理由から各種分野において最近注目されている。The molded transfer foil is constructed by providing a transfer layer (design layer, etc.) on a base film that has heat resistance, mold releasability, etc. After placing a transfer foil preformed into a circular shape by vacuum forming into a mold, molten resin is injected into the mold to perform injection molding, and after demolding, the base film is peeled off! By removing it, a desired transfer layer can be transferred to the surface of the injection molded product. In particular, this transfer foil has recently attracted attention in various fields because injection molded products with complex three-dimensional shapes with high-quality surface designs can be easily and quickly obtained.
このような転写箔では基材フィルムが、より精度の高い

しまい、表面意匠性を損ねる問題があった。(Problem to be Solved by the Invention) However, among the various base films conventionally used as base films for molded transfer foils, there is no film that sufficiently combines the above-mentioned characteristics. There was no film that satisfied the characteristics of uniformity (smoothness).For example, in the case of Sei-bi film produced by the extrusion method, slugs remained on the surface, and horn marks were generated due to the contamination of dust, etc.; Membrane films have problems such as leaving marks from calender rolls, etc., and when a transfer foil using such a base film is used for one transfer, minute irregularities are formed on the surface of the injection molded product. There was a problem that the surface design was impaired.

まれるためである。Further, by laminating the base film of the present invention with a creative film, it becomes possible to easily separate the base film after injection molding. Furthermore, by configuring the thermoplastic resin layer to have a structure in which it is sandwiched between two biaxially stretched films, a thermoplastic resin layer particularly excellent in surface uniformity and f-lubricity can be obtained. This is because the die lines generated during melt extrusion in the molding die are offset by the films on both sides, and the mixed dirt and the like are pushed into the resin and thrown away.
