Next, a glass plate 6 is placed on the upper surface of the base film 5, and a group of ultraviolet lamps 7 are arranged with the upper and lower glass plates 6 and 1 sandwiched therebetween.
Bake pattern 8.

Therefore, the transparent portion from which the light-shielding surface layer R has been peeled off and the ultraviolet curable resin 4 between the portion and the base film 5 are cured (FIG. 4).

The uncured resin 4 is washed off with a washout solution 9 such as a solution containing a surfactant and the like.
The protruding groove pattern 8a is exposed on the lower surface (Fig. 5).

The remaining UV-curable resin 4 is again irradiated with UV rays and after-cured to obtain a sandblasting masking film M having groove patterns 8a exposed on the base film 5 (57) (FIG. 6).

The above is the manufacturing method of the template M which can be applied to the mass production of a small number of kinds.
For example, an elastic body for sandblasting obtained by sticking a film such as release paper on both sides is cut out together with the film on one side, and a masking film M for sandblasting having a groove pattern 8a that reaches the film on the other side is created. The flame-retardant paper can be used as the base film 5.

Next, the production of an inlaid pattern product using the above sandblasting masking film M will be described with reference to the flow chart of FIG. 2 and the schematic views of the production situation shown in FIGS. 7 to 13.

The release sheet 10 is releasably adhered to the surface of the groove pattern 8a of the sandblasting masking film M prepared as described above by using a desired adhesive (adhesive) (58) (FIG. 7).

On the other hand, a decorative plate D made of a thin natural stone plate on the surface of a transparent plate T made of a glass plate having a predetermined thickness.
The back surface of is adhered and integrated (FIG. 8).

In recent years, due to the progress of stone cutting technology,
It became possible to slice natural stones to a very thin thickness (for example, 3mm thick) to create natural stone plates.
In the method for manufacturing a product with an inlaid pattern according to the present invention, the decorative plate D for adhering the thin natural stone plate to the surface of the transparent plate T is used.
Can be suitably used as.

As the transparent plate T, a transparent or translucent glass plate or a synthetic resin such as a transparent or translucent acrylic resin can be used.

As the decorative plate D, from the viewpoint of giving a high-grade feeling, it is preferable to use a plate made of ebony or rosewood, an artificial marble plate made of unsaturated polyester resin or ceramic powder, etc. in addition to the natural stone plate described above. However, it is also possible to use a plate made of other high-grade material.

Next, the release sheet 10 is peeled from the sandblast masking film M, and the film M is adhered to the surface of the decorative plate D on which the inlaid pattern 8c to be described later is to be formed (59) (FIG. 9).

In the bonding step, the decorative plate D
The surface of the is usually a finished surface, and a release film 12 is preliminarily adhered to the same surface in a peelable manner (5
8a) (Fig. 8). Therefore, the sandblasting masking film M is adhered to the surface of the decorative plate D via the release film 12 (FIG. 8).

Next, the surface of the decorative plate D is sandblasted with hard particles P such as zirconia (60).
(Figure 9).

That is, the base film 5 and the release film 12 of the sandblasting masking film M are broken, the hard particles P are made to collide with the surface of the decorative plate D through the groove pattern 8a, and the groove pattern having a shape corresponding to the groove pattern 8a. 8b can be formed on the surface of the transparent plate T (FIG. 9) (FIG. 10).

Then, the sandblasting masking film M is peeled off from the decorative plate 11 (61), and the groove pattern 8b is formed.
The inside is filled with the translucent decorative material 13 (62) (Fig. 11).

After that, when the translucent decorative material 13 is not yet cured, the surplus translucent decorative material 13 on the surface of the decorative plate D is removed by a scraping jig 14 such as a squeegee.
Scrap off (63) (Figure 11) (Figure 12).

After the translucent decorative material 13 is sufficiently cured and cured (64), the release film 12 is removed from the decorative plate D to produce the inlaid pattern product B.
(65) (66) (Fig. 13) (Fig. 14).

As is apparent from FIG. 14, in the present invention, the light source L such as a lamp is arranged on the back side of the inlaid pattern product B, and the light emitted from the light source L is transmitted to the transparent plate T and the translucency. The decorative material 13 can be penetrated to the surface side to obtain the light decoration effect on the surface side.

Therefore, by arranging the light source L in a position close to the translucent decorative material 13, it is possible to intensively irradiate the translucent decorative material 13 with a strong light beam, and a sufficient light decoration is achieved. The effect can be raised.

Further, since the light source L and the transformer can be housed on the back side of the inlaid pattern product B, a space can be freely used on the front side of the inlaid pattern product B,
A neat interior design is possible.

Further, not only the decorative plate D but also the transparent plate T
By also sandblasting the surface layer portion, unevenness is formed on the surface layer portion, and the adhesion performance between the transparent decorative material 13 to be inlaid and the transparent plate T can be improved.

