542777 A7 ———---- ~ ______ 5. Description of the invention (9) ~ '-22, 23 with adhesive layer (refer to Figure 2). (Please read the precautions on the back before filling this page) The first base layer 21 is transparent or translucent, and it also becomes the overall support for the el light-emitting decorative sheet 5. The first base layer 21 can be made of polycarbonate resin, polyurethane resin, polyimide resin, acrylic resin, acrylic resin, thin resin, polyurethane resin, and polycarbonate polybutene. A single-layer film made of a terephthalic acid alloy resin or the like is used as it. As X, a laminated film or a copolymerized film made of two or more selected resins may be used. The thickness of the first base layer 21 is preferably 50 to 250 μm. If it is less than 50 μm, it may fail to follow the extension during pre-forming, and there is a high risk of cracking at a portion where the thin portion is formed by a large amount of extension. In addition, if it exceeds 25 μm, it takes a long time to heat it to the optimal state during pre-forming, which results in poor production efficiency. Furthermore, even if the function of the first base layer 21 as a finished surface protection layer 47 is considered, the thickness exceeding 250 µm is unnecessary and the cost is increased. The decorative layer 22 is formed by appropriately combining a light-shielding coloring layer and a light-transmitting coloring layer and decorating them in an arbitrary pattern, and simultaneously transmitting light from the EL layer 49 in an arbitrary pattern when the EL layer 49 emits light. The light-shielding colored layer is a layer for shielding light from a light source, and is a layer which is partially superimposed to display a light-shielding pattern. As the material of the light-shielding colored layer, a thermoplastic resin, a thermosetting adhesive, and an ultraviolet-curable resin can be used as an adhesive, and a coloring ink containing a pigment or a dye with an appropriate color as a colorant can be used. The method of forming the light-shielding colored layer includes offset printing, gravure printing, and stencil printing. The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) -12-542777 A7 B7 V. Description of the invention (10) 4 Printing method. The film thickness of the light-shielding colored layer is preferably 30 to 30 μm. When the film thickness is less than 3.0 µm, sufficient light-shielding properties cannot be ensured in the place where the thin-layer portion is formed by stretching during pre-forming. In addition, if the film thickness exceeds 30 µm, the film thickness is disturbed during pre-forming, and the complete shape such as the edge portion cannot be reproduced. Further, the residual solvent is not easily volatilized ', which results in poor releasability during pre-molding or easy flow of the light-shielding colored layer when molten resin is injected. The light-transmitting colored layer is a layer that is fully or partially superimposed, and where the light-shielding colored layer does not exist, it is a layer that expresses a light-transmitting pattern such as colored characters or symbols. The light-transmitting colored layer can be the same as the light-shielding colored layer, except that it is light-transmissive. The thickness of the light-transmitting colored layer is preferably 3.0 to 30 μm. When the thickness of the light-transmitting colored layer is less than 3.0 μm, the light-transmissive colored layer cannot be melted against the heat during injection molding of the high-temperature molten resin, resulting in poor appearance. When it exceeds 30 μm, the total light transmittance of the light-transmitting colored layer itself is reduced, making it difficult for light from a light source to pass through, and it is difficult to recognize characters or symbols. When the translucent colored layer of the decorative sheet 2 is composed of a translucent colored layer and an adhesive laminated portion, it can achieve a visible light transmittance of 20 to 99%. It is also possible to mix and tint a color paint or a coloring dye to a transparent resin ink to achieve the aforementioned range. In addition, when the translucent colored layer of the decorative sheet 2 is composed of the base layer 21, the decorative layer 22, and the adhesive laminated portion, 'the visible light transmittance of 20 to 99% can be achieved. ) A4 size (210X297) (Please read the precautions on the back before filling this page)

Therefore, in this case, a transparent or translucent one of the second base layer 41 is used. If necessary, an adhesive layer 42 may be formed on the second base layer 41. The adhesive layer 42 is a layer provided to prevent the second base layer 41 from being affected by the solvent component when the el layer 49 is formed. The adhesive layer 42 may be composed of at least one single layer selected from any one of a thermoplastic resin, a thermosetting adhesive, or an ultraviolet curable resin, or a plurality of layers composed of any one of them. The adhesive layer 42 may be formed by a printing method or a coating method. The back electrode layer 43 constitutes one layer of the EL layer 49, and may be a conductive ink layer or the like formed by a printing method or a coating method. Furthermore, it is particularly preferable to use a black material such as carbon in order to prevent EL light leakage from the back surface of the decorative molded product.

