The transfer foil portion 4 ′ has the same shape as the transfer foil portion 4 of the second embodiment, and the transfer foil 3 ′ is formed in a shape along the outline of the transfer foil 4 ′ unlike the transfer foil 3 of the second embodiment. Has been. That is, it consists of a larger “M” formed along the outer contour line of the transfer foil 4 ′ and a smaller “M” formed along the inner contour line of the transfer foil 4 ′. As shown in FIG. 3D, the transfer foil 3 ′ is first transferred to the base leather, and the transfer foil 4 ′ is partially overlapped with the transfer foil 3 ′. Transcribed. Such a sense of shape irregularities can be reduced and a two-layer transfer foil can be obtained clearly.

(Other embodiments)
In another embodiment, the first transfer film (or the second transfer film) has a transfer foil portion having a predetermined shape from the transfer foil sheet, and a method for removing the periphery of the transfer foil portion as a first transfer film. You may make it remove by mechanical methods other than the transfer method by chemical etching or a transfer type | mold, without using a type | mold (or 3rd transfer type | mold).

  The transfer method of this embodiment will be described with reference to FIG. In addition, the same code | symbol is used as the same thing as Embodiment 1, and the description is simplified. As the first step 1 (S31), a transfer film in which a transfer foil sheet is coated with a protective film is prepared. In Step 2 (S32), the transfer foil portion having a predetermined shape is left from the transfer foil sheet of the transfer film, and the non-transfer foil portion on the outer periphery of the transfer foil portion is separated and removed in advance. As a result, as a third step (S33), a transfer film in which a transfer foil portion having a predetermined shape is left is created. In step 4 (S34), the transfer film and the panel member thus created are set in a transfer mold for transferring a transfer foil portion having a predetermined shape. In step 5 (S35), the transfer mold is heated and pressurized. As a result, as step 6 (S36), the transfer foil portion is transferred to the member panel surface.

  In step 4 (S34), the transfer film and the panel member may be pressed and transferred by other positioning means without using the transfer mold.

  In any of the above embodiments, the first transfer mold (or the third transfer mold) only removes the periphery of the transfer foil portion 2 (3, 4) in advance, and heat transfer between the transfer foil portion and the non-transfer foil portion. In order to prevent this, it is preferable that the transfer time at this time is short, and the shorter the time, the higher the transfer temperature and the quicker removal of the non-transfer portion is more preferable. In particular, it is possible to shorten the transfer time of the first transfer mold (or the third transfer mold) to be shorter than the transfer time of the second transfer mold (or the fourth transfer mold). It is preferable for clarifying the boundary of the portion 4a. The transfer time and transfer temperature vary depending on the material on the surface of the member and the material, shape, and thickness of the transfer portion. It suffices to have a time that can be transferred to the member, and it is preferable that the time is as short as possible to minimize the influence on the non-transfer portion. In the first transfer type (or the third transfer type), the transfer temperature is 80 ° C. to 170 ° C. It is preferable that the time is 0.01 to 5 seconds, particularly the transfer temperature is 100 ° C. to 150 ° C. and the transfer time is 0.05 to 2 seconds. In the second transfer type (or the fourth transfer type), the transfer time is 80 ° C. to 170 ° C., and the transfer time is to transfer the transfer portion to a member such as leather and securely bond it. It is preferable that the transfer temperature is 100 to 150 ° C. for 0.1 to 10 seconds, and the transfer time is 0.5 to 7 seconds.

  In the first or second embodiment, each transfer mold is transferred by heating and pressurizing to perform hot stamping. However, as in the third embodiment, a high frequency voltage is applied to all molds and some molds. You may make it transfer over. It is preferable to apply a high-frequency voltage because the transferred shape portion appears more clearly.

  Or in the said embodiment, it replaces with the metal mold | die which heats and pressurizes, and it may be set as a simple metal mold | die only with the metal mold | die to pressurize, and cost reduction may be aimed at. Also in this case, a high-frequency voltage may be added to produce a clear image.

  In any of the above embodiments, a paper member excellent in cost is used as the receiving member that receives the non-transfer portion.
