In recent years, the shape of a molded article has become more complicated. For example, an adhesive layer of a transfer foil for simultaneous molding is formed at a gate portion where a resin melts and flows into a mold at the time of injection molding. With the flow deformation, the metal thin film layer is also distorted by this, and cracks etc. are generated in the metal thin film layer that cannot be deformed following the distortion, often causing defects in the metallic luster of the obtained product. Can be seen. As countermeasures against this, various measures have been taken such as not providing a metal thin film layer at the gate portion, or reducing the complicated shape portion at the expense of the design of the molded product itself. In addition, it has been proposed to reduce the thickness of the metal thin film layer and to sacrifice the metal gloss to follow the deformation of the metal thin film, but the metal gloss at the corner is often unsatisfactory. there were.

Further, a method has been proposed in which cracks in the metal thin film layer are prepared in advance, and as described in JP-A-6-135198, defects due to the cracks are covered with a metal powder layer. However, it is not economically advantageous because the metal layer is doubled, and it is not only the case that the gloss of the metal thin film can be completely complemented. It has also been proposed to use a specific metal thin film for the metal thin film layer as disclosed in Japanese Patent Publication No. Sho 60-11633, but the metal thin film layer has a followability to a non-planar surface during molding. However, instead of transferring, the metal thin film layer is formed directly on the forming sheet.If the thickness of the forming sheet exceeds a specific thickness, the metal thin film layer is formed continuously. It becomes difficult to provide a protective layer or another layer, and in many cases, it is not practical from an economic viewpoint. The present invention solves the problems of the conventional transfer foil for molding and the like, by compression molding and the like,
Excellent metal luster with excellent metallic luster by preventing the destruction of the metal thin film layer due to the flow of the adhesive layer in the transfer foil for simultaneous molding and the occurrence of cracks in the metal thin film layer due to insufficient deformation followability of the metal thin film layer during molding An object of the present invention is to provide a metal thin film laminate for molding, for example, to obtain a decorative moldable product.

In the present invention, the thickness of the metal thin film layer is preferably 10 to 100 nm, more preferably 15 nm.
m to 50 nm. By setting the film thickness in such a range, the metallic luster is sufficient, cracks are hardly generated in the thin film, and the film is economically excellent. When the thickness is less than 10 nm, its performance in luster (metallic luster) is poor. When it exceeds 100 nm, even if the thickness is further increased, the effect is small and economically advantageous. Instead, cracks are more likely to occur. The formation of this metal thin film layer on the thermoplastic polymer sheet surface is as follows:
First, a metal thin film layer was formed on a long film base material such as a polypropylene film or a polyester film (if necessary, a protective layer described later was formed on a film base material provided with a release layer). With or without an adhesive layer, a transfer material is obtained, and this transfer material is laminated on a thermoplastic polymer sheet surface with or without an adhesive layer to peel off the film substrate. Alternatively, when the film substrate can be a protective layer, it is obtained as it is. The method for forming the metal thin film layer on the long film substrate is not particularly limited in the method, and a dry thin film forming method such as vapor deposition, sputtering, or ion plating is appropriately used. The sputtering method is preferable for forming the alloy thin film layer in order to keep the alloy composition uniform.
