Abstract

PURPOSE:To provide a mark having no restriction in color, a flat surface, a beautiful finish and a stereoscopic feeling. CONSTITUTION:A mark part B made of a character corresponding to a metal plate becomes dense in the degree of a color as compared with other part C so that there occurs a difference between light and shade of color between the part B and the other part C in such a manner that a pearl mica is further strongly repelled at a peripheral edge of the plate and a large quantity of the mica is put together on the periphery. Accordingly, a contour of the part B is clearly formed. Thus, the part B is so observed as to be recessed to generate a stereoscopic feeling on the entire mark A.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to markings and emblems to be mounted on the bodies of two-wheeled vehicles and four-wheeled vehicles, as well as posters, stickers, catalogs, etc., and three-dimensional marks and their production. It is about the method.

[0002]

2. Description of the Related Art Conventionally, a mark having a three-dimensional effect has been manufactured by forming irregularities on a preprinted mark and a specific portion around the mark. However, in this manufacturing method, since the surface of the printed matter becomes an uneven surface, the thickness of the printed matter becomes thick, and especially in the case of a mark used outdoors, dust or the like may be accumulated in the concave portion to make the mark unclear, There is an inconvenience that dirt is attached.

Therefore, a method of producing a mark having a three-dimensional appearance, that is, a surface having a flat surface, without giving unevenness, by expressing characters or figures (hereinafter referred to as a mark portion) by utilizing the action of magnetic force. Has been developed and put into practical use. In this method, iron oxide particles that are attracted by magnetic force are contained in the printing ink, and the printing ink is used to print on a printing object such as paper or a plastic sheet. It is considered that the distribution amount of iron oxide particles is made different by concentrating on the mark portion from the lower surface side of the printed material by magnetic force or conversely concentrating on the portion other than the mark portion.

[0004]

However, the conventional mark manufacturing method utilizing the magnetic force described above has the following disadvantages.

Since the color of iron oxide is limited to yellow, brown, black, etc., the color of printing ink is limited.

Processing for generating a magnetic force corresponding to a mark portion such as a character or a pattern requires a great deal of labor and cost.

The present invention has been made in view of the above points and provides a mark having a flat surface, a beautiful finish, and a three-dimensional effect without any color restriction, and for expressing the mark portion three-dimensionally. It is an object of the present invention to provide a manufacturing method capable of manufacturing a mark having a three-dimensional effect, which is easy to process, has no design limitation, and can be manufactured at a low price.

[0008]

Means for Solving the Problems In order to achieve the above object, the three-dimensional mark of the present invention comprises: a) paint or printing containing reflective pigment particles such as pearl mica and aluminum powder. A coating layer of ink for ink, and b) a high voltage is applied to the reflective pigment particles in the coating layer in a predetermined mark portion composed of characters or patterns and a portion other than the mark portion, and the pigment particles are applied. The distribution amount of is different.

The mark manufacturing method of the present invention comprises: A) mounting an electrically conductive metal plate having a shape corresponding to an arbitrary mark portion composed of characters or patterns on an insulating substrate such as a synthetic resin plate, This metal plate is grounded, B) on the substrate, an object to be coated such as a transfer film is placed, and a paint or printing ink containing reflective pigment particles such as pearl mica and aluminum powder is used. , Apply to the entire surface of the object to be coated,
C) A high voltage is applied to the applied layer before the applied paint or printing ink is dried.

Further, as described in claim 3, an arbitrary mark portion composed of characters and patterns is printed on a film such as A ') transfer film with a printing ink having an electric resistance value of about 1 to 10 MΩ. , B ') A paint or printing ink containing reflective pigment particles such as pearl mica and aluminum powder is applied to the entire surface of the film, and C').
It is also possible to apply a high voltage to the applied layer before drying the applied coating material or printing ink.

As described in claim 4, c) the electric resistance value of the paint or printing ink is preferably 150 MΩ or less.

Further, as in claim 5, D) -60 to-from a position 10 to 20 cm away from the surface of the coating layer.
It is preferable to apply a direct current voltage of 90 kV.

[0013]

According to the mark of the present invention having the above structure,
The distribution amount of the reflective pigment particles in the mark portion contained in the coating layer and the distribution amount of the reflective pigment particles in the portion other than the mark portion are different depending on the application of the high voltage. Therefore, the reflectance of the pigment particles is different between the mark portion and the other portion, and this mainly appears as a difference in shade of color, which gives a perspective feeling to the entire mark and gives a stereoscopic effect. Here, taking the case of using pearl mica as the pigment particles as an example, the pearl mica pigment particles are aggregated in the parts other than the mark part, and conversely, the distribution amount of the pearl mica pigment particles is significantly reduced in the mark part. Therefore, as shown in FIG. 1, the mark portion appears to be recessed as compared with the periphery thereof, the periphery of the mark portion is lifted up from the mark portion, and the entire mark becomes three-dimensional and deep.

