Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glittering decorative body useful for a display or the like.

[0002]

2. Description of the Related Art Pearl pigments are generally obtained by coating a ground material of natural mica or quartz with a metal oxide such as titanium dioxide or iron oxide, or a ground material of quartz. Is colored with a colored pigment, and is widely used in paints for automobiles and household electric appliances, cosmetics, packaging materials, toys and the like.

[0003] Such pearl pigments can be used for a long period of time because they have good weather resistance and the particles themselves are unlikely to change over time. No reflected light was obtained, and strong reflected light was not obtained.

In recent years, pearl pigments having a particle diameter of about 40 μm that emit strong reflected light have been manufactured due to a dramatic improvement in the crushing technology of quartz and a coating technology of titanium dioxide and the like. Further, pearl pigments emitting reflected light of two or more colors are also manufactured. However, these pearl pigments are very expensive due to the complexity of the production method and the difficulty of quality control, and are not practical to use for decorative objects.

On the other hand, there are metal flakes and plastic flakes on which metal is deposited (so-called lame) as those exhibiting strong reflected light (brightness). In such flakes, if the flake diameter is several tens of microns, the brilliant feeling is insufficient. Therefore, the flake diameter is preferably 200 μm or more.

[0006] However, when printing an ink containing flakes by a screen printing method, in order for the flakes to pass through the screen plate, an opening having a size about four times the flake diameter is required on the screen plate.
For example, when printing an ink containing flakes having a flake diameter of 200 μm, a coarse screen plate of 20 to 30 mesh is required. When such a coarse screen plate is used, a large amount of an emulsion or the like is required, and the amount of ink used is 7 to 8 times that when a screen plate of 150 mesh is used, and the printing time is also increased. Because of the length, the production cost of the product becomes extremely high.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a glittering decorative body capable of obtaining high glitter at low cost and a method of manufacturing the same.

[0008]

In order to achieve the above object, a first glittering decorative body according to the present invention comprises a plate-like or sheet-like transparent substrate and a transparent substrate. A plurality of dot-shaped convex lenses formed at predetermined intervals, and a glitter layer containing glitter particles formed on the back surface of the transparent base material are provided (claim 1).

[0009] In the glittering decorative body (Claim 1),
Light incident from the front surface side of the transparent substrate is reflected on the glitter particles in the glitter layer formed on the back surface of the transparent substrate and appears on the front surface side of the transparent substrate. At this time, due to the action of the dot-shaped convex lens formed on the surface of the transparent base material, the reflected light appearing on the surface side of the transparent base material is enlarged and looks like a large and strong light. Since a plurality of enlarged reflected lights appear at random in accordance with a change in the viewing angle, high glitter and beauty can be obtained.

As the glitter particles, ordinary inexpensive particles can be used, and the glitter layer can be formed on a transparent substrate at low cost.
It can be manufactured at low cost. However, the present invention
A glittering decorative body that cannot be manufactured at low cost is not excluded from the technical scope of the invention.

A second glittering decorative body according to the present invention comprises: a plate-shaped or sheet-shaped transparent substrate; a plurality of dot-shaped convex lenses formed on the surface of the transparent substrate at predetermined intervals; A glittering material having a layer containing glittering particles attached to the back surface of the transparent substrate (claim 2). The “brilliant material” may be composed of only the layer containing the glittering particles, and may not be in a layered form.

[0012] In the glittering decorative body (Claim 2),
Light incident from the front surface side of the transparent substrate is reflected by the glitter particles of the glitter material attached to the back surface of the transparent substrate and appears on the front surface side of the transparent substrate. At this time, due to the action of the dot-shaped convex lens formed on the surface of the transparent base material, the reflected light appearing on the surface side of the transparent base material is enlarged and looks like a large and strong light. Since a plurality of enlarged reflected lights appear at random in accordance with a change in the viewing angle, high glitter and beauty can be obtained.

As the glitter particles, ordinary inexpensive particles can be used, and the glitter layer can be formed on the glitter material at low cost. Therefore, the glitter decoration is manufactured at low cost. be able to. However, the present invention does not exclude a glittering decorative body that cannot be manufactured at low cost from the technical scope of the present invention.

