しとる方法である。The 2P method uses an ultraviolet curable resin containing a base polymer, a diluent, a photoinitiator, etc., and pours the resin between a Ni stubber and a substrate to transfer the information tracks on the stubber onto the substrate.
２Ｐ法の場合、使用する樹脂の耐熱性、吸水性などが重
要であり、耐熱性が低い場合、消去。In the case of the 2P method, the heat resistance and water absorption of the resin used are important, and if the heat resistance is low, it will be eliminated.
