The heating condition of the sling is 70 to 9 (TC and about 30 minutes to about hrs. <Use of the curable composition> The cured product obtained from the curable composition can be used as a enamel sheet of a type of lens sheet or Antireflection film, etc. (稜鏡 稜鏡 ) 稜鏡 稜鏡 稜鏡 稜鏡 稜鏡 ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( It is preferable that the synthetic resin such as acrylic resin or polycarbonate is preferably excellent in light transmittance. In the case of producing a crucible sheet, an active energy ray hardening combination is injected into a predetermined molding mold, or Further, the curable composition is heated, and after the substrate is placed at the pre-twisting position of the shaping mode, the curable composition is cured by irradiation or heating with an active energy ray. In the case where the active energy entangled composition is hardened by irradiation with ultraviolet rays, for example, a mercury lamp or a metal guillo lamp is used, and an ultraviolet light having an integrated light amount of 1 〇〇 to 5000 mJ/cm 2 is ideal. . On the one hand, in the case where the electron beam is hardened, it is preferable to accelerate the voltage by 150 to 250 keV and 1 to 20 Mrad. (Anti-Reflection Film) The anti-reflection film is formed by providing a layer formed of a curable composition on a base film, and further providing an anti-reflection layer thereon. In the case of a base film, a synthetic resin can be used. A sheet, a glass plate or the like, but it is preferably a polyethylene terephthalate, an acrylic resin, a polycarbonate or a glass from the viewpoint of transparency.