In the above-described glittering decorative body (claim 2), the glittering layer is provided on the glittering material side and is separate from the transparent substrate, but the material and shape of the glittering material are different from those of the transparent substrate. The method is not limited to the above and is various, so that the method of forming the layer containing the glittering particles is also various. That is, in the glittering decorative body (Claim 2), it is also possible to form a glittering layer having a pattern or the like that cannot be directly formed on the transparent substrate.

In the glittering decorative body (Claim 2), even if another decorative sheet is partially (eg, near the center) between the transparent base material and the glittering material. Good (claim 3). The “decorative sheet” also includes the concept of a film.

According to the glittering decorative body (claim 3),
Since a decorative sheet having a desired pattern, color, or the like can be displayed together with a plurality of large and strong reflected lights, the decorative sheet can be strongly appealed to a viewer.

Further, the glittering decorative body (claims 2 and 3)
In the above, the transparent base material and the glittering material may be attached and peelable (claim 4). According to the glittering decorative body (claim 4), it is possible to reuse the glittering material and / or the transparent substrate, and to replace the decoration sheet interposed between the transparent base material and the glittering material.

In the glittering decorative body (claims 1 to 4), the diameter of the dot-shaped convex lens is 0.25 to 1 mm.
And the height of the dot-shaped convex lens is 40 to 100.
μm, and the interval between the dot-shaped convex lenses is 0.17.
5 to 0.9 mm, and the particle size of the glittering particles is 5 to 1 mm.
Preferably, the thickness of the transparent substrate is 1 to 5 mm (claim 5). When the diameter, height and interval of the dot-shaped convex lens, the particle size of the glittering particles, and the thickness of the transparent base material are within the above ranges, the dot-shaped convex lens efficiently expands the reflected light of the glittering particles. At the same time, the plurality of enlarged reflected lights move on the plurality of dot-shaped convex lenses according to the change in the viewing angle.

In the first method of manufacturing a glittering decorative body according to the present invention, a plurality of dot-like convex lenses are formed on a surface of a transparent substrate by printing at predetermined intervals, and the back surface of the transparent substrate is formed. A coating containing glittering particles is applied to the surface of the transparent substrate (claim 6). Forming a dot-shaped convex lens by printing, and applying a glitter material obtained by applying a coating material containing glitter particles to the surface of the base material, and affixing the glitter material to the back surface of the transparent base material. Item 7). Note that “paint” also includes the concept of ink, and “application” includes the concept of printing.

[0020] The method for producing the glittering decorative body (Claim 6)
When the dot-shaped convex lens is formed by printing as in 7), the dot-shaped convex lens can be formed accurately at low cost.

[0021] A method for producing the glittering decorative body (Claim 7)
In the above, another decorative sheet may be partially interposed between the transparent base material and the glittering material (claim 8).

[0022] The method for producing the glittering decorative body (Claims 6 to 6)
In 8), it is preferable that the dot-shaped convex lens is formed of a photocurable resin. If the material of the dot-shaped convex lens is a photocurable resin,
After printing the photocurable resin in the form of dots (at this stage, the photocurable resin is convex due to surface tension),
Because the photocurable resin can be cured by irradiating light before the dot-shaped photocurable resin is crushed,
A dot-shaped convex lens having a good shape can be formed.

[0023] A method for producing the glittering decorative body (Claims 6 to 6)
In 9), the dot-shaped convex lens is preferably formed by screen printing (claim 10). According to screen printing, when the ink is printed in the form of dots on the surface of a transparent substrate through a screen plate, and the screen plate is separated from the transparent substrate, the printed dot-shaped ink is printed on the screen plate. Therefore, the dot-shaped ink becomes a convex lens with a height, and can be a dot-shaped convex lens having a good shape.

[0024]

Embodiments of the present invention will be described below. [First Embodiment] FIG. 1 is a schematic perspective view of a glittering decorative body according to a first embodiment of the present invention, and FIG. 2 is a schematic sectional view of the glittering decorative body according to the embodiment.

