Description

[Detailed Description of the Invention] The present invention relates to a metal decorative board, and more specifically, to a metal decorative board having a three-dimensional effect and interference fringes.

Conventional metal decorative boards are those in which a transparent film with a printed pattern is pasted onto a metal flat plate as a base material, or those in which a printed pattern is applied by an appropriate printing method after forming a transparent resin layer. However, since both are simply flat patterns on a flat metal plate, they lack a three-dimensional effect and have extremely low commercial value.

The present invention eliminates such drawbacks and provides a metal decorative board with extremely high commercial value, and will be described in detail below with reference to the drawings.

That is, the metal decorative board of the present invention, as shown in FIG. 1, has a transparent resin film 4 having a dye penetration image 3 laminated on a metal plate 2 having a fine uneven pattern 1.

The method for manufacturing the decorative metal laminate of the present invention will be explained below.

The metal plates that can be used in the present invention are aluminum plates, stainless steel plates, etc. The means to create a fine uneven pattern on the surface of such metal plates is to create a hairline pattern by directly scraping the surface of the metal plate with a rotating hard brush. There are physical processes such as spin processing, in which the surface of a metal plate is directly ground and polished by a rotating spin, and chemical etching processes, such as corrosion.

A transparent resin such as polyester, epoxy, polycarbonate, etc. is dyed with a sublimable, vaporizable, or melt-transferable heat transferable dye on a metal plate having a fine uneven pattern obtained by using such a method. Forms a resin film of urethane, acrylic, nylon, etc.

Here, the method for forming the transparent resin film may be any commonly used coating method, specifically coating methods such as brush coating, roller brush coating, flow coating, spray coating, and roll coater coating.

Next, as means for forming a penetrating image using a dye on a transparent resin film, there are the following methods.

That is, as shown in FIG. 2, a transfer sheet 6 on which an appropriate transfer pattern 5 is formed with an ink containing a heat-transferable dye, such as sublimation, vaporizability, or melt-transferability, which is capable of penetrating into the resin, is transparent. The transparent resin film 4 is closely attached to the resin film 4 and then heated to a temperature at which the heat transferable dye is thermally transferred.
The transfer is completed by transferring and infiltrating the transfer sheet 6, and then peeling off the transfer sheet 6.

Through this transfer process, the heat transferable dye permeates into the transparent resin film 4, forming a permeation image.

Here, the sheet base of the transfer sheet may be paper such as Western paper (wood-free paper, medium-quality paper, corrugated paper, art paper, coated paper, gravure paper, etc.), Japanese paper (heavy paper, etc.), non-woven fabric, film, metal foil, etc. Can be used.

Next, as a second method, as shown in FIG. 3, an ink containing a transparent binder resin and the heat transferable dye is directly printed on the transparent resin film 4, by means such as gravure. The printed pattern 7 is formed by printing using a printing method or the like, and the printing is then completed by heating until the heat-transferable dye permeates into the transparent resin film 4.

Through this printing process, the heat transferable dye permeates into the transparent resin film 4 to form a permeable image.

In addition, heat transferable dyes such as sublimation, vaporization, and melt migration properties include disperse dyes, cationic dyes, oil dyes, etc. Specifically, Diamond Seriton Pink B1 Diamond Seriton Violet Station (Mitsubishi Kasei (manufactured by Kikisha), Sumikalon Yellow E-FG (manufactured by Sumikata Chemical (manufactured by Kikisha), Eisenkatilon Yellow 3GLH, Eisenkatilon Red □□
□F (manufactured by Hodogaya Chemical Co., Ltd. (Kikusha)), Plastiviolet 8840 (manufactured by Yusui Chemical Co., Ltd. (Kikusha Co., Ltd.), etc.).

Since the present invention has the above configuration, the fine uneven pattern on the metal plate and the penetration image in the transparent resin film interfere with each other, resulting in a three-dimensional effect.

Therefore, it has a wide range of applications as a decorative material for jars, pots, light cabinets, etc., and has great practical effects.

Examples are shown below. Example 1 A fine uneven pattern was formed on the surface of an aluminum plate by double spin processing.A transparent acrylic baking type paint was applied on the surface using a roll coater, and baked at 190°C for 1 minute to form a transparent resin film. Formed.

Next, Sumikaron Yellow E-FC, and Hc. 1, N
o, Disperse Red5Q, same (Blue5
Using a transfer paper on which an appropriate transfer pattern was formed using an offset ink containing heat transferable dye No. 4, it was brought into close contact with the surface of the transparent resin film and heated at 190°C for 3 hours to form a penetration image within the film. .

The obtained decorative board had a three-dimensional effect and was beautiful.

Example 2 The same offset ink used in Example 1 was used to directly print on the coated surface of an aluminum plate on which the transparent resin film created in Example 1 was formed, and then heated at 190°C for 30 seconds to remove the film. A penetrating image was formed inside.

The decorative board obtained was equivalent to that of Example 1.
