を載置して、透明樹脂を射出するという方法である。Conventionally, as a meter panel, displays and decorations such as letters and figures are formed on the front surface of the meter panel, which has irregularities formed on the surface of the cavity of an in-mold mold. There is a model with only the main parts of the house made transparent, and at night, by illuminating it from the back, only the main parts, such as the numerical scale of the speedometer, stand out clearly, and during the day, natural light from outside can be seen. There are meter panels that have text, graphics, and other displays and decorations that can be recognized. In addition, the manufacturing method involves placing a release layer on the base film, a light-colored colored layer that transmits light, and a cover to cover other than the main parts, in an in-mold mold with unevenness formed on the surface of the cavity. In this method, a transfer material on which a layer and an adhesive layer are sequentially formed is placed, and a transparent resin is injected.

る。However, while the main parts of the meter panel mentioned above become bright and transparent when the light rays pass through them, the parts other than the main parts of the meter panel are not light-transparent because they have a concealing layer that completely blocks the light rays. become a part. In the main parts, you can clearly see the state of the surface decoration, and even if the surface of the parts other than the main parts is decorated with matte or colored, there is no light passing through it, so there is no matte finish and the resulting brightness and darkness. The condition of the surface decorations, such as changes in color, was difficult to see clearly. In addition, since the main parts that are usually transparent are only the parts along the ring, such as the numerical scale of the speedometer, the area of the parts that are not transparent is proportionally large.
At night, when illuminated from the back, the entire panel was dark. In addition, in the conventional manufacturing method of meter panels, the surface only has irregularities due to so-called grains formed in the cavity part of the in-mold mold, so only monotonous irregularities can be formed, and the intensity of light scattering changes. There is no color, and all you can do is a monotonous matte finish. Therefore, the brightness on the meter panel surface,
It was not possible to obtain a design rich in changes in saturation. This invention solves the above-mentioned problems, and by making parts other than the main parts transparent, it is possible to determine the intensity of light scattering on the meter panel surface by the transmitted light from behind. The entire panel is bright even at night,
It is an object of the present invention to provide a meter panel and a method for manufacturing the same, which can provide two decorations with complex changes in brightness and saturation.

Transfer material 11 used in this meter panel manufacturing method
As shown in FIG. 3, a cape layer 2 is formed on a base film 1, and on top of that, a transfer layer is formed in which a release layer 3, a colored layer 4 that does not block light rays, and an adhesive Nj 5 are formed in this order. It is possible to form a matte pattern on the surface of an in-mold molded product, which is a transfer target. As the base film 1 of the transfer material 11, for example, a film used as a base film for ordinary transfer materials, such as a plastic film made of polyethylene terephthalate, polypropylene, polyethylene, nylon, or cellophane, or a composite film of these and paper, is used. . On this base film l, a matte fine unevenness 1
A cloak layer 2 of 4 is provided. Specifically, for example, it is coated with a resin layer containing fine powder of silica, calcium carbonate, polyethylene wax, glass beads, etc., with a fine particle size, by a printing method or the like. In this case, the resin layer may include curable resins such as urethane, melamine, and epoxy in addition to plastic resins.