As shown in FIGS. 1 and 2, the glittering decorative body 1 according to the first embodiment comprises a transparent substrate 2 and a plurality of dot-shaped convex lenses 3 formed on the surface of the transparent substrate 2.
And a glitter layer 4 containing glitter particles formed on the back surface of the transparent substrate 2.

The transparent substrate 2 has at least such transparency that light incident from the front side is reflected by the glitter layer 4 (brilliance particles) on the back side and appears on the front side.
It may be colored. Such a transparent substrate 2 is made of, for example, acrylic resin, vinyl chloride, polycarbonate,
It is made of a plastic plate or a plastic sheet made of polyethylene, polypropylene, polyethylene terephthalate or the like, or a glass plate, and the degree of rigidity is not particularly limited according to the intended use as a decorative body.

The thickness t of the transparent substrate 2 depends on the size and shape of the convex lens 3 and the intended use as a decorative body, but is preferably 1 to 5 mm, particularly preferably 2 to 3 mm.
It is preferred that When the thickness t of the transparent substrate 2 is less than 1 mm or more than 5 mm, it is difficult to obtain a desired glitter.

The dot-shaped convex lens 3 has a function of making light reflected by the glittering particles of the glittering layer 4 appear enlarged. Therefore, how the relationship between the diameter and height of the dot-shaped convex lens 3 and the thickness of the transparent substrate 2 should be determined depends on the focal length of the dot-shaped convex lens 3.

Although it depends on the particle size of the glittering particles contained in the glittering layer 4 and the thickness t of the transparent substrate 2, the diameter d of the dot-shaped convex lens 3 should be 0. 25-
It is preferably 1 mm, particularly 0.5 to 0.85 mm
The height h of the dot-shaped convex lens 3 is preferably 40 to 100 μm, and more preferably 60 to 80 μm.
μm, and the interval p between the dot-shaped convex lenses 3 is preferably 0.175 to 0.9 mm, and particularly preferably 0.35 to 0.5 mm.

Although the dot-like convex lenses 3 in the present embodiment are formed so as to be aligned at a constant interval, the intervals may be random instead of constant.

As a method of forming the dot-shaped convex lens 3 on the surface of the transparent substrate 2, for example, a method of printing transparent ink on the surface of the transparent substrate 2, or embossing the transparent substrate 2 Examples of the method include a method of forming the transparent substrate 2 itself so that the convex lens 3 is formed, and a method of printing a photocurable transparent ink by a screen printing method is particularly preferable. According to the screen printing method, a photocurable transparent ink is printed on the surface of the transparent substrate 2 via the screen plate, and when the screen plate is separated from the transparent substrate 2, the printed photocurable ink is printed. Since the transparent ink adheres to the screen plate and is lifted, the photocurable transparent ink becomes a high convex lens shape. By irradiating light in that state to cure the transparent ink, the transparent ink is not crushed and becomes a convex lens 3 having a good shape.

In particular, in order to form the convex lens 3 having a height, the printing surface of the transparent substrate 2 is made to have a good slip property, the diameter of the convex lens 3 to be formed is increased, and a large amount of transparent ink is dropped. It is preferable to cure the transparent ink when the swell of the transparent ink reaches the peak due to the tension.

As the photocurable transparent ink, those which are usually used can be used, and particularly preferably, an ultraviolet curable transparent ink is used.

The glitter layer 4 needs to be in such a form that the glitter particles contained in the glitter layer 4 can reflect light incident from the transparent substrate 2 side. For this purpose, the glittering layer 4 is formed by dispersing glittering particles in a transparent matrix or a layer in which glittering particles are dispersed in a transparent matrix (the transparent substrate 2 side) and a desired opaque color. It is preferable that the glittering layer 4 is formed of a back layer composed of the following. The thickness of the glittering layer 4 is not particularly limited.

The transparent matrix is not particularly limited as long as it can be formed on the transparent substrate 2, and a material suitable for the material of the transparent substrate 2 can be appropriately selected and used.

The brilliant particles contained in the brilliant layer 4 reflect light to emit brilliant light, and may take any form such as a granular form, a powdery form, and a flake form. Examples of such brilliant particles include pearl pigments, metal pigments (metal particles), metal flakes, metal-coated flakes and particles obtained by coating a base material such as glass or plastic by depositing or plating metal. .

