(転写方法)
本発明の導電性フイルムからの基材への導電層の転写は、導電性フイルムと基材とを、当該導電性フイルムの仮支持体側が外側となるように張り合わせる工程と、張り合わせた導電性フイルムの導電層から仮支持体を剥離する工程とを少なくとも含む方法により行われる。
導電性フイルムと基材とを張り合わせた後に、導電性フイルムの導電層と水とを接触させると、導電層中のバインダーを膨潤させることができる。バインダーが膨潤すると、仮支持体と該導電層との剥離接着力は低下する(弱まる)ため、導電層と仮支持体との剥離をより容易に行うことが可能になる。したがって、仮支持体の剥離前に予め導電層を水と接触させておくことが好ましい。ゼラチンは適度な膨潤性を有するため、この観点からも、銀塩含有乳剤層中のバインダーとしてゼラチンを用いることが好ましい。
導電層と水との接触は、基材と張り合わせた導電性フイルムを水中、水蒸気中、又は相対湿度60〜100%の雰囲気中に保持することで行うことができる。密着させた導電性フイルムと基材をまるごと水中、水蒸気中、又は相対湿度60〜100%の雰囲気中に保持してもよい。
導電性フイルムを水中に保持する場合においては、水温は30℃以上であることが好ましく、30〜100℃であることがより好ましい。水温が低すぎると、バインダーが十分膨潤しない場合がある。
導電性フイルムを水蒸気中に維持する場合においては、水蒸気温度は90℃以上であることが好ましく、90〜150℃であることがより好ましい。水蒸気温度が低すぎると、バインダーが十分膨潤しない場合がある。
導電性フイルムを相対湿度60〜100%の雰囲気中に維持する場合においては、当該雰囲気の温度は90℃以上であることが好ましく、90〜150℃であることがより好ましい。雰囲気中の温度が低すぎると、バインダーが十分膨潤しない場合がある。
(Transfer method)
The transfer of the conductive layer from the conductive film of the present invention to the base material includes the step of bonding the conductive film and the base material so that the temporary support side of the conductive film is on the outside, The method includes at least a step of peeling the temporary support from the conductive layer of the film.
After bonding the conductive film and the substrate, when the conductive layer of the conductive film is brought into contact with water, the binder in the conductive layer can be swollen. When the binder swells, the peel adhesive force between the temporary support and the conductive layer decreases (weakens), so that the conductive layer and the temporary support can be more easily peeled off. Therefore, it is preferable to contact the conductive layer with water in advance before peeling off the temporary support. Since gelatin has an appropriate swelling property, it is preferable to use gelatin as a binder in the silver salt-containing emulsion layer also from this viewpoint.
The contact between the conductive layer and water can be performed by maintaining the conductive film bonded to the base material in water, water vapor, or an atmosphere having a relative humidity of 60 to 100%.

また、表1中、表面抵抗率及び接触抵抗は、25℃、相対湿度45%の条件下で、ロレスタGP(三菱化学アナリック社製)を用いて測定した。
また、表1中、「仮支持体と導電層との剥離接着力」は、25℃、相対湿度45%、引張速度50mm/minの条件下での90°剥離接着力であり、「膨潤後の導電層と仮支持体との剥離接着力」は、90℃、相対湿度90%の雰囲気中から取り出した導電性フイルムを、25℃、相対湿度45%雰囲気下に5分間静置した後、引張速度50mm/minで測定した90°剥離接着力である。剥離接着力は、電動式タテ型フォースゲージスタンド(FGS−VCシリーズ、日本電産シンポ社製)を用いて測定した。
In Table 1, the adhesion between the temporary support and the conductive layer was evaluated according to the following criteria.

B: 70% or more and less than 90% of the conductive layer is in close contact with the temporary support.
C: 50% or more and less than 70% of the conductive layer is in close contact with the temporary support.

In Table 1, “Peeling adhesive strength between temporary support and conductive layer” is 90 ° peeling adhesive strength under the conditions of 25 ° C., relative humidity 45%, and tensile speed 50 mm / min. The adhesive strength between the conductive layer and the temporary support ”was determined by leaving the conductive film taken out in an atmosphere at 90 ° C. and 90% relative humidity for 5 minutes in an atmosphere at 25 ° C. and 45% relative humidity. 90 ° peel adhesion measured at a pulling speed of 50 mm / min. The peel adhesive strength was measured using an electric vertical force gauge stand (FGS-VC series, manufactured by Nidec Sympo Corporation).
上記表1の結果から、バインダーを含有する銀塩含有乳剤層を露光して得た導電性フイルムであって、導電層と仮支持体との剥離接着力が本発明で規定する範囲内であるものは、仮支持体との密着性に優れると同時に、剥離が容易で導電層の転写性に優れることがわかった。すなわち、本発明の導電性フイルムは、仮支持体と導電層の間で、密着性と剥離性という相反する特性を良好に兼ね備えたものであることがわかった。

抗菌活性値の結果を下記表3に示す。 The results of antibacterial activity values are shown in Table 3 below.
一般に抗菌活性値が2以上であると、明らかな抗菌効果があると判断できるが、本発明品の抗菌活性値は2を大きく超えていた。本発明の導電性フイルムでは、導電層に占める金属銀部領域の割合が非常に小さくても、導電層の抗菌性に優れることがわかった。したがって、本発明の導電性フイルムを用いることで、抗菌性に優れた導電性基材を製造できることが示された。 In general, when the antibacterial activity value is 2 or more, it can be judged that there is a clear antibacterial effect, but the antibacterial activity value of the product of the present invention greatly exceeded 2. It has been found that the conductive film of the present invention is excellent in antibacterial properties of the conductive layer even if the proportion of the metallic silver portion region in the conductive layer is very small. Therefore, it was shown that the electroconductive base material excellent in antibacterial property can be manufactured by using the electroconductive film of this invention.

表4の結果から、本発明の導電性フイルムを用いて製造した導電性基材は、高度に延伸しても金属銀部の破断が生じにくく低い表面抵抗率を示し、導電性に優れることがわかった。また、延伸された導電性基材は、導電層と基材との密着性が維持されていた。 From the results of Table 4, the conductive base material produced using the conductive film of the present invention shows a low surface resistivity that is less likely to break the metallic silver portion even when highly stretched, and is excellent in conductivity. all right. In addition, the stretched conductive base material maintained the adhesion between the conductive layer and the base material.
