JPS59126435A - Nameplate having metallically decorated light-screening part and its preparation - Google Patents

Abstract

PURPOSE:To prepare an inexpensive nameplate having metallically decorated light-screening part more simply, by forming partially metallized layers on a transparent synthetic resin plate with pattern so that light-screening parts are made. CONSTITUTION:The given patterns 2 are made on the surface of the transparent synthetic resin plate 1 (e.g., polystyrene resin, etc.), the releasing agent (e.g., monomer of silicone resin, etc.) 3 is applied to a part to be processed into a transparent part, the transfer sheet 8 consisting of the substrate film (e.g., cellophane, etc.) 7, the releasing agent layer (e.g., chlorinated rubber, etc.) 6, the metallized layer (e.g., aluminum, etc.) 5, and the adhesive layer 4 is superimposed on the plate, they are pressed, and the substrate film 7 is released and removed, to give the desired nameplate having a metallically decorated light-screening part. USE:Electric appliances, acoustic facilities, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a nameplate for use as a display part by shining light from the back side, which is used for electrical equipment, audio equipment, etc., and a method for manufacturing the nameplate.

-Most of the nameplates used for electric appliances, sound instruments, etc. are made of metal plates, and their metallic luster is considered desirable in terms of design. When it is necessary to install a transparent part on the back side of such a metal nameplate for illumination or other purposes, a penetration part is provided in the metal plate by punching or etching, and the penetration part is covered with a transparent temporary material. However, this method requires a large number of steps, and is disadvantageous in terms of production efficiency and the number of parts used.
~Causes swelling.

The present invention has been made to overcome the drawbacks of the prior art.
By providing layers, it is possible to provide a method for manufacturing a nameplate more easily and a nameplate at a lower cost.

The present invention will be described in detail below with reference to the drawings.

First, as shown in Figure 1, a desired pattern (2) is applied to the surface of a transparent synthetic resin plate (1), and then a mold release agent (3) is applied to the area that should become the transparent part, as shown below. Overlap the composition transfer sheets.

That is, as shown in FIG. 2, a transfer sheet (8) consisting of a support film (7), a release agent layer (6), a metal vapor deposition layer (5), and an adhesive layer (4) is placed on the synthetic resin plate. When the supporting film is peeled off after being heated and pressed, the pattern forming surface of the synthetic resin plate is coated with metal vapor @, except for the part where the mold release agent (3) is applied, as shown in Figure 3. The layer is transferred, and that part becomes a light-shielding part.

Next, to explain each material used in the present invention, first, as a transparent synthetic resin plate, polystyrene resin, ABS resin,
Acrylic resin, polyvinyl chloride resin, polynisder resin, polycarbonate resin, etc. are used, and the release agent applied thereon is silicone resin alone, an ink-like product containing silicone resin as a binder, or a wax-based release agent. A mold release agent or its compound, or a resin that temporarily adheres to a transparent synthetic resin plate such as polyamide resin,
Alternatively, a curable resin that does not adhere to a transfer sheet or adhesive such as alkyd resin or modified melamine resin may be used.

The support film for the transfer sheet is made of cellophane, oriented polyethylene, oriented polypropylene, oriented polyester, etc., and the release agent layer formed on the support film is chlorinated rubber, acrylic, etc. The metal vapor deposited layer includes aluminum, nickel,
Acrylic, ethylene vinyl acetate, and the like are used as the adhesive layer formed on chromium, alloys thereof, and the like.

The nameplate of the present invention having the above configuration has the following effects.

■It does not require many processes such as punching out or etching a metal plate, and is manufactured by applying a mold release agent and transferring a metal vapor deposited layer, which not only reduces costs, but also allows accurate formation of light-shielding parts and light-shielding parts. It's a monkey.

■Since the light shielding part is formed of a metal vapor deposited layer, the same design effect as using a metal plate can be obtained.

■Since the light-shielding part is formed by a transfer method, it can be produced continuously and efficiently, leading to cost reductions.

[Brief explanation of drawings]

The drawings show examples of the present invention, in which Fig. 1 is a cross-sectional view of a synthetic resin plate with a pattern and a mold release agent formed on its surface, and Fig. 2 is a cross-sectional view of a synthetic resin plate used for forming a metal vapor deposition layer. A cross-sectional view of the transfer sheet, Figure 3, does not show the state in which the metal vapor deposited layer is being transferred.

Claims (2)

[Claims] (1) A nameplate whose light-shielding portion is decorated metallic, characterized in that the light-shielding portion is formed by partially providing a metal vapor-deposited layer on a transparent synthetic resin plate with a desired pattern. (2) Apply a desired pattern to a transparent synthetic resin plate, then apply a mold release agent to the area that should be the transparent part, and then lay a transfer sheet with a metal vapor deposited layer on top of it and apply the mold release agent. A method for producing a nameplate having a metallically decorated light-shielding part, characterized in that a metal vapor deposition layer is transferred only to the uncoated part, and 81S of the metal vapor-deposited layer is used as a light-shielding part.
