高硬化用ホットスタンピング箔に係るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention is capable of producing hardness that was previously impossible by irradiating electron beams or ultraviolet rays to a protective film that has been heat-pressure-transferred onto molded materials such as plastics and metals. This relates to hot stamping foil for high hardening.
プラスチックス、金属等の成型素材に対し、その表面保
護、美感を持たせる方法の一つとして、ホットスタンピ
ング箔が用いられている。Hot stamping foil is used as a method to protect the surface of molded materials such as plastics and metals, and to give them an aesthetic appearance.
熱圧転写された保護皮膜は耐擦傷性、耐磨耗性が要求さ

乾燥によるＨＢ径程度硬さを持たせた後、成型素材に熱
圧転写されていたが、次記のとおりの欠点があった。The heat-pressure-transferred protective film is required to have scratch resistance and abrasion resistance, so conventionally the hot-stamping foil protective film was dried with hot air to give it a hardness equivalent to the HB diameter, and then heat-pressure transferred to the molding material. However, it had the following drawbacks.

Because it is carried out at a high temperature and pressure of 8000 #/d,
If the protective film has a hardness equivalent to the HB diameter as in the past,
During hot-pressure transfer, flakes occur in the protective film, which not only impairs the aesthetic appearance, but also requires a lot of effort and time to remove the flakes.

（８） 保護皮膜がＨＢ程度に硬いと、熱圧転写時に保
護皮膜と真空蒸着皮膜との間に眉間剥離が発生し、保護
皮膜が剥離してしまう虞れがある。(8) If the protective film is as hard as HB, there is a risk that glabellar peeling will occur between the protective film and the vacuum-deposited film during heat-pressure transfer, resulting in the protective film peeling off.
