I can't get it. In addition, when a large amount of aluminum powder or mica pearl pigment is blended, there is a problem that the molding failure rate due to plate-out of the aluminum powder or mica pearl pigment is increased, and the physical properties of the resin are reduced.

m, preferably 10 to 100 μm, and the difference in refractive index from the thermoplastic resin is within ± 0.1, preferably ± 0.1.
It is within 0.06. Incidentally, the refractive index in the present invention means the value n D 20 measured by the Abbe refractometer. If the difference in the refractive index exceeds 0.1, the hiding becomes large and the metallic feeling is hardly developed.

配合すると、物性が低下する傾向にある。The dispersible particles are preferably blended in an amount of 0.1 to 100 parts by weight, preferably 1 to 50 parts by weight, based on 100 parts by weight of the thermoplastic resin. When the amount is less than 0.1 part by weight, a metallic feeling is developed, but tends to be slightly inferior to the above preferred range.

術が同等のメタリック感を得るための配合に比べて極め
て少量である。The thermoplastic resin composition of the present invention is blended with metal powder, pearl pigment, and the like, which have been conventionally used to obtain a metallic feeling. In addition, since the thermoplastic resin composition of the present invention contains dispersible particles having a refractive index similar to that of the thermoplastic resin serving as the matrix layer, the incident light is scattered, and the metal powder and the pearl pigment are dispersed. By reducing the orientation, a high metallic feeling can be obtained even with a small amount of metal powder or pearl pigment. That is, in the present invention,
With respect to 100 parts by weight of the thermoplastic resin composition, the content of these pigments may be about 0.1 to 4.0 parts by weight, which is extremely small as compared with the conventional technique for obtaining the same metallic feeling. .

勘案して適宜決定する必要がある。As described above, the average particle size of the dispersible particles is 1 to 200 μm, preferably 10 to 100 μm, but a large average particle size is desirable to increase light scattering. However, when the dispersible particles having a large average particle size are dispersed, the physical properties of the composition are greatly reduced. Therefore, it is necessary to appropriately determine the composition in consideration of the purpose of use.
