[Means for Solving the Problems] The technical means taken by the present invention to achieve the above-mentioned object is to adsorb by magnetism such as iron in a clear paint or a candy paint (transparent colored paint). Prepare a paint mixed with fine metal powder, and place and fix a magnetic generator that generates magnetism along the desired design shape on the back side of the workpiece (design target) made of non-magnetic material that is not attracted to magnetism. Then, by applying the above-mentioned paint from the front side of the work piece, the powder of the powder mixed in the paint is subjected to permutation according to the magnetic field.

Examples of the magnetic generator to be arranged and fixed on the back side of the above-mentioned work include magnets, electromagnets wound with coils, other magnetic generators, and the like. Further, metal fine powder to be blended in the clear paint is used. The size is smaller than the thickness of the coating film formed by one coating, for example, about 25 microns or less, and the form of the fine metal powder is preferably flat powder, for example, flat amorphous metal powder. Further, regarding the color, the case where a transparent color (candy color) is applied to the paint itself and the case where the powder itself is colored (for example, red and blue) by forming an oxide film on the surface of the fine metal powder to be blended Of course, it is possible to combine the two to create a multicolored design.

According to the above-mentioned means, a magnetic field is generated from the north pole to the south pole of the magnetic generator disposed on the back side of the work piece, whereby the paint applied to the surface of the work piece is Of the metal fine powders that are blended, the powder of the part affected by magnetism is arranged in a permutation according to the magnetic field, and arranged.
The powder that is not affected by magnetism is randomly arranged. That is, in the vicinity of the center of the magnetic field, the fine metal powder is adsorbed and held substantially at right angles to the surface of the work piece, and the fine metal powder gradually becomes horizontal with respect to the work piece from the center to the peripheral direction. The powder is irregularly arranged in a portion which is supported at an inclination and is not affected by magnetism.

By arranging the array of fine metal powders in order according to the design, shadows and reflections due to the same light as a three-dimensional object are performed, so a design that makes the solid illusion at any angle is completed regardless of the viewing direction. To be done.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings for coating a helmet. First, as shown in FIG. 1, a magnet (a disk-shaped magnet is shown in the drawing) 2 of a magnetic generator is placed on a back side of a cap body 1 made of a non-magnetic fiber-reinforced resin material with a tape 3 at a predetermined position. Place and fix. Further, as shown in FIG. 2, the paint 4 applied to the surface of the cap body 1 is formed by mixing a clear paint or a transparent colored paint 4a with a magnetically adsorbed flat metal fine powder 4b. . As the flat metal fine powder 4b to be mixed with the paint, one having a high aspect ratio is effective. The aspect ratio is represented by the ratio of the long diameter (L) and the thickness (T) of the powder,
The higher the aspect ratio = L / T, the brighter the powder.

The paint 4 containing the fine metal powder 4b is shown in FIG.
As shown in FIG. 3, a coating 5'is formed on the surface of the cap body 1 by spraying and applying it on the front side of the cap body 1 on which the magnetic generator 2 is arranged. By the way, since a magnetic field is generated from the N pole to the S pole in the magnetic generator 2 arranged on the back side of the cap body 1, as shown in FIG. Among them, the metal fine powder in the portion affected by the magnetism is arranged in a permutation according to the magnetic field and arranged to form a pattern, and the metal fine powder in the portion not affected by the magnetism is irregularly arranged.

That is, that is, in the vicinity of the center of the magnetic field, the metallic fine powder 4b is adsorbed and held at a substantially right angle to the surface of the cap body 1,
From the center to the peripheral direction, the fine metal powders 4b are supported by being gradually inclined horizontally with respect to the cap body 1, and the powders are irregularly arranged in a portion that is not affected by magnetism.
When the thickness of the coating film formed in the above-mentioned one-time coating process is substantially the same as the size of the metallic fine powder 4b, the surface of the portion where the metallic fine powder 4b stands is rough. If this is the case, as shown in FIG. 5, the clear paint 6 is applied by spraying on the coating film 4'to make the surface smooth. If the size of the fine metal powder 4b mixed in the coating material 4a is smaller than the film thickness formed in one coating step, the surface of the coating film will not be rough and the clear coating material Does not need to be applied in layers.

The design obtained by the above coating method is shown in FIG.
When the design is viewed from the center line, which is formed in a circular shape and is formed as shown in, the center part is the fine metal powder 4b.
Since there is no reflection of light on the metal powder, the ground color of the metal powder appears, and since the fine metal powder inclines from the center of the circle to the edge, light is reflected by the inclined surface and the edge of the design is Glowing and contoured. That is, since the arrangement of the fine metal powders 4b is permuted according to the design, shadows and reflections due to the same light as a three-dimensional object are performed, so that the design obtained by this coating method can be applied to any direction regardless of the viewing direction. The effect of illusion of a solid is obtained at an angle. or,
If you use a transparent colored paint, or a powdered metal powder with an oxide film formed on the surface of the powder, the powder itself is colored. It is possible to complete a multi-colored design in a short time without having to dry, dry, etc.
