    摘要: In an intensifying screen composed of a support layer, a phosphor layer and a protective layer or of a support layer, a reflective layer, a phosphor layer and a protective layer, a carbon black layer is interposed between the support layer and the phosphor layer or the reflective layer. Further, antistatic agents are mingled in the protective layer.

    摘要: An intensifying screen having high physical durability and chemical resistance in which a curable resin is used as a resinous binder of a radioluminescent phosphor can easily be manufactured by employing an ultraviolet radiation-curable resin composition as the resinous binder. A dispersion comprising the ultraviolet radiation-curable resin composition and the radioluminescent phosphor dispersed in the composition is applied to the surface of a support to form a coating on the support, and the coating is cured by exposure to ultraviolet radiation to form a fluorescent layer on the support.
