Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative member that is decorated by forming a colored pattern on a surface thereof, such as an elevator landing door, a car door, and a cabin wall, and a method of manufacturing the same.

[0002]

2. Description of the Related Art Conventionally, for example, when manufacturing a decorative panel made of metal, after an ink receiving layer is provided on the surface of a metal plate, a colored pattern is formed on the ink receiving layer by an ink jet printer, and the surface is transparent. Coated with a protective film layer (clear). Thereafter, the metal plate is processed into a predetermined panel shape, and a reinforcing material is welded to the back surface as necessary. There is also a method in which after a metal plate is processed into a panel shape, an ink receiving layer is formed on the surface and a colored pattern is printed.

[0003]

In the above-described conventional method of manufacturing a decorative panel, a coloring material is directly printed on the surface of a metal plate using an ink jet printer, so that a colored pattern is formed on a curved surface or a bent portion. I couldn't.
In addition, in order to form the ink receiving layer uniformly, it is necessary to increase the surface accuracy of the metal plate, and it is not possible to coat the ink receiving layer on the metal plate in a large amount, which increases the cost. . Furthermore, if a problem occurs before the printing process, it is impossible to start over.

[0004] Further, when bending is performed after the printing process, cracks may be formed in the bent portion and the surface of the pattern may be damaged by the machine tool during the processing. Further, the heat for welding the reinforcing member and the stud bolt may deteriorate the ink receiving layer or distort the colored pattern.

On the other hand, there is a method in which a colored pattern is printed on a transparent film and the film is attached to a metal plate. In this case, however, it is not possible to attach the film to a secondary curved surface such as a spherical surface. In addition, since a pressure-sensitive adhesive was used, re-attachment was not possible, and positioning was extremely difficult. In addition, air bubbles easily enter between the film and the metal plate, making it difficult to perform the attaching operation.

The present invention has been made to solve the above problems, and has various shapes,
Colored patterns can be easily formed on the base material,
An object of the present invention is to obtain a decorative member and a method for manufacturing the same, which can reduce the manufacturing cost.

According to a first aspect of the present invention, there is provided a decorative member comprising a base material, a thermoplastic resin layer thermally fused to the base material, and a thermoplastic resin layer provided on the thermoplastic resin layer. And a coloring material provided in the ink receiving layer and forming a colored pattern.

[0008] A decorative member according to a second aspect of the present invention uses a transparent thermoplastic resin layer.

According to a third aspect of the present invention, there is provided a method for manufacturing a decorative member, comprising forming a thermoplastic resin layer, an ink receiving layer provided on the thermoplastic resin layer, and a colored pattern provided on the ink receiving layer. And a step of coating the surface of the substrate with a colored film having a coloring material and a step of heat-sealing the thermoplastic resin layer to the substrate by heating the colored film.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view of a metal decorative panel according to an embodiment of the present invention. In the figure, a rust-preventing layer 2 is formed on the surface of a metal plate 1 as a substrate to prevent the metal plate 1 from rusting and to secure paint adhesion. On the rust preventive layer 2, a colored paint layer 3 of a base color is formed.

On the colored paint layer 3, a colored film 4 on which a colored pattern is formed is adhered. The coloring film 4 includes, for example, a thermoplastic resin layer 5 made of a transparent sheet-like acrylic resin, an ink receiving layer 6 provided on the thermoplastic resin layer 5, and a coloring layer provided on the ink receiving layer 6. It is composed of a coloring material 7 forming a pattern. The ink receiving layer 6 is made of, for example, a high-quality recording medium using porous alumina in which a large number of linear pores are formed by orienting non-spherical alumina fine particles. On the colored film 4, a transparent clear paint layer 8 for surface protection is formed.

Next, a method of manufacturing the metal decorative panel shown in FIG. 1 will be described. First, as shown in FIG. 2, an ink receiving layer 6 is applied on a thermoplastic resin layer 5 and fixed by heating.
Next, as shown in FIG. 3, a color pattern by the colorant 7 is printed on the ink receiving layer 6 by the ink jet printer 10 connected to the computer 9, and the color film 4 is manufactured. Here, the melting temperature of the thermoplastic resin layer 5 is higher than the heat-fixing temperature of the ink receiving layer 6, and the thermoplastic resin layer 5 is not melted by heat during printing by the inkjet printer 10.

On the other hand, as shown in FIG. 4, a flat metal plate 1 cut into a predetermined size is bent into a predetermined panel shape as shown in FIG. Further, a reinforcing material or the like is fixed to the back surface as necessary. Thereafter, as shown in FIG. 6, a base coat, an intermediate coat and, if necessary, a top coat are applied to form a rust preventive layer 2 and a colored paint layer 3 on the panel. The surface of the colored paint layer 3 is polished as shown in FIG. 7 to increase the flatness of the panel surface.

Next, as shown in FIG. 8, the colored film 4 of FIG. 3 is overlaid on a predetermined position on the panel of FIG. In this state, as shown in FIG. 9, the panel is heated in the heating furnace 11, and the thermoplastic resin layer 5 is melted. Thereafter, the thermoplastic resin layer 5 is cooled and hardened. This allows
The thermoplastic resin layer 5 is thermally fused to the panel surface. next,
As shown in FIG. 10, the top coat is applied on the colored film 4 to form the clear paint layer 8. Finally,
As shown in FIG. 11, the surface of the clear paint layer 8 is polished to complete a metal decorative panel.

In such a metal decorative panel, since the thermoplastic resin layer 5 of the colored film 4 is heat-sealed on the metal plate 1, a colored pattern is easily formed on the bent portion of the metal plate 1. In addition, a colored pattern can be similarly formed on a secondary curved surface such as a spherical surface. Therefore, the metal plate 1 can be processed into a panel shape in advance, and there is no possibility that the colored pattern is cracked or damaged. further,
Reinforcing members and stud bolts can be welded in advance, and the ink receiving layer 6 does not deteriorate and the colored pattern does not become distorted.

Further, before the heat-sealing, the colored film 4 can be easily peeled off, so that the redoing and the positioning are easy. In addition, if there is a problem in the printing stage, it is possible to start over at the cost of only the colored film 4.

Further, since the coloring material 7 is directly printed on the ink receiving layer 6 by the ink jet printer 10, a clear colored pattern with high resolution can be easily formed. Furthermore, since the transparent thermoplastic resin layer 5 is used, a design in which a colored pattern is formed on a base color can be easily obtained.

The material of the base material is not limited to metal, but may be, for example, pottery or wood. Further, the shape of the base material is not limited to a flat shape or a panel shape, and may have a curved surface, a spherical surface, or fine irregularities. In this way, the same colored pattern can be applied to substrates of different shapes and materials, and the technical range is wide.

Further, the material of the thermoplastic resin layer 5 is not limited to an acrylic resin, but may be, for example, a polyester resin or a modified polyolefin resin.
