CITATION LIST Patent Literature 1: Japanese Laid-Open Patent Publication No. Hei No. 7-216116. SUMMARY OF THE INVENTION Problems to be Solved by the Invention However, the above-described method produces a thickness portion of the coating film 102 at the boundary between the portion where the coating film 1 2 is removed and the portion where the unremoved portion is removed. Drop. That is, a recess in which the thickness portion of the coating film 102 is removed is generated. As a result, when the button formed by the button is used for a long period of time, the color of the resin molded article 101 of the underlayer is deteriorated due to accumulation of contaminants such as scales in the concave portion, and the display becomes unclear. I This step causes problems such as peeling of the coating film around the recess. 3 201016370 An object of the present invention is to provide a method for producing a laser etched article which can solve the above problem by irradiating the concave portion with laser light and maintaining the sharp display f of the coating film portion without peeling off. Means for Solving the Problems The present invention has the following features in order to achieve the above (four)'.

As the wax layer, for example, the wax is formed by laminating the decorative layer of the resin layer by transfer and transfer of the film in the above invention. Further, the above invention may be the same surface. It is in the same range. Wherein, the surface of the foam layer and the surface of the decorative layer but the surface of the decorative layer is ±0. 3 rom level difference surface of the foam layer may be higher than the surface of the decorative layer, in the above invention The laser etched article of the present invention described in the item is characterized by the method for producing any of the above-described laser money carvings. According to the invention, the method of manufacturing the laser etched article of the present invention, after irradiating the laser beam and removing the decorative layer, removes the decorative layer or irradiates the laser beam 201016370 to foam the surface of the resin layer. By this foaming, the resin layer expands to fill the recesses derived from the portion from which the decorative layer is removed. Since the area irradiated by the laser light does not generate the above-mentioned concave portion, the area can maintain a vivid display. Also, there is no need to worry that the above-mentioned stepped portion of the portion where the decorative layer is removed and the portion which is not removed causes the decorative layer to peel off. X, by the above invention, a decorative layer can be formed by transferring a transfer layer of a film. Therefore, it is also possible to form the decorative layer simply. ❹ X, by the above invention, the surface of the foamed layer can be on the same side as the surface of the decorative layer. Therefore, a laser etched article having a smooth surface can be obtained. Further, by the above invention, the surface of the foamed layer can be made higher than the surface of the decorative finish. Therefore, the 'foam layer can make the braille used by people for visual impairment.

Fig. 3 is a cross-sectional view showing a method of providing a decorative layer on the surface of a resin molded article by a transfer method. Fig. 4 is a cross-sectional view showing a method of forming a decorative layer on the surface of a resin molded article by a transfer method. Fig. 5 is a cross-sectional view showing an example of a laser etched article formed by the method for producing a laser-engraved article of the present invention. Figure 6 is a cross-sectional view showing a laser etched article formed by a conventional method of manufacturing a laser etchant. An example of a resin molded article of a resin layer! It is a resin composition which causes foaming by laser irradiation. The resin molded article may contain, in addition to the resin composition 5 201016370, an additive which foams the resin composition by laser light and/or an additive which promotes foaming.

