In addition to forming a coating layer having a color different from that of the surface, only the coating layer covering the three-dimensional decoration portion is removed by a laser, and the entire surface of the interior material on which the three-dimensional decoration portion is formed is formed. Realized by forming a coating layer of irreversible material that becomes a discoloration part of a different color from other parts only at the part where energy is applied, and by applying energy to only the coating layer covering the three-dimensional decoration part by laser did. Embodiments of the present invention will be described below with reference to the drawings.

図1〜図5は、本発明の第1実施例を示す図である。車両用の内装材であるインストルメントパネル1は、芯材、パッド材、表皮材等の多層構造となっており、その表面2は樹脂で形成されている。インストルメントパネル1の表面2には、外観品質を高めるために立体加飾部3が一体的に形成されている。立体加飾部3は連続したステッチ模様を呈した形状で、その部分だけ表面2から隆起している。   1 to 5 are views showing a first embodiment of the present invention. An instrument panel 1 that is an interior material for a vehicle has a multilayer structure such as a core material, a pad material, and a skin material, and a surface 2 thereof is formed of a resin. A three-dimensional decoration portion 3 is integrally formed on the surface 2 of the instrument panel 1 in order to improve the appearance quality. The three-dimensional decoration portion 3 has a shape having a continuous stitch pattern, and only that portion protrudes from the surface 2.

インストルメントパネル1の表面2には、立体加飾部3も含んだ状態で、全面に塗膜層4が形成されている。塗膜層4は、インストルメントパネル1の表面2の色とは異なる色を有している。   On the surface 2 of the instrument panel 1, a coating layer 4 is formed on the entire surface including the three-dimensional decoration 3. The coating layer 4 has a color different from the color of the surface 2 of the instrument panel 1.

そして、インストルメントパネル1の表面2に形成された塗膜層4のうち、立体加飾部3を覆っている部分だけを、レーザーLにより除去する。そうすると、立体加飾部3の部分だけ、塗膜層4とは異なる表面2の色が露出する。   And only the part which has covered the solid decoration part 3 among the coating-film layers 4 formed in the surface 2 of the instrument panel 1 is removed by the laser L. FIG. If it does so, only the part of the three-dimensional decoration part 3 will expose the color of the surface 2 different from the coating-film layer 4. FIG.

次に、塗膜層4が除去されて露出した立体加飾部3の表面に、更にレーザーLにより、微細凹凸としての縒目状溝5を形成する。   Next, a grid-like groove 5 as fine irregularities is further formed by a laser L on the surface of the three-dimensional decoration portion 3 exposed by removing the coating film layer 4.

以上説明したように、この実施例によれば、立体加飾部3の塗膜層4だけをレーザーLにより除去するため、立体加飾部3はインストルメントパネル1の表面2の色が露出し、塗膜層4で覆われている他の一般面とは色調が異なることになる。従って、ステッチ模様の立体加飾部3が目立ち、インストルメントパネル1の外観品質が向上する。   As described above, according to this embodiment, since only the coating layer 4 of the three-dimensional decoration unit 3 is removed by the laser L, the three-dimensional decoration unit 3 exposes the color of the surface 2 of the instrument panel 1. The color tone is different from those of other general surfaces covered with the coating layer 4. Therefore, the three-dimensional decoration part 3 of the stitch pattern is conspicuous, and the appearance quality of the instrument panel 1 is improved.

また、塗膜層4が除去された立体加飾部3の表面に、更にレーザーLにより縒目状溝5を形成したため、光沢及び触感も、他の一般面とは異なり、外観品質がより向上する。表面2の硬度を、塗膜層4よりも低くしておけば、露出した立体加飾部3が柔らかくなり、触感が更に向上する。   Further, since the grid-like grooves 5 are further formed by the laser L on the surface of the three-dimensional decoration part 3 from which the coating film layer 4 has been removed, the appearance quality is further improved, unlike the other general surfaces. To do. If the hardness of the surface 2 is made lower than that of the coating layer 4, the exposed three-dimensional decoration portion 3 becomes soft and the tactile sensation is further improved.

立体加飾部3にステッチ模様を想像させる縒目状溝5を形成したため、視覚の面で糸で縫製したのと錯覚しやすくなり、立体加飾部3の擬似加飾としての意匠性が向上する。   Since the grid-like groove 5 that makes the three-dimensional decoration part 3 imagine a stitch pattern is formed, it becomes easy to make an illusion of sewing with a thread in terms of vision, and the design as a pseudo decoration of the three-dimensional decoration part 3 is improved. To do.

図6は、本発明の第2実施例を示す図である。この実施例に係るインストルメントパネル6では、塗膜層4を除去した立体加飾部3の表面に、微細凹凸としての円形凹部8を多数形成した。従って、立体加飾部3に毛羽立ち感を与えることができ、立体加飾部3の擬似加飾としての意匠性が向上する。   FIG. 6 is a diagram showing a second embodiment of the present invention. In the instrument panel 6 according to this example, a large number of circular concave portions 8 as fine irregularities were formed on the surface of the three-dimensional decoration portion 3 from which the coating film layer 4 was removed. Therefore, a feeling of fluff can be given to the three-dimensional decoration unit 3, and the design as a pseudo decoration of the three-dimensional decoration unit 3 is improved.

図7及び図8は、本発明の第3実施例を示す図である。この実施例に係るインストルメントパネル9において、最初に立体加飾部3を含む表面10全体に塗膜層11が形成されるが、この塗膜層11は先の実施例とは種類が異なる。すなわち、この塗膜層11はレーザーLによるエネルギーを受けると、受けた部分だけが他の色に変色して変色部11aとなる性質を有している。いったん変色した変色部11aが元の色に戻らないように、塗膜層11は不可逆性素材で形成されている。   7 and 8 are views showing a third embodiment of the present invention. In the instrument panel 9 according to this embodiment, the coating layer 11 is first formed on the entire surface 10 including the three-dimensional decoration portion 3, but the type of the coating layer 11 is different from the previous embodiment. That is, when the coating layer 11 receives the energy from the laser L, only the received portion is discolored to another color and becomes a discolored portion 11a. The coating layer 11 is formed of an irreversible material so that the discolored portion 11a once discolored does not return to the original color.

従って、この塗膜層11をインストルメントパネル9の表面10全体に形成した後、立体加飾部3を覆っている部分だけにレーザーLを照射してエネルギーを加えと、立体加飾部3を覆っている部分だけが、他の塗膜層11とは異なる色の変色部11aになる。従って、ステッチ模様の立体加飾部3が目立ち、インストルメントパネル9の外観品質が向上する。   Therefore, after this coating layer 11 is formed on the entire surface 10 of the instrument panel 9, only the portion covering the three-dimensional decoration 3 is irradiated with laser L to add energy, and the three-dimensional decoration 3 is formed. Only the covered portion becomes a discoloration portion 11 a having a color different from that of the other coating layer 11. Therefore, the three-dimensional decoration part 3 of the stitch pattern is conspicuous, and the appearance quality of the instrument panel 9 is improved.

以上の実施例では、立体加飾部3としてステッチ模様を例にしたが、これに限定されず、その他の加飾形状であっても良い。また、内装材としても、インストルメントパネル1、6、9に限定されず、その他のものであっても良い。   In the above embodiment, the stitch pattern is taken as an example of the three-dimensional decoration unit 3, but the present invention is not limited to this, and other decoration shapes may be used. Moreover, as an interior material, it is not limited to the instrument panels 1, 6, and 9, and other things may be sufficient.
