Some have patterns such as pictures. In this rear garnish, a colored coating layer is formed on the inner surface of the base material in a portion other than the pattern, so that the pattern is visible through the base material from the outer surface side of the rear garnish. In order to create such a pattern, prior to forming the colored coating layer,
A masking material is attached to the part of the base material that will become the pattern, and in this state, paint is applied to the inner surface of the base material and onto the masking material. When the masking material is peeled off after the paint has hardened, the desired colored paint layer and pattern are formed.

However, there is a problem in that the pasting work is troublesome. In addition, since the pattern cannot be made to appear after the rear garnish is assembled to the vehicle body, it is not suitable for high-mix, low-volume production in which many types of letters, designs, etc. are set, and there is also the problem of undesirable production management. there were.

Laser light is irradiated from the outer surface of the base material. This laser light passes through the base material and is irradiated onto the metal layer on the inner surface of the base material. As a result, the portion of the metal layer irradiated with the laser beam is heated and becomes a rough surface. This rough surface portion appears as a pattern from the outer surface of the base material.

り、これらは互いに接着固定されている。As shown in FIG. 1(c) and FIG. 2, the rear garnish 1 of this embodiment is formed into an oblong plate shape made of synthetic resin material so as to be installed between the left and right rear combination lamps 3 at the rear of the automobile 2. It is composed of a pair of base materials 4 and 5 and a metal layer 6 with a thickness of about 400 mm formed between the side base materials 4 and 5 (on the inner surface side of the outer base material 4). They are glued and fixed to each other.

ら視認できるようになっている。The synthetic resin material constituting the base materials 4 and 5 is PMMA.
(polymethyl methacrylate), PC (polycarbonate), and other transparent synthetic resins. Here, transparent includes not only colorless and transparent, but also colored transparent and translucent. Further, the metal layer 6 is formed by using a metal material such as aluminum or zinc and depositing atoms of the metal material on the inner surface of the base material by vacuum evaporation, sputtering, etc., and has some light transparency. There is. A portion of this metal layer 6 is roughened by irradiation with laser light, which will be described later, and the roughened portion is visible as various patterns 7 from the outer surface of the base material 4.

力が得られ、装置が小型である固体レーザ（Ｎｄ−ＹＡ
Ｇレーザ）を用いた。This method uses an optical system such as a lens to irradiate a highly parallel, high-power laser beam onto the surface of the workpiece in a converged state. In addition, this laser beam processing method can be narrowed down to a minute spot, making it easy to create a complex pattern 7;
In addition to being able to process in a non-contact state, it is also possible to process remote parts or at difficult angles using optical means, making it easy to automate. It has features such as being able to be processed. There are three types of lasers: gas lasers, liquid lasers, and solid-state lasers. In this example, a solid-state laser (Nd-YA
G laser) was used.
次に、前述したようなレーザ光を用いて模様７を現出す
る方法について第１図（ａ）〜（ｃ）に従って説明する
。Next, a method of creating the pattern 7 using the laser beam as described above will be explained with reference to FIGS. 1(a) to 1(c).

を有する金属層６となる。First, prior to this laser beam irradiation, a metal layer 6 made of aluminum is formed on the entire inner surface of the base material 4 by sputtering, as shown in FIG. 1(a). That is, aluminum is used as a cathode (Yuichiget), and a voltage of several hundred volts is applied between this cathode and anode in low-pressure argon gas. This causes a glow discharge, and aluminum atoms at the cathode are ejected by collisions with positive argon ions during the discharge. The atoms ejected by this sputtering form a film on the inner surface of the base material 4 attached to the anode, and this becomes a metal layer 6 with metallic luster.
そして、前記のように金属層６が形成された基材４に透

ーザ光りを照射する。Then, by adhering the transparent resin base material 5 to the base material 4 on which the metal layer 6 is formed as described above, the metal layer 6 is sandwiched between the pair of base materials 4 and 5, and then this is attached to the automobile 2. Attach it to the specified position at the rear. Next, as shown in Figure 1(b),
Set the Nd-YAG laser processing machine near the base materials 4 and 5, focus the laser beam on the part of the metal layer 6 where you want the pattern 7 to appear, and emit the laser beam with an output of 1 to 30 W/m. irradiate.
このようにレーザ光りが基材４に向けて照射されると、
この基材４が透明な合成樹脂により形成されているため
に、レーザ光りは基材４を透過して金属層６に照射され

部分の金属層６が、サンドペーパの表面のような微細な
起伏（表面粗さ）を有する粗面となる。このときの金属
層６における粗面部分が目的とする模様７となる。When the laser light is irradiated towards the base material 4 in this way,
Since the base material 4 is made of a transparent synthetic resin, the laser light passes through the base material 4 and is irradiated onto the metal layer 6. When the metal layer 6 is irradiated with laser light, the temperature of the irradiated area of the metal layer 6 is increased in a very short time. As a result, as shown in FIG. 1(c), the portion of the metal layer 6 irradiated with the laser beam becomes a rough surface having minute undulations (surface roughness) like the surface of sandpaper. The rough surface portion of the metal layer 6 at this time becomes the desired pattern 7.

で、リヤガーニッシュｌ全体として、アクセントのある
２種の金属面と高級感に富む美しい外観が得られる。In the case where the pattern 7 appears as described above, or in the case of a tea bag L, when light hits a portion of the metal layer 6 other than the pattern 7 during the daytime, it is strongly reflected at a certain reflection angle, so that it has a rich metallic luster. In addition, pattern 7 has a unique rough surface with fine undulations (surface roughness) and a color and reflectance unique to metals, and when light hits this, it reflects strongly and diffusely, giving it a slightly whitish metallic color. As a result, a beautiful exterior with a metallic and thick feel can be obtained. Then, the pattern 7 in the metal layer 6
and the other parts have a synergistic effect that emphasizes and stands out the contrasting appearances of each of the above, so the rear garnish l as a whole has two types of metal surfaces with accents and a rich sense of luxury. A beautiful appearance can be obtained.
さらに、自動車２後部のランプが点灯される夜間には、

車後方からは金属調の模様７が浮き上がったように見え
る。Furthermore, at night when the lights on the rear of the car 2 are lit,
Since the base material 5 is made of transparent resin and the metal layer 6 has some light transmittance, the light from the lamp is transmitted through the base material 5.
The light is irradiated onto the inner surface of the metal layer 6 through the rays. Therefore, the metallic pattern 7 appears to be floating from the rear of the car.
また、前述した金属層６は基材４を介して見ることにな

できる。Moreover, since the metal layer 6 mentioned above is seen through the base material 4, it can be visually recognized as a beautiful appearance with a rich sense of depth. Furthermore, since the metal layer 6 is sandwiched between the pair of base materials 4.degree. 5, good weather resistance and durability can be maintained.

The pattern 7 can be accurately formed into a predetermined shape by this simple process. In addition, the pattern 7 can be formed while the pair of base materials 4 and 5 sandwiching the metal layer 6 remain attached to the rear of the automobile 2, and furthermore, multiple types of patterns can be formed by simply changing the irradiation area of the laser beam. It is possible to form logos, grade names, patterns, etc. Therefore, it can easily handle high-mix, low-volume production, which is also preferable from the point of view of production control. Furthermore, original characters, patterns, etc. can be created very easily according to demand.