As the pearl pigment, besides the one using ordinary colored pearl particles, a pearl pigment whose color changes depending on the degree of light interference can be used. Examples of the metal pigment include an aluminum pigment, a gold pigment, and a silver pigment.

As the metal-coated flake, for example, a metal such as aluminum having a color tone such as gold or silver is deposited on a plastic film, and then a very small scratch-like pattern is formed.
There are hologram flakes and the like obtained by cutting or die-cutting the flakes. Such metal-coated flakes can emit rainbow-colored reflected light due to the action of the minimal scratch-like pattern.

Among the above glittering particles, it is preferable to use pearl pigments or hologram flakes, and by using such glittering particles, the color of each dot-shaped convex lens 3 or the change in the viewing angle is changed. A high brilliant feeling and a beautiful feeling in which a change or a change of light occurs can be obtained.

The particle size of the glittering particles is preferably from 5 to 150 μm, particularly preferably from 50 to 100 μm. If the particle size of the glittering particles is less than 5 μm, it is difficult to obtain a desired glitter, and if the particle size of the glittering particles exceeds 150 μm, the cost for producing the glittering particles or the cost required for forming the glittering layer 4 increases. .

In order to obtain the desired glitter, the amount of the glitter particles dispersed in the transparent matrix is preferably from 5 to 30% by weight, particularly preferably from 10 to 20% by weight. However, the present invention is not limited to this.

The method for forming the glittering layer 4 on the back surface of the transparent substrate 2 is not particularly limited. For example, screen printing, roll printing, gravure printing, offset printing, knife coater, spin coater, micro die,
Methods such as spray coating and brush coating are used.

In the glittering decorative body 1, the reflected light of the glittering particles is enlarged by the dot-shaped convex lens 3 so that the reflected light looks large and strong. Appear randomly in accordance with a change in the viewing angle, so that high glitter and beauty can be obtained. In addition, as the glitter particles, ordinary inexpensive particles can be used, and the glitter layer 4 can be formed on the transparent substrate 2 at low cost. It can be manufactured at low cost.

[0059]

EXAMPLES Hereinafter, the present invention will be described more specifically with reference to Examples and the like, but the scope of the present invention is not limited to these Examples and the like.

Example 1 On a surface of a transparent acrylic plate having a thickness of 2 mm, a screen plate of 250 mesh and a total thickness of 100 μm was used.
The V ink was screen-printed so as to form a dot group having a diameter of 0.5 mm and an interval of 0.35 mm. Immediately after that, the UV ink was irradiated to dry (cur) the UV ink. The diameter of the dot-shaped convex lens thus formed on the transparent acrylic plate is 0.5 mm, the height is 40 μm, and the interval is 0.35.
mm.

On the other hand, 20% by weight of a pearl powder having a particle size of 5 to 25 μm was mixed with a polyester-based transparent ink to prepare a pearl ink. Three kinds of pearl powder were used: (1) blue pearl only, (2) red pearl only, and (3) a mixture of red pearl and blue pearl at a weight ratio of 3: 1.

The right half is printed in black, and the left half is coated with the paper color (white) and the pearl ink is screen-printed using a 150-mesh polyester screen plate and dried. Was used as a glitter material.

When the reflected light of the glitter material thus produced was visually observed, it was found that both the right half (black on the back) and the left half (white on the back) and any pearl color had a pearly tone. Only faint reflected light was obtained, and no brilliant feeling due to strong reflected light was obtained. In addition,
The glittering material printed with pearl ink mixed with red pearl and blue pearl had a purple color close to brown.

The glitter material was adhered to the back surface of the transparent acrylic plate with a weak adhesive / removable adhesive, which was used as a decorative material. When the reflected light of the obtained decorative material was visually observed, the right half (back was black) was completely different from the glitter material.
In both the left and the left half (white background), blue pearls emit strong blue reflected light, red pearls emit strong red reflected light, and a mixture of blue pearl and red pearl emits strong blue reflected light and red With a strong reflected light, and a very high glitter and beauty were obtained.

