Summary: | PROBLEM TO BE SOLVED: To provide a pachinko machine front glass protection film capable of suppressing emission of blue light, and a pachinko machine in which the emission of blue light is suppressed by the pachinko machine front glass protection film.SOLUTION: The pachinko machine front glass protection film is configured to be adhered on a rear side of front glass of a pachinko machine and includes means for attenuating blue light, the means including a synthetic resin base material layer and an adhesive layer that is laminated on one surface side of this base material layer. It is preferable to include a hard coat layer laminated on another surface side of the base material layer. It is preferable that pencil hardness on the other surface of the hard coat layer is equal to or more than 2H. It is preferable to use, as the blue light attenuation means, a yellow phosphor that is excited by blue light and emits yellow light, or a light absorbent absorbing blue light.
【課題】ブルーライトの出射を抑制することができるパチンコ台フロントガラス保護フィルム及びこのパチンコ台フロントガラス保護フィルムによってブルーライトの出射が抑制されたパチンコ台の提供を目的とする。【解決手段】本発明のパチンコ台フロントガラス保護フィルムは、パチンコ台のフロントガラスの裏面側に貼着するパチンコ台フロントガラス保護フィルムであって、合成樹脂製の基材層と、この基材層の一方の面側に積層される粘着層とを備え、青色光を減衰させる手段を有する。上記基材層の他方の面側に積層されるハードコート層をさらに備えるとよい。上記ハードコート層の他方の面の鉛筆硬度が2H以上であるとよい。上記青色光減衰手段として、青色光により励起されて黄色光を発する黄色蛍光体又は青色光を吸収する光吸収剤を用いるとよい。【選択図】図1 |
