するのが望ましい。 Next, in the manufacturing method of the present invention, the transfer sheet does not need to be attached completely along the mold surface of the mold. This is because the heat and pressure during injection molding causes the transfer sheet to be molded into a shape that perfectly follows the mold surface of the mold. Further, in order to facilitate thermoforming, it is desirable to preheat the transfer sheet before mounting it on a mold.

であるので製造が容易である。 As described in detail above, according to the manufacturing method of the present invention, a decorated molded product can be obtained by simultaneously performing molding of a molded product and transfer painting onto the surface of the molded product.
Furthermore, in the present invention, the transfer sheet is molded into a shape that follows the mold surface of the mold using heat and pressure during injection molding, and the adhesive layer surface is adhered to the injection resin to transfer the design printing layer to the surface of the molded product. Therefore, even the surface of a molded product having unevenness can be easily decorated. Further, in the present invention, it is not necessary to preform the illustrated sheet and trim unnecessary portions of the illustrated sheet, so that manufacturing is easy.
