In the present invention, the heat/pressure molding base V-) is mainly composed of an uncured thermosetting resin such as an unsaturated polyester resin and short fibers for reinforcement, and is further filled with as needed. It is formed into a sheet after being uniformly kneaded with agents, pigments, etc., and is typically used as a sheet molding compound (SMC) as a body material for automobiles and other electronic products. There are types of SMCs made by semi-curing thermosetting resins and thickening them with thickeners, but in either case, they are non-adhesive sheet materials that have latent thermosetting properties. However, it can be molded into any shape by heating and pressure molding, and after molding, the resin hardens and becomes a strong molded product.

By the way, since SMC contains a large amount of reinforcing short fibers as mentioned above, the short fibers are exposed on the surface of the molded product, and as it is, it cannot meet market demands in terms of aesthetic appearance. . Therefore, it is essential to apply a coating to hide the fiber skin after molding. There are also products in which pigments are blended into the SMC itself so that a molded product with a brighter color can be obtained, but in this case, the pigment f)E is uniformly dispersed throughout the SMC, so a large amount of pigment must be used. This will cause an increase in costs.

The present inventors focused on the above-mentioned circumstances, solved the above-mentioned drawbacks of SMC, and achieved a beautiful surface texture without impeding heat/pressure moldability and can be colored in any desired color at the same time as molding. We have been conducting research with the aim of developing sheet materials for various types of heat and pressure molding. As a result, if powder or granules based on unsaponified or semi-cured thermoplastic resin are attached to the surface of the base V-) for heating and pressure molding as described above, heating of the base sheet・During the pressure molding process, the powder is once melted and then hardened to form a hard surface film, making it possible to obtain a beautiful molded product with a smooth and smooth surface. We obtained the knowledge that it is possible to color the surface at the same time as molding by adding a pigment, and based on this knowledge, we filed a patent application. However, as a result of further experiments, it was found that depending on the application of the molded product, it was possible to sufficiently achieve the purpose even if thermoplastic resin, which was available at a relatively low V value, was used as powder for surface coating.

In the present invention, thermoplastic powder is adhered to a constant thickness on the surface of the conventional base sheet for heat and pressure molding (hereinafter simply referred to as base V-) as described above. ,
During the heating and pressure molding process, the powder material is once melted to form a liquid film on the surface of the molded product, but when it is cooled and removed from the mold, it solidifies to form a surface protective layer. Therefore, the fibrous skin on the surface of the base sheet is hidden by the holding layer formed by the powder, and a molded product with a smooth and beautiful surface can be obtained. If you use powder mixed with any pigment, you can color the surface of the molded product in the heated and pressurized bottom molding process. Since the pigment only needs to be blended into the powder or granules to be adhered, the noise generated when the pigment is used is also drastically reduced.

In addition, thermosetting resins include unsaturated polyester resin, ebony V resin, phenol resin, vinyleste V horse chestnut resin, polybutadiene resin, acrylic resin, polyurethane resin,
All conventionally known thermosetting resins can be used, including polyimide resin, melamine resin, polyacid anhydride-epoxy-styrene resin, and other similar resins, and can meet the required characteristics of the final molded product. The most suitable resin can be selected accordingly. For example, unsaturated polyester resin is used when excellent moldability is required, polyurethane resin is used when abrasion resistance is required, ebony V resin is used when corrosion and rust resistance is required, and heat resistance is required. is polyimide resin,
When weather resistance is required, acrylic resin is most suitable.3゜Furthermore, as a subcomponent to be blended with the above main component 4,
Hardening agents, stabilizers, fillers, colorants, thickeners, mold release agents, flame retardants, etc. are added in appropriate amounts as necessary. In addition, extremely effective subcomponents other than those mentioned above include hollow fine particles such as glass balloons, $/9X balloons, phenol resin balloons, and divinylbenzene-styrene copolymer balloons. That is, in addition to being effective as a filler, these hollow fine particles also enhance the heat insulation and soundproof properties of the base sheet, promote weight reduction, and, fourth, enhance moldability. These subcomponents are 5y ++ )
The fibers and the thermosetting resin may be kneaded together before being shaped into a sheet (or, as will be described later), the thermosetting resin may be dispersed and mixed into the sheet together with the fibers.

As the subcomponents used in combination as necessary, the subcomponents listed for the base sheet can be used in the same manner, but the fiber components are excluded. Therefore, the powder and granules are used to hide the fibrous skin on the surface (Base V-) to give a smooth and beautiful surface, and to color the surface of the molded product if necessary. It is necessary to actively exclude fibers that worsen reeds and surface skin. (w) Hollow fine particles that can be used in combination as a subcomponent can provide the above-mentioned effects (insulation, soundproofing, weight reduction, etc.) when combined into the base sheet (K), as well as the surface protective layer formed in the heat/pressure molding process. It is extremely effective because it has the effect of reducing the light transmittance of the color, increasing the hiding effect, and reducing the clarity of the coloring.

Although there is no particular restriction on the thickness of the powder or granules, the thickness should be at least 5 μm or more in order to reliably hide the fiber skin or obtain a clear colored state. On the other hand, there is no particular upper limit to the thickness, but once it exceeds 500 μm, it becomes V-)
In addition to some of the powder adhering to the surface falling off, the use of comparatively expensive powder and granule toilet spoons also increases, which is not economical.

In addition, the support film F' is effective in preventing the powder from falling off during storage or transportation. It is advantageous to use a thermoplastic resin film having the above-mentioned properties because it itself melts during the heating and molding process to form a surface coating layer. In the method described above, part of the powder is embedded in the resin R layer during the pressure molding process using the pressure molding row 97, so the adhesion between the two is relatively strong.
Base V-) When attaching powder to the surface after molding, it is difficult to obtain sufficient adhesion even when electrostatic adhesion is used, so increase the adhesion by using an appropriate adhesive. It is hoped that
