  However, the conventional hot stamp method and thick-wall printing are still unsatisfactory in terms of insufficient three-dimensional visual effect and high quality texture.

  The present invention combines a sculpture-like pattern formed on a molded product with a surface decoration method using a coating film, a vapor-deposited film, and the like, to produce a visual effect having a more three-dimensional and high-quality texture. The challenge is to create.

The main structure concerning the decorative synthetic resin molded product of the present invention for solving the above problems is as follows.
Forming a pattern with a flat portion in a predetermined region of the back surface of the synthetic resin base material having transparency and an engraved recess formed in a sculpture shape leaving the flat portion in the periphery;
Forming a first decorative layer composed of at least one layer selected from a coating film and a vapor deposition film on a flat portion excluding the engraved recess in a predetermined region.

With the above configuration, the engraving-like pattern formed by the flat part and the engraved concave part, and the decorative layer made of a coating film or vapor deposition film selectively formed only on the flat part excluding the engraved concave part, Combined with the optical effect of the substrate having the property, the pattern can be more sculpted and three-dimensionally displayed.
Here, the coating film in the above configuration includes not only a film formed by a general coating method but also a printed film.
In addition, the first decorative layer is not limited to a single coating film or a vapor-deposited film. Depending on the purpose of decoration, for example, a colored transparent film is laminated on the vapor-deposited film to display a colored metallic luster. It can also be done.

  Another configuration of the present invention is that, in the main configuration described above, at least one film selected from a coating film and a deposited film is used as a transfer film.

  The coating film and vapor deposition film can be formed by painting, printing, vacuum vapor deposition, or transfer film, but by using the transfer film, only the flat part excluding the engraved concave part can be used even when the design is fine and fine. In addition, the first decorative layer can be formed with high accuracy along the design.

  Here, the transfer film is one in which a coating film or a metal vapor deposition film laminated on the transfer film is transferred to the surface of the molded product by a method using a hot stamp method or a pressure roll. This is a method to transfer the coating film or vapor deposition film so that it is pressed against the surface of the product, and since the pressing force does not act on the engraved recess, these films and vapor deposition film can be flattened without particularly high precision alignment. A decorative layer can be formed with high accuracy along the design only on the part.

  Still another configuration of the present invention is to deposit a coating film and a vapor deposition on the entire predetermined region including the flat portion and the engraved concave portion along the uneven shape related to the flat portion and the engraved concave portion, overlapping the first decorative layer. The second decorative layer made of at least one film selected from the films is formed by lamination.

  According to the said structure, although a pattern will be formed by the flat part which laminated | stacked the 1st decoration layer and the 2nd decoration layer, and the engraving recessed part which laminated | stacked only the 2nd decoration layer, these The texture of the flat and engraved recesses, the color density, the metallic luster, and the texture of the surface texture can be changed to give a delicate shade to the sculpture-like pattern, or the metallic luster can be changed slightly. Combined with the optical effect of the transparent base material, the design can be made deeper and more three-dimensional, and the color, color density, metallic luster or texture can be delicate. High-quality decoration can be realized by changing to.

Here, the second decorative layer is also composed of at least one film selected from a coating film and a vapor-deposited film. Besides the first decorative layer, the second decorative layer may be formed of a single film. For example, it can be selected to form a plurality of films such as coating film + deposited film + coating film, and in combination with the first decoration layer, the difference between the decoration of the flat part and the engraved recess can be made in various ways. It becomes possible to set.
In addition, the first decorative layer and the second decorative layer can be formed with the same color coating film to slightly change the color density of the flat portion and the engraved concave portion. Then, the metal gloss can be changed slightly by changing the deposition density.

  Still another configuration of the present invention is to add a configuration in which a decorative member having a reflective surface is used and the reflective surfaces are arranged in a stacked manner on the back surface side of the substrate.

According to the above configuration, the pattern can be more three-dimensionally and more complicatedly displayed by the optical effect of the reflected light from the reflecting surface of the decorative member arranged in a stacked manner on the back surface side of the base material. it can.
In addition, the stacking | stacking aspect to the back surface side of the base material of a decorating member is the aspect which made the decorating member contact | adhere to the 1st decorating layer or 2nd decorating layer formed in the flat part by the said structure. It is not limited to, It can also be set as the aspect which formed the clearance gap between the 1st decorating layer or the 2nd decorating layer.

In addition, the decorative member can be prepared in various modes such as a metal plate piece, a metal thin film piece, and a synthetic resin molded product in which a metal thin film such as a vapor deposition film is formed on the surface.
Further, the reflecting surface is not limited to a mirror surface that completely reflects light, but can also be semi-reflective that allows part of the light to pass.
In addition, the reflecting surfaces can be stacked over the entire predetermined region or can be partially stacked.

The decorated synthetic resin molded product of the present invention has the above-described configuration, and has the following effects.
That is, in the case of the main structure, a sculpture-like pattern formed by the flat portion and the engraved concave portion, and a coating film or vapor deposition film selectively formed only on the flat portion excluding the engraved concave portion The decorative layer made of can combine the optical effect of the transparent base material to make the pattern appear more sculpted and three-dimensionally.

  In the case where the coating film and the vapor deposition film are used as a transfer film, even when the design is fine and fine, a decorative layer can be formed with high accuracy along the design only on the flat portion excluding the engraved recess. .

  In the case of forming the second decorative layer, the design can be made deeper and more three-dimensionally displayed, and the color, color density, metallic luster or texture can be changed delicately to achieve high quality. Decoration can be realized.

  In the case where the reflecting surface is provided on the back surface side of the base material, the pattern can be more three-dimensionally and complicatedly displayed by the optical effect of the reflected light from the reflecting surface.
