を表現することができる。2. Description of the Related Art Conventionally, as a method of decorating a plastic molded product or the like with metallic luster, a decorative sheet having a metal thin film layer or the like formed on a base sheet is supplied into an injection molding die, and a three-dimensional pattern is formed. There is a method in which a decorative sheet is integrally adhered to a molded article at the same time as a shaped article is molded to perform decoration. Since the glittering decorative sheet having such a configuration has a metal thin film layer, it is possible to express a pattern with high glitter using metallic luster.

れるため、アルミニウム膜などが用いられる。Since a three-dimensional processability is required for the base sheet, a film made of an acrylic resin, a polycarbonate resin, a vinyl chloride resin, a polyester copolymer resin, an amorphous or low-crystalline polypropylene resin or the like is used. Since the metal thin film layer also requires three-dimensional workability, an aluminum film or the like is used.

縮するので適していない。In order to form a metal thin film layer, a vacuum forming method or the like is usually used. However, since a base sheet having three-dimensional workability undergoes severe thermal expansion and contraction, it is not suitable to form a metal thin film layer partially by a vacuum evaporation method or the like because the base sheet partially expands and contracts.

Hardness H and thickness 20
There is a sheet in which a thermoplastic sheet having a three-dimensional workability of 0 μm or more is used as a base sheet, and a metal thin film layer is formed thereon by a transfer method. In addition, hardness HB or less, thickness 200 μm
The above-mentioned thermoplastic sheet having three-dimensional processability is used as a base sheet, and a metal thin film layer is formed thereon by a transfer method. Some are stacked.

ート側を一体化接着させる方法があった。[0007] In order to obtain a glittering decorative molded article using such a glittering decorative sheet, the glittering decorative sheet is three-dimensionally processed by a vacuum forming method, preliminarily molded, and punched into a desired shape. After that, it is put into a mold for injection molding, and after clamping the mold, the molding resin is injected into the cavity, and the base sheet side of the glittering decorative sheet is integrally bonded to a resin molded product obtained by solidifying the molding resin. A method in which the glittering decorative sheet is heated and sucked in a mold and clamped, and then the molding resin is injected into the cavity, and the base sheet side of the glittering decorative sheet is integrally bonded to a resin molded product obtained by solidifying the molding resin. was there.

た。The former glittering decorative sheet having the metal thin film layer transferred onto the base sheet has a high thermal softening temperature, so that it takes time for preheating during vacuum forming, and the heat transfer of the thermoplastic sheet and the metal thin film layer When the time of preheating is shortened due to the movement of the base material, or when the preheating time is shortened, it is impossible to follow the three-dimensional shape, and the base sheet is whitened.

After laminating the cover sheet or after the preliminary molding, residual stress such as resin shrinkage acts, and there is a problem that a minute displacement occurs in a portion in contact with the metal thin film layer, and delamination occurs.

トするのが困難となる。When a low hardness sheet 2 having a thickness within this range is used, the sheet has sufficient flexibility even at a temperature lower than the softening point, so that even if the molded article has a sharp shape such as a groove, the shape is not changed. Following, even if the molding shape in the preliminary molding is insufficient, the low-hardness sheet 2 does not whiten when it is placed in the mold 6 and clamped. Here, if the hardness of the low-hardness sheet 2 exceeds B, when the low-hardness sheet 2 is laminated with the high-hardness sheet 3, it becomes too hard and easily whitens when the mold is clamped. The low-hardness sheet 2 has a thickness of 50 μm.
If less than the above, uniform film formation becomes difficult in the film formation process of the low hardness sheet 2. On the other hand, when the thickness exceeds 500 μm, when trimming an unnecessary portion of the glittering decorative sheet 1, the glittering decorative sheet 1 becomes too soft, so that it is difficult to cut with a punching die.

能になる。In particular, it is preferable that the low hardness sheet 2 is made of an acrylonitrile-butadiene-styrene copolymer resin (ABS resin). For molded products made of acrylic resin, which are widely used as interior and exterior parts of automobiles, without intervening an adhesive layer,
This is because bonding can be performed by thermocompression bonding. Further, by increasing the amount of butadiene in the ABS resin, the hardness and softening point are lowered, and molding at a lower temperature becomes possible.

Here, if the hardness of the high hardness sheet 3 is less than H, depending on the type of the metal thin film layer 4 to be laminated, the hardness HB generally required as an interior part or an exterior part of an automobile may not be satisfied. There is. If the thickness of the high hardness sheet 3 is less than 50 μm, the film thickness may not be constant at the time of film formation, and sufficient surface strength may not be exhibited due to the influence of the low hardness sheet 2. On the other hand, if it exceeds 200 μm, whitening may occur during processing.

If the low-hardness sheet 2 and the high-hardness sheet 3 are of the same type of resin, they can be brought into close contact with each other without using an adhesive. Even if the low-hardness sheet 2 and the high-hardness sheet 3 are not made of the same resin, a sufficient adhesion strength can be obtained by selecting an appropriate lamination method.
