ある固体レーザのうちＮｄ−ＹＡＧレーザを用いた。This method uses optical means such as lenses to irradiate a highly parallel, high-power laser beam onto the surface of the workpiece in a converged state, making it suitable for material removal. There is. In addition, this laser beam processing method can be narrowed down to a minute spot, making it easy to create complex patterns4, and can be processed in a non-contact manner. It has the advantages of being easy to automate as it can process and process at difficult angles, and ■The force applied to the workpiece during processing is small, making it possible to process thin films. There are three types of lasers: gas lasers, liquid lasers, and solid-state lasers. In this example, a Nd-YAG laser was used among solid-state lasers that can provide high output and are compact in size.
次に、Ｎｄ−ＹＡＧレーザ光（以下、単にレーザ光とい

。まず、このレーザ光りの照射に先立ち、第１図（ａ）
に示すように、基材１上に金属光沢層２及び着色塗膜層
３を順に形成する。Next, a method of creating the pattern 4 using Nd-YAG laser light (hereinafter simply referred to as laser light) L will be explained. First, prior to irradiation with this laser light, as shown in Figure 1(a)
As shown in the figure, a metallic luster layer 2 and a colored coating layer 3 are formed in this order on a base material 1.
詳しくは、基材１を陰極とし、クロムイオンを含む電解
溶液中へこの基材１と陽極を浸漬する。そして、電解溶
液外部から基材１及び陽極に電圧を印加すると、基材１
表面にクロムめっきが析出して金属光沢層２が形成され

で焼き付は塗装すると、着色塗膜層３が形成される。Specifically, the base material 1 is used as a cathode, and the base material 1 and the anode are immersed in an electrolytic solution containing chromium ions. Then, when a voltage is applied to the base material 1 and the anode from outside the electrolytic solution, the base material 1
Chrome plating is deposited on the surface to form a metallic luster layer 2. Subsequently, a urethane paint is baked on the entire surface of the metallic gloss layer 2 at a low temperature to form a colored coating layer 3.
続いて、前記のように金属光沢層２及び着色塗膜層３が
積層された基材１をＮｄ−ＹＡＧレーザ加工機にセット

になる。Subsequently, the base material 1 on which the metallic luster layer 2 and the colored coating layer 3 are laminated as described above is set in an Nd-YAG laser processing machine. Then, as shown in FIG. 1(b), the laser beam is focused on the part of the colored coating layer 3 where the pattern 4 is desired to appear, and the laser beam is emitted from the irradiation part 5 at an output of 1 to 30 W/m. irradiate. In this way, the temperature of the colored coating layer 3 at the irradiated area reaches its own evaporation temperature in a very short time, and it is vaporized and removed from the surface layer. Therefore, as shown in FIG. 1(c), the metallic luster layer 2 in the area where the colored coating layer 3 has been removed is exposed from the other colored coating layer 3.
ところで、本実施例ではクロムめっきにより金属光沢層
２を形成したので、前記のように着色塗膜層３にレーザ
光りを照射した際に、その焦点が金属光沢層２に位置し
ていたとしても、レーザ光りは金属光沢層２表面で反射
されてしまう。そのため、この金属光沢層２がレーザ光
りによって除去されたり、悪影響を受けたりするおそれ
がない。By the way, in this example, the metallic luster layer 2 was formed by chromium plating, so when the colored coating layer 3 is irradiated with laser light as described above, even if the focal point is located on the metallic lustrous layer 2. , the laser beam is reflected by the surface of the metallic gloss layer 2. Therefore, there is no risk that this metallic luster layer 2 will be removed or adversely affected by laser light.
また、金属光沢層２がレーザ光りの照射によって除去さ
れる材質である場合には、レーザ光りの焦点位置を正確
に設定する必要があるが、本実施例では前述したように
クロムめっきのような、光を反射する材料で金属光沢層
２を形成したので、前記レーザ光りの焦点位置をあまり
考慮しなくてもすむ。従って、レーザ光りの焦点位置の
正確な設定が不要となる分、模様４の現出作業が容易と
なる。In addition, if the metallic luster layer 2 is made of a material that can be removed by laser beam irradiation, it is necessary to accurately set the focal position of the laser beam, but in this example, as described above, a material such as chrome plating is used. Since the metallic luster layer 2 is formed of a material that reflects light, there is no need to take much consideration to the focal position of the laser beam. Therefore, since it is not necessary to accurately set the focal position of the laser beam, the work of revealing the pattern 4 becomes easier.
前記のように着色塗膜層３から模様４が現出されたら、
その着色塗膜層３表面及び模様４部分にウレタン系二液
型クリヤ塗料を焼き付は塗装する。When the pattern 4 appears from the colored coating layer 3 as described above,
A urethane-based two-component clear paint is baked onto the surface of the colored coating layer 3 and the pattern 4.
すると、無色透明のトップコート層６が形成される。Then, a colorless and transparent top coat layer 6 is formed.
このようにして製造されたホイールカバーにおいては、
着色塗膜層３から金属光沢を有する模様４が現出し、こ
の模様４以外の着色塗膜層３が金属光輝状の模様４を強
調させるので、高級感に富む美しい外観が得られる。In the wheel cover manufactured in this way,
A pattern 4 with metallic luster emerges from the colored coating layer 3, and the colored coating layer 3 other than this pattern 4 emphasizes the metallic glitter pattern 4, so that a beautiful appearance rich in luxury is obtained.
ところで、前記着色塗膜層３の一部を除去して模様４を
形成すると、両者の境界部分においては金属光沢層２に
対する着色塗膜層３の密着性が悪くなり剥がれやすくな

層３及び模様４上に透明なトップコート層６を形成した
ので、これにより着色塗膜層３が保護され、金属光沢層
２からの同着色塗膜層３の剥離が防止される。By the way, when a part of the colored coating layer 3 is removed to form the pattern 4, the adhesion of the colored coating layer 3 to the metallic luster layer 2 deteriorates at the boundary between the two, making it easy to peel off. However, as described above, in this example, the transparent top coat layer 6 was formed on the colored coating layer 3 and the pattern 4, so that the colored coating layer 3 was protected and the same from the metallic gloss layer 2 was formed. Peeling of the colored coating layer 3 is prevented.

、絵柄等も容易に加工することが可能である。As described above, according to the method of producing the pattern 4 of this embodiment, it is not necessary to provide the protrusions 22 in the prior art, and therefore,
Various patterns 4 having a metallic luster and emerging from a colored coating layer 3 can be produced in a simple process and at low cost without using nests or separate members. In addition, if you prepare a large number of base materials laminated with metallic luster layer 2 and colored coating layer 3, you can create multiple types of logos, grade names, designs, etc. by simply changing the shape of the part to be irradiated with laser light. This makes it easy to handle high-mix, low-volume production, which is also favorable in terms of production control. Furthermore, original characters, patterns, etc. can be easily processed according to demand.
