Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a decorative body with a decorative pattern such as a cosmetic cap or a container, and a method for manufacturing the same.・Cloisonné decorations are traditionally made of metal as the base material and pressed into the desired shape. After processing, transparent or colored transparent casting 4I
It was obtained by pouring lj[I into the pattern area and solidifying it, and then polishing it to expose the metal pattern area. Press → Leveling → Washing → Casting resin → Drying and solidifying → Surface polishing →
Cleaning → clear paint and finishing → product. Not only are there many steps, but there are various drawbacks such as the long drying time of the A material and Note 1st oil when removing the outer diameter, which reduces product cost and productivity. There was an interlayer in the point of O1! The object of the present invention is to provide a cloisonné-like ornament that can be easily produced with high productivity and a method for manufacturing the same, which has been developed to eliminate the drawbacks of the prior art.

Specifically, the first aspect of the present invention is to coat a transparent or semi-transparent synthetic resin base material with a transparent or semi-transparent metal layer on the surface thereof. This decorative body is characterized by having a bright coating and a patterned or all-over metal layer on the back side.

In addition, the other method is to form a patterned metal layer on the surface of a transparent or translucent synthetic resin base material, coat the entire surface with ultraviolet MKI paint, and then irradiate actinic rays to create an AM A method for producing a decorative body, which comprises curing a material to form a transparent or semi-transparent film, and forming a metal layer on the back side of the synthetic resin base material or on the entire surface of the synthetic resin base material. .

Hereinafter, the present invention will be described in further detail with reference to the accompanying drawings.

FIG. 1 is a plan view showing an example of the decorative body of the present invention, and W
Figure &2 is a cross-sectional view taken along the line 'G'. An OA patterned metal layer 1 such as patterns and letters is formed on a synthetic resin base material 11.
2 is provided, and $13 is provided above it. On the other hand, a metal layer 14 is formed entirely on the back surface. When this decorative body is viewed from above, the metal layers 12 and 14 look like metal base materials, and the synthetic resin base material 11 looks like glass glaze, and the surface is also heated with a coating 13. It works and looks like cloisonné. *5a11 is a cosmetic product incorporating this decorative body.It is made of acrylic resin such as styrene styrene-limeter methacrylate, llicarbonate resin, etc., and is transparent or translucent. That is, −
The texture of the decorative body can be adjusted by adding a coloring material VJILK to make it colored and transparent. Used.

The coating 1lls is made of a transparent or translucent substance capable of forming a test material, such as a synthetic resin, and is generally transparent. The coating 13 is preferably made of a resin with high surface hardness, excellent gloss, and good durability. From this point of view, ultraviolet curing resin is preferable. ! As a chemical resin,
Examples include acrylic resin, unsaturated polyester, epoxy or urethane-modified acrylic resin, etc. The metal layer 14 may also be formed in the same manner as the metal layer 12. In addition, in FIG. 2, the metal layer 14 is provided on the entire back surface, but
This is not necessarily necessary; for example, the metal layer may not be provided in areas that are not visible from the top side.Next, the method for manufacturing the decorative body of the present invention will be described.

A synthetic srj formed into the external shape of a decorative body by injection molding method etc. A base material 11 is obtained (FIG. 4).

Next, the surface 154C of the base material 11, ? A turf-shaped fC metal layer 12 is formed (FIG. 85).

Next, a transparent ultraviolet S curing material is applied on the metal layer 12 and the base material surface 15, and is solidified by irradiation with ultraviolet rays (actinic rays) to form a #13 (FIG. 6).

Next, a metal layer 14 is formed on the entire surface of the back side of the base material (FIG. 812). This step may be performed prior to the film forming step or the metal layer 12 forming step.

According to the decorative object of the present invention, when viewed from the surface side, the metal layer looks like a metal base material, and the synthetic resin base material looks like a glass glaze, giving an excellent cloisonné-like texture. . In addition, the UV coating has a good gloss and is durable! If it is formed using Type II resin, the cloisonné-like texture will be further improved, and the surface will be hard and scratch-resistant, allowing it to maintain its function as a decorative object for a long period of time. ,
The process can be considerably shortened compared to the conventional method, and since the base material is synthetic resin, it is cheaper than metal, and the injection molding method does not waste any base material, making it easier to mold than the conventional method. It can be manufactured with low manufacturing costs and high productivity.

Example 1 Red transparent 7/J'l5ll formed by injection molding method
As resin (Asahi Dow; Taitsur 767) base.

On one side of the material (size Is-φ, thickness o, 7wm), a silicone 2-piece O symbol formed in a floral pattern and a gold color 1'& (made by Murata gold leaf; 246 gold color w1) were used. A metal layer with a floral pattern was obtained by heat transfer. In addition, on the other side of the base material, a 79 side transfer foil (made by Murata Kinpaku: :I/l'
A metal layer was obtained by heating the entire surface of the 9-side gold foil (for Meme/As resin).

Furthermore, UV II curing paint (manufactured by Mitsubishi Rayon; Diabeam UL-1oxo
) After spray coating, a transparent film was formed by irradiating it with a 2KW high-pressure mercury lamp for 5 seconds, and a decorative body resembling cloisonné was obtained, with the metal base being gold and the glass glaze being transparent mauve. Example 2 Blue transparent polymethyl methacrylate resin (manufactured by Mitsubishi Rayon, Acrivet) base material formed by injection molding method (
Size 15 φ, thickness 0.7 haze) piece EIK, floral pattern with screen ink (manufactured by Toyo Ink; sa 5ooo)
A metal layer with a floral pattern was obtained by starlin printing using gold color). Then, a transparent film was formed on this surface in the same manner as in Example 1.Furthermore, the other surface of the base material was coated with a vacuum [
When a metal layer was formed on the entire surface by vapor-depositing aluminum at 11 x 10' Torr, a decorative body resembling cloisonné was created, with the metal base being silver, the embossed floral pattern being a matte silver, and the glass glaze being blue and transparent. Prayed @