UV or electron beam curable resins such as methyl methacrylate may also be used. In addition to being provided on the entire surface of the base film 1, the cloak layer 2 may be formed by partially changing the strength of the cloak feeling as necessary. Furthermore, instead of providing the mantle layer 2, a material into which fine powder such as an extender pigment is kneaded may be used as the base film 1 during the formation of the base film 1 described above. Alternatively, the base film 1 may be a plastic film whose surface is provided with fine irregularities 14 by physical means such as sandblasting or chemical etching. In addition to providing the unevenness 14 on the entire surface of the base film 1, the unevenness 14 may be formed by partially changing the strength of the cloak feeling as necessary. In addition, matte and glossy parts may be expressed by combining them with designs such as patterns and the shape of the molded product.In some cases, the release process may be applied to the base film 1 at the same time. Good too. The release layer 3 is provided on the entire surface of the mantle layer 2, and is peeled off from the mantle layer 2 after transfer, and the base film 1 and the base film 1 are formed on the surface of the release layer 3 corresponding to the unevenness formed on the surface of the matte layer 2. In this case, a reverse pattern of concavities and convexities 14 is formed. Also,
Since it becomes the surface of the object to be transferred after transfer, it also has the function of protecting the transfer layer 7. The release layer 3 is formed on the base film 1 by a normal printing method such as a roll coating method, a gravure printing method, or a screen printing method. As the release layer 3, thermosetting resins such as acrylic resins and vinyl resins can be used. Furthermore, in order to sufficiently fulfill the role of a protective layer, thermosetting resins such as urethane resins and epoxy resins, and ultraviolet or electron beam curing resins such as methyl methacrylate may be used. The colored layer 4, which does not block light rays, is formed not only on important parts such as the scale of the speedometer but also on the entire surface using colored ink that transmits light. In this way, light can pass through parts other than the main parts. As the colored layer 4, it is preferable to use a commonly used printing ink in which pigments, dyes, etc. are dispersed or dissolved in an organic binder. Furthermore, for example, when a part that does not require bright display at night is required, colored ink can be selected so that only that part becomes a concealing part. In this case as well, it is necessary to prevent the image from becoming dark as a whole due to the presence of the concealing portion. The adhesive N5 is for fixing the transfer layer 7 of the transfer material to the object to be transferred. As the adhesive layer 5, a heat-sensitive or pressure-sensitive resin suitable for the material of the plastic molded article to be transferred is appropriately used. For example, if the material to be transferred is an AS resin, an acrylic resin or a vinyl resin may be used, and if the material is polypropylene, a chlorinated polypropylene resin or an ethylene-vinyl acetate copolymer resin may be used. Also, if necessary, between the colored Jii4 and the adhesive N5,
Half sowing layer 6 is provided entirely or partially. The half-deposited layer 6 has the contradictory functions of transmitting the illumination from the back of the meter panel to the surface and reflecting and scattering the illumination from the outside. The half-evaporated layer 6 is made of metal such as aluminum, chromium, nickel, etc.
It is preferable to provide the film by vacuum evaporation, ion blating, sputtering, or the like. The film thickness varies depending on the type of metal used, but in the case of aluminum, the film thickness falls within the range of 50 to 400. If it is thinner than 50 people, the reflection and scattering of light will not be sufficient when the inside of the meter panel is darkened. On the other hand, if there are more than 400 people, even if the inside of the meter panel is made brighter, the light will not be able to pass through sufficiently. However, it goes without saying that it is affected by the brightness of the lighting provided inside the meter panel. This half-deposited layer 6 may be partially provided by an appropriate method if necessary, and if necessary, a pre-deposited layer may be provided between the release layer 3 and the half-deposited layer 6 to improve suitability for metal plate deposition. An anchor layer may also be provided. In this case, if the layer forming the unevenness 4 is provided below the front anchor layer, a less matting effect can be obtained. Also, if necessary, between the half-deposited layer 6 and the adhesive layer 5,
A rear anchor layer may be provided to increase the adhesion between the two. In addition, peeling layer 3, colored layer 4, half vapor deposition N7, adhesive layer 6
Also, it is preferable to select a material that has excellent adhesion properties at the mutual interface between the front anchor layer and the rear anchor layer. The in-mold molding die includes a movable die and a fixed die, and is configured so that the transfer material 11 can be fixed to the movable die side, and a cavity portion is formed by closing both the die. On the molding surface 12 in contact with the transfer material 11 of the cavity portion, irregularities 3 due to grains are formed on the surface of the in-mold molded product. These irregularities may be formed entirely or partially on the molding surface 12 of the cavity portion. The size of the unevenness 13 is made larger than the unevenness 14 formed by the mantle layer 2 of the transfer material 11. Since the resin of the molded product does not come into direct contact with the molding surface 12 of the cavity portion, but the transfer material 11 is sandwiched therein, if too fine irregularities are formed, the molded product cannot have an uneven surface. Simultaneous in-mold molding transfer is performed using the above-described transfer material 11 and a mold. First, transfer material 11 is placed in a predetermined position of the mold.
