型で吸引する方法等がある。(Prior Art) In the method of patterning at the same time as resin molding, many ideas have been proposed to prevent wrinkles from forming in the base film, for example, as described in JP-B-50-19132. , The method of heating and softening the transfer film in a female mold for injection molding, and then vacuum suctioning to bring the transfer film into close contact with the mold, as described in JP-A-56-2148, There is a method in which hot air is blown from the injection mold in the mold and suction is performed with the receiving mold.

問題点を有していた。(Problems to be solved by the invention) As described above, it is possible to almost deal with a molded product having a smooth uneven shape by combining softening of the transfer film and vacuum suction, but the boundary of the uneven part is a corner. In the case of a shape having parts, there is a problem that air remains between the corner portion in the mold and the transfer film, and the presence of this air causes wrinkles in the transfer film during molding. It was
本発明は、このシワの発生を防止できる転写方法を提供

が入ることがない。(Means for Solving the Problems) The present invention will be described in detail with reference to the drawings. As shown in FIG. 1, only a flat portion (11) of a molded product (1) is provided with a pattern, and a recess (12) is formed. If there is no pattern on the
Use the transfer film (2) having the cutout portion (21) formed by removing the portion corresponding to 2). Although the cutout portion (21) is circular in FIG. 1, other shapes may of course be used. The size of the cutout portion (21) is designed to be larger than the size of the recessed portion (12). Therefore, when the transfer film is installed in the mold, there is no concern that the transfer film will overlap the convex part of the mold. No wrinkles on the transfer film.

ている。The structure of the transfer film used is the same as that conventionally used, such as a base film such as a polyester film, a release layer such as an acrylic resin, a pattern layer such as a wood pattern or an abstract pattern, an acrylic resin or the like. Made of heat sensitive adhesive layer.
切り抜き部分の大きさは成形品の凹部又は凸部の大きさ

分の直径が成形品の凹部又は凸部の直径よりも1mm以下
の差で大きければよく、切り抜き部分の方が小さければ
シワの発生を防止できず、差が1mm以上では模様の位置
精度が不良となるので好ましくない。The size of the cutout part is designed to be larger than the size of the concave or convex part of the molded product, but the allowable range is as long as the diameter of the cutout part is larger than the diameter of the concave or convex part of the molded product by 1 mm or less. If the cutout portion is smaller, wrinkles cannot be prevented, and if the difference is 1 mm or more, the positional accuracy of the pattern becomes poor, which is not preferable.

成形品を得た。(Example) When manufacturing a disk-shaped molded product having a diameter of 50 mm having a recess having a diameter of 16 mm in the central portion, a transfer film having a cutout portion having a diameter of 17 mm formed in the central portion was formed on the convex portion of the mold. Is installed in advance correspondingly, and then a polystyrene resin is injected to manufacture a disc-shaped molded product,
After removing the base film of the transfer film after demolding,
A molded product having no wrinkles and having a pattern on the surface portion other than the concave portion was obtained.
（発明の効果） シワの発生を完全に防止できる。(Effect of the invention) The generation of wrinkles can be completely prevented.
成形品に対する模様の位置精度が良好である。The positional accuracy of the pattern with respect to the molded product is good.

特徴とする成形同時転写方法。1. A transfer film in which a release layer, a pattern layer, and a heat-sensitive adhesive layer are sequentially formed on a base film is placed in a mold, and the base film is removed after the mold is filled with resin and molded. Therefore, in the method of simultaneously molding the resin and patterning the surface thereof, a transfer film is used in which the portions corresponding to the portions of the molded product that do not require patterning are used. A method for simultaneous transfer of molding, characterized in that the size of the removed portion is made larger than the size of the concave portions or convex portions of the molded product.