The formed conductive film, or an organic transparent conductive film. A protective layer 47 may be provided as needed. The protective layer 47 is a layer for preventing a current from leaking from the transparent electrode layer 46 to the outside. It also has the effect of blocking the influence of the adhesive component of the adhesive sheet superimposed on the EL layer 49. The protective layer 47 can be selected from a thermoplastic resin, a thermosetting adhesive, or an ultraviolet curing resin and used as it. For forming the protective layer 47, a printing method or a coating method can be used. If necessary, an adhesive layer 48 may be formed on the inner surface of the second base layer 41 or on the protective layer 47. The adhesive layer 48 of the EL sheet 4 is a layer provided to adhere the L sheet 4 to a molding resin. The adhesive layer 48 can be the same as the adhesive layer 23 of the decorative sheet 2. The adhesive layer 48 may be opaque. Since the EL sheet 4 having such a structure is sufficient to be located only on the inner surface where the decorative sheet 2 is intended to emit light, the area of the EL sheet 4 is generally smaller than that of the decorative sheet 2. In addition, when the EL light-emitting decorative sheet 5 is made into a three-dimensional shape consistent with the surface shape of the ideal EL light-emitting decorative molded product 1, as long as the EL sheet 4 has a shape without excessive deformation, the el layer 49 will not be damaged. , So it is ideal. The decorative sheet 2 and the EL layer 4 are integrated via an adhesive layer 3 having a visible light transmittance of 50 to 100%, a turbidity of 20% or less, and a thickness of 10 to 150 μm (see FIG. 4). By using the adhesive layer 3 with a visible light transmittance of 50 to 100%, a turbidity of 20% or less, and a thickness of 10 to 150 μm, and through the decorative sheet 2, the paper standard can be fully issued to comply with Chinese National Standards (CNS) Α4 specifications ( 210X297 mm) -20- (Please read the notes on the back before filling this page)

Description of the invention (26) (Please read the precautions on the back before filling this page) Figure 30 is the inner view of the opening of the el-emission decorative sheet shaped into a bowl. Figure 31 also shows the opening of the EL light-emitting decorative sheet pre-shaped into a bowl shape. The first figure is a bottom view of the second figure. Since the EL sheet 4B is superimposed on the inner surface of the decorative sheet 2B, the el sheet 4b is a view of the perspective view of the decorative sheet 2B. FIG. 33 is a right side view of FIG. 31. Since the EL sheet 4B is superimposed on the inner surface of the add-on sheet 2b, the pull sheet 4B is a view of the perspective view of the decorative sheet 28. As shown in FIG. 35, the Among the constituent elements of the EL light-emitting decorative molded product shown in FIG. 3, an adhesive layer 42 is not provided, and a transparent electrode layer 46, a light-emitting layer 45, an insulating layer material, and a back electrode are sequentially arranged under the second base layer M. The layer 43, the protective layer 47, and the adhesive layer 48 can also be provided with an adhesive layer 3 on the second base layer, and at the same time, a molding resin 6 can be disposed under and around the adhesive layer *. In this case, a commercially available ITO film having a transparent electrode layer formed on a substrate film such as a ρEτ (polyethylene terephthalate) film can be used, and as long as the ITO film is sequentially printed by stencil printing, etc. The light emitting layer 45, the insulating layer 44, the back electrode layer 43, the protective layer 0, and the adhesive layer are formed by stacking, so that the EL sheet can be simply formed, and the mass productivity of the EL sheet can be improved. Furthermore, by appropriately combining any of the aforementioned various embodiments, the respective effects can be exerted. Since the present invention is constituted by the aforementioned structure, it has the following effects. The EL light-emitting decorative molded product of the present invention is formed by sequentially stacking an EL sheet, an adhesive layer, and a decorative sheet on a resin molded product. The El sheet is formed by forming at least an EL layer on a second base layer. The description of the adhesive layer is applicable to the Chinese paper standard (CNS) A4 (210X297) for this paper size 29 542777

