剤層６を設けた構成が一般的であった。As a transfer foil for transferring this hologram image, a resin layer 3 having a hologram layer 2 is formed on the surface of a base material 1 as shown in FIG. It has been common to have a structure in which a metal vapor deposition layer 5 and a heat-sensitive adhesive layer 6 are further provided.
このため、前記転写箔を用いて転写すると、金属蒸着層
５上に樹脂層３が存在する状態となった。Therefore, when the transfer was performed using the transfer foil, the resin layer 3 was present on the metal vapor deposited layer 5.
このため金属蒸着上に樹脂層が存在するため、回折光強
度等の光学性特性を低下させてしまった。For this reason, since the resin layer is present on the metal vapor deposition, optical properties such as the intensity of diffracted light are reduced.

あった。<Problems to be Solved by the Invention> As described above, the presence of the resin layer on the metal vapor deposited layer during transfer deteriorates the optical characteristics of the hologram layer. To solve this problem, the metal vapor deposited layer and the hologram layer can be peeled off, but since the hologram image is formed on the resin layer by heat pressure, if a resin with peelability is used for the hologram layer, the moldability will be affected. On the other hand, it has been impossible to provide a new resin layer on the hologram layer by coating or other methods to faithfully reproduce the hologram image.

ードアウトさせて剥離性を増す方法がある。Another method is to add plasticizers and additives to the hologram layer, form a metal vapor deposition layer, and then age it at a high temperature.
There is a method of increasing releasability by bleeding out the plasticizer or additive between the resin layer and the metal vapor deposited layer.

あった。However, since the hologram layer is formed using a stamper with a hologram image formed under high temperature and high pressure conditions, plasticizers and additives bleed out into the stamper.
This method could not be said to be suitable because the molding efficiency decreased.
本発明は、以上の点を鑑みホログラム画像を形成したス

With the goal.

着層が剥離せず、転写性が悪いものであった。Effect> Since the surface tension of the resin layer made of urethane resin made of two-component curable urethane is 34 to 40 dyne/c+m, the layer left as the resin forming the hologram layer is used to form a metal vapor deposition layer on the resin layer as it is. As a result, the metal vapor deposited layer did not peel off during transfer, resulting in poor transferability.

させることにより、樹脂層の表面にフッ素化合物が導入
され、表面張力が３Ｌｄｙｎｅ／ｃ■未満となり、転写
時に金属蒸着層の樹脂層からの剥離性が良好となった。Therefore, by contacting with plasma generated in an atmosphere of fluorine carbide compounds such as tetrafluoroethane and tetrafluoromethane, a fluorine compound is introduced onto the surface of the resin layer, and the surface tension becomes less than 3Ldyne/c■, resulting in metal vapor deposition during transfer. The peelability of the layer from the resin layer became good.
