Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative body for an automobile, and more particularly to a decorative body in which a back surface of a display body made of a transparent synthetic resin is magnetically coated.

[0002]

2. Description of the Related Art A method of forming a paint pattern using a paint containing a powder of a magnetic material is disclosed in, for example, JP-A-63-175650.
It is conventionally known as described in Japanese Patent Publication No.

[0003]

However, the coating pattern using the magnetic material powder disclosed in JP-A-63-175650 is merely a representation of characters, marks, and designs as it is, and lacks in interest. was there. An object of the present invention is to provide a new decorative body having an excellent aesthetic property, which has a painted surface of a ground pattern that changes in shade as the viewpoint moves.

[0004]

SUMMARY OF THE INVENTION The present invention relates to a decorative body comprising a transparent base having a convex surface on the front side and a coating film formed on the rear side of the base. It has a dent of a portion to be a chapter, an aluminum film is provided on the bottom surface of the dent, and the magnetic material powder approaches the peripheral portion on the entire rear surface side of the light-transmitting substrate, with the magnetic material powder being irregular at the center. , The coating film contained in a state of being gradually aligned in the vertical direction is provided.

[0005]

1 to 5, which schematically show the manufacturing process of an embodiment of a decorative body according to the present invention, reference numeral 1 denotes a transparent substrate made of acrylic, which is to be the front side of the product (the lower surface in the figure). ) Is in the shape of a lens with a small height at the center, and the surface to be the reverse side (the upper surface in the figure)
Is a uniform plane except for the part that should become a concave mark.

[0006] On the surface to be the back side of the substrate, an aluminum vapor-deposited film 2 is first formed on the entire surface, and thereafter, an etching resist film 3 is buried in a depressed portion to become the mark. Further, the aluminum deposition film excluding the portion where the etching resist film is formed is removed by an etching process to form a desired mark.

Next, a blue paint containing nickel powder as a magnetic material is applied to the entire surface of the substrate to be the rear surface by a conventional method. The substrate on which the coating film 4 is formed in this manner is placed in the center of a magnetic field formed by a magnet as described later before the coating film is cured. In addition, a backing coating is further applied on the coating film after curing, if desired.

FIG. 6 shows the positional relationship between the base and the magnet according to this embodiment. The magnet in this embodiment is one in which flexible permanent magnets 5 are arranged in a ring around the base.
Although the action of the magnetic field generated by the magnet affects the nickel powder on the periphery of the coating surface close to the magnet, the coating hardens before the nickel powder is displaced by the action of the magnetic field. Therefore, the effect of the magnetic field is not substantially exerted on the nickel powder at the center of the coating film surface away from the magnet.

[0009]

In the decorative body thus formed, the nickel powder is fixed in a state of being dispersed irregularly at the center of the coating film surface, and the nickel powder is affected by the magnetic field as it approaches the periphery. And is fixed in a state of standing upright in the direction perpendicular to the coating film surface. When the decorative body is viewed from obliquely above the surface, the painted surface can be seen as a ground pattern behind a metallic luster mark, and the ground pattern is darker at the front edge than at the rear edge. The darker portion then becomes lighter toward the center, and the darker position moves to a position closer to the front on the peripheral portion as the viewpoint of the viewer shifts.

[0010]

Advantages of the Invention Since the present invention is configured as described above, it is possible to provide an aesthetically pleasing decorative body in which the shade position of the coating film surface moves as the viewpoint moves.