According to the mark manufacturing method of the present invention (claim 2), the applied paint or ink is undried with respect to the applied layer of the object to be painted placed on the insulating substrate, When a high voltage is applied, the pigment particles in the coating layer are electrostatically charged. While the substrate is insulated and has no electrical conductivity, the metal plate corresponding to the mark part of the substrate is grounded, so it is located above the metal plate of the object to be coated placed on this. The pigment particles in the applied layer cause electrostatic repulsion to the metal plate and escape to the substrate side. In particular, the electrostatic repulsion is large at the periphery (edge portion) of the metal plate, and the pigment particles are repelled more strongly, and the distribution amount of the pigment particles is greatly reduced as compared with other portions. On the other hand, since the pigment particles in the coating layer repelled by the metal plate are aggregated on the substrate, the pigment particles of the coating layer on the substrate and the pigment particles on the metal plate have different distribution amounts thereof, Mainly reflectance (including gloss and brightness) due to the reflectivity of pigment particles
Difference occurs in the mark part and other parts, and it appears as a light and shade difference in color, and since a large amount of pigment particles are concentrated especially on the boundary line between the substrate and the metal plate, the outline of the mark part is clear. Appear in. In this state, the paint or ink in the coating layer dries to maintain the distribution of pigment particles.

Incidentally, the principle of this manufacturing method is that, particularly in low humidity in winter, a resin as a material to be coated hung by a metal hanger is used as a coating material containing reflective pigment particles. This is what utilizes the so-called flower bloom phenomenon, in which, when spraying and coating, only a portion (contact point) where the hanger comes into contact produces a shaded pattern different from other portions. In other words, since the resin is charged with static electricity and the contact point of the resin hanger is in a kind of earth state, the pigment particles in the sprayed paint are electrostatically charged against the contact of the hanger on the resin. Repulsion occurs, and the repulsion (escape) area of the pigment particles spreads out in a substantially radial shape around the contact point of the hanger. The phenomenon in which the repulsion area of the pigment particles is darker than the other areas and a difference in shade occurs between the two is utilized.

According to the manufacturing method of the third aspect,
When the film is thick and lacks electrical conductivity, the mark is produced by the action substantially similar to the action of the production method of the above-mentioned claim 2. That is, when a high voltage is applied,
The pigment particles in the coating layer are electrostatically charged, but the mark portion with a very low electric resistance value printed on the film acts like the above-mentioned grounded metal plate and is charged. Since the pigment particles are electrostatically repulsed, the distribution amount of the pigment particles is different between the mark portion and the other portion, and a difference in shade of color appears.

According to the manufacturing method of claims 4 and 5, the pigment particles in the coating layer located on the metal plate or the ink having a low electric resistance value are reliably electrostatically repelled.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a mark having a three-dimensional effect according to the present invention will be described below together with an embodiment of its manufacturing method with reference to the drawings.

FIG. 1 is a front view showing a mark of this embodiment, FIG. 2 is a front view showing a substrate used to manufacture the mark of FIG. 1, and FIG. 3 is a schematic view of a manufacturing mode of the mark of FIG. It is sectional drawing shown.

As shown in FIG. 2, the substrate 11 is made of an insulating material made of synthetic resin, and the substrate 11 is formed of a thin metal that constitutes a mark portion such as letters (here, characters of Kawasaki (registered trademark)). The plate 12 is embedded so as to be flush with the surface of the substrate 11, and the ground wire 13 is connected to the metal plate 12. As the metal plate 12, a copper plate, a silver plate, an aluminum plate or the like having excellent electrical conductivity is used.

On the substrate 11 thus formed, as shown in FIG. 3, the transfer paper 1 having the adhesive layer 2 applied on the mount 3 is placed. Then, a layer having a uniform thickness (about 2 to 20 μm) is printed on the entire surface of the adhesive layer 2 with the printing ink 4 containing, for example, pearl mica 5 as pigment particles. The printing ink 4 has an electric resistance value of 15
Inks of 0 MΩ or less, for example, made of melamine / acrylic resin for each color are used. The compounding ratio (weight ratio) of the ink 4 and the pearl mica 5 is ink: 80 to 90%,
Pearl car: 20 to 10%.

In the above state, a high voltage is applied to the ink 4 by the following procedure. That is, a low voltage (about 50 μA) high voltage (−60 to −90 k) generated using a DC power supply.
v) from the position where a constant distance (10 to 20 cm) is distant from the entire surface of the ink 4 on the substrate 11, and
Is applied uniformly via.

