The thickness of the coating film of the hard coat agent is 0.5 to 10 μm
It is preferable to use a range of extent, from the viewpoint of continuous mass production of transfer foil without wrinkles or cracks,
If it is thinner than 0.5 μm, it is a stable and homogeneous protective layer (3).
Is not obtained, and it is difficult to obtain a transfer foil exhibiting sufficiently excellent weather resistance and abrasion resistance, and when it is more than 10 μm, transfer formation of a delicate pattern becomes difficult, which is not preferable. Further, the protective layer (3) forming the protective layer (3) may be appropriately colored with a coloring agent in advance.

色したものも用いることが出来る。The thickness of the adhesive layer is usually selected from the range of 0.2 to 5 μm. If the thickness is less than 0.2 μm, a sufficient adhesive effect cannot be obtained. On the other hand, if the thickness exceeds 5 μm, the adhesive layer is too thick and transfer formation of a delicate pattern becomes difficult, which is not preferable. In addition, the drying speed becomes slow and it is inefficient. In addition, the original adhesive strength cannot be obtained, and adverse effects such as residual solvent occur.
Further, as the adhesive forming the adhesive layer, one which is appropriately colored with a coloring agent in advance can be used.
