本発明は金Ｂ薄膜居の転写方法に関し、詳しくは表面が
粗面の被転写体に対しても鏡面性に優れた金属光沢を発
現し得る金Ｒ薄膜層の転写が可能な転写方法に関する。[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a method for transferring a gold B thin film, and more specifically, to a method for transferring a gold B thin film, which exhibits a metallic luster with excellent specularity even on a transferred object with a rough surface. The present invention relates to a transfer method capable of transferring a gold R thin film layer to be obtained.
従来より、金属薄膜層を存する転写シートを用いて核層

この種の転写方法としては、金Ｒ’ｒ”Ｎ膜層を有する
転写シートを加熱ロールにて転写する方法、金属薄膜層

知られている。Examples of this type of transfer method include a method in which a transfer sheet having a gold R'r"N film layer is transferred using a heated roll, a method in which a metal thin film layer is transferred using a reactive hardening resin or an adhesive, etc. Are known.

た。However, according to the conventional method of transferring a metal thin film layer, if the surface of the object to be transferred is a rough surface with minute irregularities, the transferred metal thin film layer itself is inferior in smoothness corresponding to the rough surface condition. As a result, it was impossible to transfer a metal thin film layer with excellent specularity and metallic luster.

ィングすることが困難なため結局、金属薄膜層表面を鏡
面とすることができない問題があった。For example, in the former transfer method described above, although the adhesive for adhering the metal thin film layer to the object to be transferred is melted by the heat generated by the heating roll, it follows the minute irregularities on the surface of the object to be transferred and becomes rough. The condition also affects the thin film layer, making it difficult to obtain a mirror surface.Also, in the latter transfer method, there is a disadvantage that the curing time of the resin is long when using a reactive curable resin, and this curing time can be shortened. However, when using adhesives, the surface of the metal thin film layer becomes cloudy due to the heat generated by the curing reaction.On the other hand, in the case of adhesives, it is difficult to coat the surface of the object to be transferred with the adhesive so that it becomes a smooth surface. Since it is difficult to do this, there was a problem in that the surface of the metal thin film layer could not be made into a mirror surface.

The purpose is to provide a transcription method.

This irradiation may be performed from the transfer sheet side as in this embodiment, or from the transfer object side if the object to be transferred is capable of transmitting ultraviolet rays. Since the film 2 is transparent, it is possible to irradiate ultraviolet rays from the transfer sheet side. Irradiation with ultraviolet rays is performed, for example, by running five high-pressure mercury lamps (120 W/cm) at a speed of 2 m/min.

ものとなる。In the transfer method of the present invention, the fluid ultraviolet curable resin 6 as described above is interposed between the transfer sheet 1 and the transferred object 7 during the transfer, so that the fluid resin 6 as shown in FIG. In addition to compensating for the fine irregularities I2 on the surface of the transfer target 7, the resin surface 13 on the opposite side from the fine irregularities 12 of the resin 6
becomes a smooth surface, and the metal thin film M3 formed on the release film 2 with a smooth surface transfers onto the smooth surface 13 as it is, and as a result, the metal FiJ film 3 is affected by the fine irregularities 12 of the transfer target 7 As is clear from the above, even if the surface of the transferred object has a rough surface with minute irregularities, the transferred gold is transferred to the object 7 with a smooth surface. BF4FITi3 always maintains its smoothness, and therefore can exhibit excellent specular metallic luster.