As a result, the pearl car 5 in the ink 4
Is charged with static electricity and is charged, so pigment particles 5
Is electrostatically repulsed by the grounded metal plate 12 of the substrate 11, and the pearl mica 5 escapes from the metal plate 12 and is collected on the substrate 11 side. In this way, the reflectance (including gloss and brightness) is increased at the location where the pearl mica 5 is aggregated (substrate 11) due to the reflectivity of the pearl mica 5.
On the contrary, since the reflectance is weakened at the place where the pearl car 5 escapes (the metal plate 12), the reflectance at the mark portion B of the mark A becomes smaller than that at the other portion C as shown in FIG. Areas C other than B appear to shine.

For this reason, as shown in FIG.
In the mark portion B composed of the characters corresponding to (FIG. 2), the degree of color is darker than in the other portion C, and the difference in shade between the mark portion B and the other portion C occurs. At the periphery, the pearl car 5 is more strongly electrostatically repulsed, and a large amount of the pearl car 5 is caused by the metal plate 12 and the substrate 1.
The outline of the mark portion B is formed sharply because it is concentrated near the boundary line of 1. As a result, the mark portion B looks like a depression, and the mark A as a whole has a three-dimensional effect.

After the ink 4 is completely dried, a durable transparent ink (clear ink) 6 or a film such as vinyl chloride or polypropylene is attached to protect the printed layer of the ink 4. If so, the production of mark A (FIG. 1) is completed. When the mark A is attached to the vehicle body or the like, the adhesive layer 2 can be exposed and attached by wetting the backing sheet 3 with water and peeling it off.

By the way, the reason why the printing ink 4 having an electric resistance value of 150 MΩ or less is used is that an ink having an electric resistance value of more than 150 MΩ hardly causes the above phenomenon when a high voltage is applied. Because it will be.

Next, an embodiment of a mark and its manufacturing method according to another embodiment will be described with reference to the drawings.

FIG. 4 is a cross-sectional view schematically showing a mode of manufacturing a mark using a thick film. As shown in FIG. 4, the adhesive layer 23 provided on the lower surface of the thick film 22.
Then, the release paper 24 is attached to the printed film 21. A mark portion such as a character or a figure is printed on the surface of the film 22 of the printing film 21 with the ink 25 having a low electric resistance value (about 1 to 10 MΩ). After the ink 25 dries, the film 2 is formed by the ink 26 containing the metallic powder 27 having a reflective property of a metallic pigment 27 (10 to 20% by weight) and having an electric resistance value of 150 MΩ or less.
Print on the entire surface of 2. Then, before the ink 26 dries, a low current (50 μA
A high voltage (−60 to −90 kv) is applied uniformly from a position separated by a constant distance (10 to 20 cm) via the discharge electrode plate 14.

As a result, the aluminum powder 27 in the ink 26 is
Is electrostatically charged, and the aluminum powder 27 is electrostatically repelled by the ink 25 in the mark portion on the film 22 where the electricity most easily flows, and the aluminum powder 27 escapes from the ink 25 in the mark portion. As a result, the aluminum powder 27 is collected on the mark portion (on the film 22) other than the ink 25. Then, after the ink 26 is completely dried, a durable transparent ink (clear ink) 28 is applied to complete the production of the mark A ′. When the mark A ′ is attached to the vehicle body or the like, the release paper 24 may be peeled off to expose the adhesive layer 23 and then attached.

The mark A'according to this embodiment also has a reflectance similar to that of the mark A (FIG. 1) of the above embodiment, which is inferior to that of the other portions, and appears dark, so that the mark 25 has a marked color. Has a concave appearance compared to other parts, and the mark A ′ has a three-dimensional effect. Such an effect is that in the case of the mark A ′ of the present embodiment, the ink 25 at the mark portion is grounded, as compared with the case of the manufacturing method (FIG. 3) of the mark A (FIG. 1) of the first embodiment. The sensitivity (definition) of the mark portion is slightly inferior because there is nothing (the metal plate 12 is grounded), but basically there is no change.

In addition, when a mark of the above type is directly provided on the surface of a synthetic resin such as a vehicle body part, although not shown, the mark portion showing characters or patterns has a low electric resistance value (1 to 1). About 10 MΩ) Ink or paint is used to print or apply on the surface of the synthetic resin, or a mark portion is formed with a thin metal plate and is attached to the surface of the synthetic resin. Then, a paint or printing ink containing reflective pigment particles such as pearl mica and aluminum powder is applied on it to a certain thickness, and a high voltage is applied before the applied layer dries. Good. At this time, it is more effective to connect the ground wire to the mark portion.
Note that, for example, in the mark A of FIG. 1, if the portion C other than the mark portion B is formed of the metal plate 12 instead of forming the mark portion B of the metal plate 12, the mark portion B appears to be lifted, which is completely opposite. A three-dimensional mark of the aspect can be obtained.