Among them, semiconductor lasers such as a wavelength of (10) μ:·laser 824 nm AlGaAs laser are common and easy to use. , such as the Ua), the fine-formed -1 to the decorative molding 6 with the decorative layer 2, and the laser light 2 is applied from the side of the coating layer 2 6 - gossip. A method of illuminating the laser beam 3 to form an arbitrary character and pattern. A usable example ^ 1 j. For example, a method of moving the decorative article 6 immediately after the solid-state laser beam 3 is applied, and the molded article 6 is moved left and right to the left and right to move the laser light 11 201016370 method. When the laser light 3 is irradiated as shown in FIG. 1(b), the decorative layer 2 irradiated with the laser light 3 is removed by the energy of the laser light 3, and after the decorative layer is removed or the laser light is irradiated. While the decorative layer is removed, the irradiated portion of the resin molded article 1 is also melted and dissolved. At this stage, the irradiation area
域的加飾$ 2的厚度部分的凹部會產生。再繼續雷射光之 照射’樹脂成形品1的照射部分的最表面部分會被燒盡， 樹脂成形A 1的照射部内部中溶解樹脂中所含之樹脂中所 含的低分子量樹脂成分、分解生成物、添加劑等的揮發成 分在南溫被熱氣化’或發泡，藉此樹脂成形品i的照射部 分增高，成為發泡層4。如第1(C)圖所示，藉由調節雷射 光3的照射時間、照射強度等，可使加飾；I 2與發泡層4 的最高位置大致相同而不會在兩者之間產生段差。在該發 泡層4的表面不會有指垢等汙潰堆積而不損及發泡層4的 顯色而維持鮮明的顯示，兩者的邊界部分亦不會有加御層 2的剝洛。在此狀態中雷射光3照射停止時，發泡層4在 内部含有多數的泡的狀態被冷卻固化，而形成雷射蝕刻品 5。該發泡層4有時與原本的樹脂成形品1顏色相異，多半 疋因光亂反射而呈現乳白色。再者，實際上從雷射光3的 …、射到發泡層4的形成為止的步驟是在極短時間内發生。 又，藉由調節雷射光的照射3時間和強度，發泡層4 的表面可比加饰層2之表面更高(參照第5圖）。此時，發 /包層4可使用於視覺障礙的人使用的點字。為使點字可以 易於手指觸覺讀取，發泡層“匕加飾層2表面隆起的高度 勺〇.4 〇.7mm(較佳為〇5〇6nim)為較佳。再者，雷射光3 12 201016370 的照射超過時，發泡層4會燒盡，而產生凹部於雷射钱刻 品5。 實施例1 以厚度38 A®之聚乙烯對笨二曱酯薄膜為基體薄片 12，接著依序以凹版印刷法形成剝離層13，圖案層，接 著層15，而得到轉印薄片1^剥離層13，圖案層14，分 別使用丙烯酸系樹脂組成之顏料而形成。又，接著層Η則 φ 使用氯化乙烯_醋酸乙烯共聚合體系樹脂組成之顏料而形 成的。 Π配置於成形用模型 接著，將上述製得之轉印薄片 31之間，模型關閉之後，射出成形樹脂32而一體化，打 開模型後，剝離轉印薄片n之基體薄片12而得到樹脂成 形品1上轉印g 16轉印作為加飾層2之加飾成形品6。A recess in the thickness portion of the field trimming $2 will be produced. Further, the irradiation of the laser light is continued, and the outermost surface portion of the irradiated portion of the resin molded article 1 is burned out, and the low molecular weight resin component contained in the resin contained in the resin is dissolved in the inside of the irradiated portion of the resin molded A1 to be decomposed. The volatile component such as a substance or an additive is heated and vaporized at the south temperature or foamed, whereby the irradiated portion of the resin molded article i is increased to become the foamed layer 4. As shown in Fig. 1(C), by adjusting the irradiation time, the irradiation intensity, and the like of the laser light 3, the decoration can be made; I 2 is substantially the same as the highest position of the foamed layer 4 without being generated between the two. The difference is the segment. On the surface of the foam layer 4, there is no stain deposit such as finger scale, and the coloration of the foam layer 4 is not damaged, and a clear display is maintained, and the boundary portion between the two layers does not have the peeling of the layer 2 . When the irradiation of the laser light 3 is stopped in this state, the foamed layer 4 is cooled and solidified in a state in which a large number of bubbles are contained therein, and a laser etched article 5 is formed. The foamed layer 4 may be different in color from the original resin molded article 1, and most of the foamed layer 4 is milky white due to light reflection. Further, the steps from the laser light 3 to the formation of the foam layer 4 actually occur in a very short time. Further, by adjusting the irradiation time and intensity of the laser light, the surface of the foam layer 4 can be made higher than the surface of the decorative layer 2 (refer to Fig. 5). At this time, the hair/cladding layer 4 can be used for the braille used by the visually impaired person. In order to make the braille can be easily read by the finger, the foam layer "is preferably a height of 〇.7 mm (preferably 〇5〇6nim) of the surface of the decorative layer 2. Further, the laser light 3 12 When the irradiation of 201016370 is exceeded, the foamed layer 4 will burn out, and a concave portion will be produced in the laser-engraved article 5. Example 1 A polyethylene-p-benzoate film having a thickness of 38 A® is used as a base sheet 12, and then The release layer 13 and the pattern layer are formed by gravure printing, and the layer 15 is formed to obtain a transfer sheet 1 and a pattern layer 14 which are respectively formed using a pigment composed of an acrylic resin. It is formed by using a pigment of a resin composition of a vinyl chloride-vinyl acetate copolymerization system. The crucible is placed in a molding mold. Then, after the mold is closed between the transfer sheets 31 obtained as described above, the molding resin 32 is injected and integrated. After the mold is opened, the base sheet 12 of the transfer sheet n is peeled off to obtain a decorative molded article 6 as a decorative layer 2 on the resin molded article 1 by transfer g 16 .