Description of the invention Those who see a light transmittance of 50 to 100%, a turbidity of 20% or less, and a thickness of 10 to 15 μm, and the decoration sheet just mentioned is formed on at least a decoration layer on a transparent or translucent first substrate layer. Therefore, because the decorative sheet and the EL sheet are stacked with the adhesive layer interposed therebetween, even if the decorative sheet has a three-dimensional shape, the EL sheet is not easily affected by it and the light emitting function of the EL layer is not known, and El light emission can be performed reliably. . Further, the position variation of a part of the connection contact point of the EL layer forming the EL sheet is reduced, and the position accuracy can be ensured. In addition, the luminous decoration of the aforementioned structure is formed into a 幵 yu port, and since the transparent electrode layer of the EL sheet is not directly laminated on the decoration layer, excellent adhesion strength of the transparent electrode layer can be obtained. In addition, since the individual decorative pieces and the EL pieces are laminated and laminated with an adhesive therebetween, the decorative pieces and the EL pieces are less likely to cause defects, and are less prone to wear, which is very economical. In addition, the manufacturing method of the EL light-emitting decorative article of the present invention is to form an anal light-emitting decorative sheet having a three-dimensional shape in advance, and the aforementioned light-emitting decorative sheet is an EL sheet, an adhesive layer, and a decorative sheet. The EL sheet is formed by stacking in order, and the EL sheet is formed on the second substrate layer with at least an el layer, and the adhesive layer has a visible light transmittance of 50 to 100%, a turbidity of 20% or less, and a thickness of 10 to 150 μΓ. „, And the decoration sheet is a transparent or translucent substrate layer with at least a decoration layer formed. Next, the el light emitting film is set in a mold, and a molten resin is injected into the mold. By integrating the EL light-emitting decorative sheet and the molten resin, the EL light-emitting decorative molded product can be easily obtained. In addition, when the EL light is emitted, generally, an AC waveform of 50 V to 200 V and 20 KHz to 1 KHz is applied. .Because of the AC waveform with a high number of vibrations, this paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) (Please read the precautions on the back before filling this page)

-30- MZ // 7 V. Explanation of the invention (28 Therefore, the EL vibrates, and there is a possibility of generating acoustic noise. According to the structure of the fourth aspect of the present invention, since the EL is used for decorative films and molding resin-body molding Therefore, there is an effect that EL does not vibrate and does not generate audible vocalizations. In addition, EL is caused by moisture in the air invading the El light-emitting layer and its brightness is reduced. If the structure according to the fourth aspect of the present invention is EL Because the decorative film is integrally formed with the molding resin, it can prevent the invasion of moisture and have a long life. In addition, for example, when the elongation of the decorative sheet exceeds 12%, it is suitable as the present invention. In the fifth aspect of the structure, the decoration sheet is formed into a three-dimensional shape in advance, and then it is adhered to the EL sheet through an adhesive layer to obtain a three-dimensional EL light-emitting decoration sheet. If the extension rate of the decoration sheet exceeds At 120%, if the entire EL light-emitting decoration sheet is pre-formed, it will be difficult to determine the position of the decoration layer, which will reduce the position accuracy and increase the loss rate. In the foregoing case, when the entire EL light-emitting decoration sheet is pre-formed, Because the back electrode layer of the EL sheet is insufficient Because of lack of wood, the EL sheet cannot follow the extension of the decorative sheet and increase the danger of major defects such as burnout. This problem can be solved according to the fifth aspect. The EL light-emitting decorative sheet of the present invention, It is a transparent or translucent first substrate layer with at least a decorative layer formed on the decorative sheet, and an EL layer formed on the second substrate layer with at least an EL layer, visible light transmission rate of 50 to 100% The adhesive layer with a turbidity of 20% or less and a thickness of 10 to 15 μm is integrated. Therefore, the EL light-emitting decorative sheet of the aforementioned structure does not directly stack the transparent electrode layer of the EL sheet on the decorative layer. Therefore, excellent adhesion strength of the transparent electrode layer can be obtained. In addition, the size of the decorative sheet and the sheet stack is adapted to the Chinese National Standard (CNS) A4 specification (210X297 public copy) due to the adhesive layer.