to be fixed. At this time, the transfer material 11 is positioned and fixed using a film feeding device having a positioning mechanism. Then, the mold is closed and resin is injected from an injection machine. After the resin has cooled, the mold is opened and the in-mold product is taken out. When the heath film 1 of the transfer material 11 is peeled off from the in-mold molded product, the degree of matteness differs partially, and this is an in-mold molded product that has a surface with varying brightness and saturation. is obtained. When positioning the transfer material 11, use a film feeding device having a positioning mechanism to position the transfer material 11 so that the uneven portions 14 of the transfer material 11 and the uneven portions 13 of the mold match and overlap. Further, finer unevenness 14 is formed by the transfer material 11 on the surface of the unevenness 13 formed by the mold of the in-mold molded product. Therefore, the unevenness expressed after molding is caused by the unevenness 14 of the mat layer 2.
A matte feeling with a slightly different degree of matteness can be obtained from a matte part due to a chisel or an uneven part due only to the unevenness 13 of the mold. The light-transmitting resin injected at this time is various plastic resins such as acrylic resin, styrene resin, vinyl resin, polycarbonate resin, and polyethylene terephthalate resin. 2. The transfer material is fixed in an in-mold mold that has been subjected to matte processing with a depth of approximately 2 to 50 μm. The transfer material has a thickness of 3
A cloak layer is formed on a base film made of 8 μm polyethylene terephthalate. The matte layer is formed by gravure printing so that the unevenness depth is about 0.1 to 2 μm. Furthermore, on top of that, a release layer and a colored layer consisting of the following composition,
A front anchor layer, a half vapor deposition layer, a rear anchor layer, and an adhesive layer are sequentially formed. Release layer (weight part) Acrylic
Vinyl resin 10 Toluene 45 Methyl ethyl ketone 45 Colored layer acrylic vinyl resin 20 Pigment 30 Toluene 15 Methyl ethyl ketone 25 Butyl acetate 10 Half-deposited layer aluminum Transmittance 35% Pre-anchor layer vinyl resin 20 Toluene 40 Ethyl acetate 40 Adhesive layer Vinyl chloride-vinyl acetate Copolymer toluene 45 methyl ethyl ketone 45 Then, in-mold molding was performed using an acrylic resin under the following conditions. The resulting molded product is illuminated from the back, making not only the important parts such as numbers shine brightly, but also the other parts, making the entire surface bright, and because the two types of unevenness of the mold and the matte layer are appropriately combined, it has a glossy finish. There are three erasing stages, and the design has changes in the brightness and saturation of the colors of transmitted light and reflected light.

易に製造できる。The meter panel of the present invention has irregularities even finer than the above-mentioned irregularities on the surface of a light-transmissive molded product having an irregular surface formed by an in-mold molding die with irregularities formed in the cavity part. A transfer layer is formed that has a cloak layer and a colored layer that does not block light rays. Therefore, since the transfer layer formed on the surface of the molded product does not block light rays, even at night when only the back side is illuminated, not only the main parts on the meter panel but also the entire design can be seen as being bright. In addition, since a transfer layer with finer unevenness is formed on the uneven surface of the molded product formed by the unevenness of the mold, it is possible to suitably combine rough and fine areas with different types of unevenness. A surface state rich in variation is formed. Therefore, it is possible to vary the intensity of the scattering of transmitted light and reflected light, resulting in a meter panel that can express a design with complex changes in brightness and chroma. Further, the method for manufacturing a meter panel of the present invention uses an in-mold molding die in which a cavity portion is formed with unevenness, and a transfer material having a mantle layer having finer unevenness than the above-mentioned unevenness. The instrument panel is obtained using the in-mold simultaneous transfer method. Therefore, meter panels having various degrees of unevenness on the surface can be easily manufactured.
