape having a peripheral wall 91 having an inner diameter that is the same as or slightly smaller than the surface shape of the base. As shown in FIG. 5, the substrate 1 is fitted into this and the mask and the substrate are loaded into a vacuum deposition apparatus or coated. When the second color tone layer 4 is a vacuum-deposited layer, metals used include chromium, aluminum,
Antimony, copper or alloys thereof can be used.
Vacuum deposition includes all known means such as resistance heating or sputtering.

When the second tone layer is the translucent mirror-like film,
If necessary, a third color tone layer 6 consisting of a different color tone or multicolored pattern is further provided on a part of the back side of the recessed portion. This layer can be easily formed by transferring a pattern layer using a known transfer paper.

On the outer surface of the second color tone layer (including the third color layer 6) 4, if necessary, a protective coating layer 5 made of a highly durable coating material such as a synthetic resin material is formed to cover the entire surface. (Coating process).

When the decorative body completed with the protective coating layer 5 is taken out from the mask 9, when the decorative body is viewed from the front side of the base body, the boundary between the aforementioned dark blue ground color portion 30 and the silver glittering portions 40a and 40b is visible. but,
Since the divisions formed by the ridge lines 21 represent extremely clear parting lines, a clear three-dimensional pattern is created, which has the effect of enhancing the aesthetic sense of the decorative body. If a pattern of a different color is displayed through a semi-transparent mirror film, the decorative effects will be even more diverse.

As for the manufacturing method, the main body of the necessary color tone layer is formed only by hot stamping on the convex parts and vacuum deposition or painting on the entire processed surface, and different colored parts are formed by conventional partial masking. This method has the effect that it does not take much time to do the masking, and it does not cause any inconveniences such as blurred patterns in the surrounding area due to masking.
