Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a decorative structure such as a compact having a border pattern rich in glitter.

[Conventional technology]

Generally, as a decorative body having an end face rich in glitter,
There is a sheet-like material in which transparent resin contains fluorescent dye pigments. This type of sheet-like material has the function of absorbing ultraviolet rays in the invisible region through the action of the above-mentioned fluorescent dyes and pigments, converting them into visible light, and emitting the visible light. Since light is added and radiated from the end face, the end face appears to shine. Further, from this end surface, the effect of the fluorescent dye pigment contained in the length direction of the sheet-like body is strongly expressed, and the end surface appears darker and brighter than other parts. The sheet-like material having such characteristics has a special aesthetic appearance because its end surfaces appear to shine and are darker than other parts due to the action of the ultraviolet-converted visible light and the concentration of fluorescent dye and pigment. It is used for miscellaneous goods, toys (for example, name tags and nameplates), etc. However, such a sheet-like object is a flat plate-like object, and even if the end surface looks bright and dark, it is not possible to see the entire surrounding end surface at the same time.
When the end face is facing downward, the end face cannot be seen.

[Problem that the invention seeks to solve]

As mentioned above, sheet-like decorations containing fluorescent dye pigments have the above-mentioned restrictions on their aesthetic appearance, so their use is limited to miscellaneous goods, toys, etc. as described in +'+if. The reality is that it has not yet been used for other purposes, and it is desired to expand its range of applications.

This invention was made in view of the above circumstances, and it applies decorative bodies containing fluorescent colorants such as the above-mentioned fluorescent dyes and pigments to a wide range of uses such as cosmetic compacts, caps, and accessories. The purpose is to provide a border pattern that is rich in gender.

[Means for solving problems]

In order to achieve the above object, the decorative structure of the present invention includes:
A transparent resin molded body containing a fluorescent colorant and a molded body having a reflective surface, wherein the end face of the transparent resin molded body and the reflective surface of the molded body having the reflective surface are arranged at a predetermined interval at least in part. The structure is such that they face each other while maintaining the same.

Next, this invention will be explained in detail.

FIG. 1 provides a detailed explanation of the invention. In the figure,
1 is a transparent sheet-like molded product containing a fluorescent colorant, and is made of a transparent resin. Reference numeral 2 denotes a reflective surface-equipped molded body made of synthetic resin and having a reflective surface 3 . Light incident from one end face of the transparent sheet-like molded body 1 containing a fluorescent colorant travels linearly inside and is emitted from the other end face la in the direction of the arrow, and is emitted from the reflective surface-equipped molded body 2. upward reflective surface 3
The light is reflected by the light, travels upward, and is identified by the naked eye 4. On the other hand, a part of the light that enters the interior from the surface of the transparent sheet-like molded body 1 containing fluorescent colorant undergoes total reflection inside the sheet-like molded body 1, and is emitted from the other end surface 1a as shown by arrow B. The light is reflected by the reflective surface 3 of the reflective surface-equipped molded body 2 and is recognized by the naked eye 4 similarly to the refracted light A. In this case, the inclination of the upward reflecting surface 3 is determined by the larger of the two angles θ and θ' between the center line of the transparent sheet-like molded body 1 and the reflecting surface, as shown in FIG. The angle θ of is an obtuse angle, especially 1
A setting in the range of 00° to 150° provides good results. In the transparent sheet-like molded article 1 containing a fluorescent colorant, as described above, the fluorescent colorant converts the ultraviolet rays in the invisible part of the incident light into visible light, which is converted into visible light. In addition to this, the effect of the fluorescent colorant emitted from the other end surface 1a and distributed in the length direction from the end surface 1a is strongly expressed, and therefore the end surface la is darker in color than the other parts, and It appears to shine like a dot, and that is the reflective surface 3 of the reflective surface-equipped molded body 2.
reflected in Therefore, even if the other end surface 1a is facing downward as in the sheet-like molded body l and the end surface la is not directly visible to the naked eye, the brightness and dark color of the end surface are the same as the reflective surface. 3, and the entire outer peripheral end surface of the sheet-like molded body 1 can be seen at the same time. As a result, a dark colored band appears on the outer periphery of the sheet-like molded body 1, and a beautiful border pattern is formed.

As a result, the present invention extends the scope of application of the above-mentioned fluorescent coloring-containing decorations not only to flat plate-like items such as name tags and nameplates, but also to caps, compacts, toys, accessories, etc. It was possible to expand it to something with a three-dimensional shape.

The transparent resin molded article containing fluorescent colorant used in this invention includes dry type, thermosetting, thermoplastic transparent resin (including not only completely transparent but also translucent), fluorescent dye, fluorescent pigment, etc. It can be manufactured by blending a fluorescent coloring agent and performing sheet-form coating and drying, casting hardening, lamb molding, etc. Examples of the dry transparent resin include nitrocellulose (also known as collodion liquid) and polyvinyl alcohol, and examples of the thermosetting transparent resin include unsaturated polyester resin, diethylene glycol bisallyl carbonate, acrylic ultraviolet curable resin, etc. It will be done. Examples of thermosetting transparent resins include single or copolymers of polycarbonate polymethacrylate, transparent ABS resin, polyvinyl chloride, polyvinyl acetate, and polyacrylnidonyl; Polymers (ethylene-vinyl acetate, ethylene-ethyl acrylate, ethylene-acrylic copolymers, propylene-ethylene copolymers) can also be used.

Among these, polycarbonate 1-
．． Polymethacrylate, polyvinyl acetate, ethylene copolymers, etc. are suitable, and resins containing acid components (terephthalic acid, acrylic acid) are preferably used from the viewpoint of bonding with fluorescent pigments and improving durability. More suitable.

As the above-mentioned fluorescent colorants such as fluorescent pigments and fluorescent dyes, known ones sold by Ciba Geigy, IC1, Mitsui Chemicals, etc. can be used. In the transparent resin molded article containing the fluorescent colorant as described above, the concentration of the fluorescent colorant is set to 3% by weight (hereinafter abbreviated as 1%) or less. More preferred is O, OO5 to about 0.3%.

Setting within this range will give the most favorable results.

The molded body with a reflective surface that faces the fluorescent colored diagonally filled transparent resin molded body may be formed by pasting metal foil such as aluminum foil or copper foil on the end face of a widely used well-known resin, or
It is possible to use a material whose five sides are coated with metal foil, coated with a paint containing metal foil powder, or coated with a silver nitrate solution. In this case, the reflective surface
When the thickness of the metal film forming the metal film is set within the range of 0.01 to 50 μm, good results can be obtained in forming the border pattern. Note that the entire molded body with a reflective surface may be made of metal.
