2. Description of the Related Art Conventionally, metal particles have been used to impart a metallic-like glitter to a synthetic resin molded article, and the glitter is mainly expressed by reflection of the long axis surface of the metal particles. However, this sometimes resulted in appearance defects such as weld lines on the surface of the molded product. The weld line is a phenomenon that occurs when a thermoplastic resin is formed by injection molding or the like, and is located at a position where a molten resin branches and flows along a flow path in a mold, merges again, and is completely fused. It occurs linearly and significantly reduces the commercial value of the product. Although the weld line phenomenon has not been elucidated in detail, in the case of a thermoplastic resin containing metal particles, the thermal conductivity is higher than that of a non-containing thermoplastic resin, which may cause a decrease in the temperature of the molten resin flowing in the mold. It is believed to be the cause. Especially flat filler
In this case, the major axis direction of the filler is oriented along the flow of the resin. In other words, the molten resin merges again in the mold and is completely fused, and when the resin flows inward in the mold, the filler also likewise squeezes, so that the filler is consequently formed on the surface of the molded product. The short axis part of is turned. At this position, the glitter was weakened, and the weld line tended to be relatively conspicuous when the filler concentration was high.

As a solution to the weld line, metal plate-like particles having an average particle diameter of 10 μm (Japanese Patent Publication No. 6-4718), metal particles having a major axis and a minor axis defined in a shape ratio of 1/8 to 1 ( JP-B-4-5562, JP-B-6-9
No. 9592, Japanese Patent Publication No. 6-99593, Japanese Patent Publication No. 6-99594, Japanese Patent Publication No. 7-81094, and specific aluminum particles (JP-A-11-2931).
No. 07) is disclosed, but in any case, it is not possible to completely suppress the occurrence of a weld line in the molded product, and there is a possibility that a clear color may not be obtained due to glaring, darkening, poor dispersion and the like. Was.

Furthermore, when these are used as condensation resins (polyester, nylon, etc.), there is a possibility that problems such as a decrease in mechanical properties due to hydrolysis caused by water adsorbed on the particle surface may occur.

Further, pearl-based metal particles in which glass flakes and mica surfaces are coated with a metal such as titanium oxide (Japanese Patent Publication No. Sho 62-156164,
JP-A-158540 and JP-A-10-158541), there is also an example in which glitter is imparted, but this also has no effect on suppressing the occurrence of weld lines. In addition, the particles themselves are brittle and cracks or breaks occur on the particle surface due to the shearing force received during processing or molding, and the expected color tone can not be obtained, and it has been used for automotive products, miscellaneous goods, containers, indoor and outdoor building materials, etc.
There was a problem that the commercial value of the molded article was greatly lost.

[0006] Accordingly, it has been highly expected that the development of the expected color tone, the suppression of the occurrence of weld lines, and the production of a brilliant thermoplastic resin molded product having good mechanical properties at low cost are highly expected.

[0007]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a molded article having an excellent appearance of an elegant brilliant color tone and suppressed appearance of weld lines, and having good mechanical properties.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, a liquid crystal polyester (A), which is a kind of cholesteric liquid crystal, is used as a glittering substance. A cholesteric liquid crystal has a layered structure similar to a smectic liquid crystal, but has a molecular long axis in a layer plane similar to a nematic liquid crystal in a parallel arrangement. Further, the basic skeleton has a structure in which polyester or polyesteramide, or both of them, and mesogen in a side chain. Therefore, since the orientation of the molecular axes is slightly shifted with a constant period, the entire molecule forms a helical (spiral) structure. These molecular chains are arranged and crystallized in a uniaxial direction, and exhibit a liquid crystallinity of a helical (spiral) structure as a whole. Optical properties such as optical rotation, selective light scattering, and circular dichroism of the cholesteric liquid crystal are based on this helical structure.

The cholesteric liquid crystal, which is a spherical, columnar or elliptical particle, is obtained by overlapping several layers of such helical molecular chains. Since the cholesteric liquid crystal reflects in the entire spectrum of visible light by this structure, the color tone changes continuously from a vertical plane to a horizontal plane depending on the viewing direction. Therefore, at the position where the molten resin branches and flows along the flow path in the mold, merges again, and is completely fused, the cholesteric liquid crystal also moves in the same direction as the flow of the resin when the molten resin passes inside the mold. The weld line phenomenon is suppressed because the luminosity is continuously exhibited from any angle.

The liquid crystal polyester (A) used in the present invention refers to a polyester or polyesteramide as a basic skeleton or a structure having both of them and having a mesogen in a side chain. In addition, the liquid crystal polyester (A) used in the present invention is preferably not melted at the processing temperature in order to uniformly disperse the particles in the form of islands in the molded article. If melted, it may not be uniformly mixed with the thermoplastic resin (B) or the like, and a molded product may have a flow mark or the like, which is not preferable. In particular, the deflection temperature under load (JIS K 7191) of the liquid crystal polyester (A) is more preferably 250 ° C. or more.

The liquid crystal polyester (A) used in the present invention can be obtained by a polymerization reaction such as dispersion polymerization or suspension polymerization, or mechanical pulverization of a commercially available resin.