The reason why the bright feeling due to the strong reflected light is obtained is that the dot-shaped convex lens magnifies the reflected light with small pearl particles by 20 to 100 times, and the apparent area of the reflected light becomes large. It is believed that there is.

Example 2 A brilliant powder was prepared in the same manner as in Example 1, except that a mixture of green pearl, gold pearl, red pearl and blue pearl in a weight ratio of 1: 1: 1: 1 was used as the pearl powder. Materials were created. When the reflected light of the glittering material was visually observed, the right half (black background) was slightly brown, and the left half (white background) was slightly pale brown, and almost no pearl-like reflected light was obtained. .

A decorative material was prepared in the same manner as in Example 1 using the above-mentioned glittering material. When the reflected light of this decorative material was visually observed, the green pearl, the gold pearl, and the red pearl both in the right half (black in the back) and the left half (white in the back) were completely different from the glittering material. And blue pearls respectively emitted strong reflected light of green, gold, red and blue, and very high glitter and beauty were obtained. In addition, even if the convex lens is at the same position, by changing the angle of the decorative material or the angle at which the decorative material is viewed,
Reflected light of another color appeared.

As described above, the green, gold, red, and blue colors emit strong reflected light because the respective pearl powders are not fused, and are reflected near the focal point of the dot-shaped convex lens. It is considered that the reflected light of any one of the green pearl, gold pearl, red pearl, and blue pearl particles looks enlarged.

Example 3 A pearl pigment (particle size: 5 to 40 μm) capable of changing its color from monotone to green color tone depending on the degree of light interference was applied to the same polyester-based transparent ink as in Example 1. 10% by weight
Pearl ink was prepared.

A pearl ink was screen-printed on a coated paper having the right half printed in black and the left half printed in blue using a 150-mesh polyester screen plate and dried to obtain a glitter. With respect to the glitter material thus produced, reflected light was visually observed while changing the degree of light interference, but almost no color change was observed.

The glitter material was attached to the back surface of the same transparent acrylic plate as in Example 1, and this was used as a decorative material. When the reflected light of this decorative material was observed while changing the degree of light interference, a strong reflected light of vivid green was obtained in the right half (black background), and a bright reflected light in the left half (blue background). Strong green reflected light and blue reflected light (pearl pigment was in a monotone state) were observed. Thus, in the present embodiment, 2
Reflected light that changed color was seen.

As can be seen from Examples 1 and 2, when ordinary pearl powder is used as the glittering particles, the same glittering and beautiful feeling can be obtained regardless of whether the back is black or white. Although the coloration of the back is not particularly problematic, as can be seen from Example 3, when a pearl pigment whose color changes according to the degree of light interference is used as the glittering particles, various colors can be obtained by changing the coloration of the back. And a brilliant feeling and aesthetic feeling of two-color change depending on the color.

Example 4 A hologram flake (particle size: about 50 μm, thickness:
2 to 3 μm) were mixed at about 5% by weight to prepare ramaki.

100 mesh, total thickness 130 on black paper
Using a screen plate of μm and a squeegee of hardness 65,
The above-described lamaki was screen-printed and dried to obtain a glitter material. When the reflected light of the glitter material thus formed was visually observed at a distance of about 30 cm, a large number of minute and glittering reflected lights were visible.

The glitter material was attached to the back surface of the same transparent acrylic plate as in Example 1, and this was used as a decorative material. When the reflected light of the decorative material was visually observed, the reflected light of the hologram flake was enlarged to about 10 times the size by the dot-shaped convex lens, and an extremely high glitter and beauty were obtained. The reflected light was clearly recognizable even when viewed from a distance of about 2 m.

[Example 5] The pearl ink or lamaki used in Examples 1 to 4 was printed on the back surface of the same transparent acrylic plate as in Example 1 to form a glittering layer. Was printed on the glittering layer to form a back layer. With the decorative material thus produced, the same brilliantness and beauty as in Examples 1 to 4 were obtained.

[0077]

According to the present invention, it is possible to obtain a glittering decorative body which can exhibit high glittering and beautiful feeling at low cost.