From the aspect of the manufacturing process, the surface of the decorative plate D on which the groove pattern 8b is not formed is protected by the peeling film 12 in the scraping process.
Although the scraping jig 14 and the scraped-out translucent decorative material 13 itself may damage the surface of the release film 12, the surface of the decorative plate D under the release film 12 is reliably prevented from being damaged. can do.

Particularly, the hard particles P such as zirconia used for sandblasting are used for the decorative plate D after the sandblasting step.
Even when it remains on the surface of the plate, the release film 12 described above can surely prevent the surface of the decorative plate D from being scratched.

Further, even if the decorative plate D is a material such as natural stone or wood in which hard parts and soft parts are mixed and partially porous, by using the release film 12, Decorative material in scraping process 13
Can be reliably prevented from entering the inside of the substrate 11.

Therefore, a good quality inlaid product B can be mass-produced at low cost.

Further, the present invention is also characterized in that as the translucent decorative material 13, an unsaturated polyester resin or an epoxy resin containing an ultraviolet light emitting substance is used.

The ultraviolet light-emitting substance contained in the light-transmitting decorative material 13 is vividly colored by irradiating with ultraviolet light of a specific wavelength.

Further, some concrete examples of the component constitution of the translucent decorative material 13 are as follows.

[Component structure 1] Unsaturated polyester resin 40.00% Curing accelerator 1.00% UV light-emitting substance 48.00% (Although bismuth activator is added to the matrix of calcium fluorosilicate) Filler 9.00% Pigment 2.00% [ Ingredient composition 2) Unsaturated polyester resin 26.25% Ultraviolet light emitting substance 50.00% (even if bismuth activator is added to the matrix of calcium fluorosilicate) Extender material 15.00% (glass powder of several μm) Pigment 2.00% Low shrinkage Agent 8.75% However, the ultraviolet light emitting substance is not limited to those of the above components, for example, manganese, arsenic activated zinc silicate green light emitting phosphor, manganese activated magnesium silicate red light emitting phosphor, A manganese-activated zinc magnesium orthophosphate red light emitting phosphor or the like can be used.

Further, as the translucent decorative material 13, an ultraviolet curable resin may be used instead of the unsaturated polyester resin as shown below.

[Component composition 3] UV-curable resin 100 parts by weight Ultraviolet light-emitting substance 10 to 30 parts by weight (even if bismuth activator is added to matrix of calcium fluorosilicate) Filler (glass powder of several μm) 5 to 20 parts by weight When an unsaturated polyester resin is used as the main component of the translucent decorative material 13, it is difficult to set the curing time by adjusting the mixing amount of the curing accelerator, and therefore defoaming is not possible. If the time cannot be taken sufficiently, or if the amount is too small or too large, it is uneconomical if it is too large, and if it is too small, defective products may occur.

On the other hand, when an ultraviolet curable resin is used as the main component of the light-transmitting decorative material 13, it does not cure unless it is irradiated with ultraviolet rays, so that the curing time can be easily set and the amount can be set. Since it can be prevented from being excessively small or excessive, it is economical and can prevent defective products from being generated.

The light-transmitting decorative material 13 is preferably a UV-curable resin mixed with a UV light-emitting agent, but a light-transmitting synthetic resin containing a usual pigment or a predetermined amount of a fluorescent pigment can also be used. ..

Further, FIGS. 15 to 18 show the manufacturing process of the multi-colored inlaid product B.

First, in the above-described manner, as shown in FIGS. 15 and 16, the translucent decorative material 13a is provided in the groove pattern 8d provided on the surface of the transparent plate T through the decorative plate 11. Fill and cure.

After the pigment is filled and cured, the peeling film 12 is once peeled off and a new intact peeling film 12 is attached.

Next, as shown in FIGS. 17 and 18, a transparent plate
A translucent decorative material having a color different from that of the translucent decorative material 13a described above in a groove pattern 8e provided on the surface of 13
Fill and cure 13b.

After the pigment is filled and cured, the release film 12 is once peeled off, and a new intact release film 12 is attached again.

Further, as shown in FIGS. 19 and 20, a translucent decorative material having a color different from that of the translucent decorative material 13a described above in the groove pattern 8f provided on the surface of the decorative plate 11. Fill and cure 13c.

After that, the final release film 12 is released from the surface of the decorative plate D, and the inlaid pattern product B having a multicolor pattern can be manufactured.

Further, in the manufacturing process, each peeling film 12 can surely prevent the surface of the substrate 11 from being scratched when the scraping work is performed by the scraping jig 14, and at the same time, It is possible to reliably prevent the light decorative materials 13c from mixing with each other, and a clear multicolor inlaid pattern can appear on the product B with the inlaid pattern.
