The present invention describes a method for the manufacture of a phosphor intensifying screen which eliminates the use of solvents and high processing temperatures. The method comprises blending a phosphor in a hardenable system (i.e., that is, as defined herein, a polymerizable or curable system) comprising phosphor in a radiation curable binder composition, coating the phosphor in a radiation curable binder composition onto a substrate, and polymerizing (i.e., hardening) the system by exposure to actinic radiation. The radiation curable binder composition comprises an organopolysiloxane or a mixture of organopolysiloxanes.
Procédé de fabrication d'un écran intensificateur au phosphore éliminant l'utilisation de solvants et de traitements à haute température et consistant: à mélanger du phosphore à un système durcissable c'est-à-dire un système polymérisable ou durcissable du type défini ici) comprenant du phosphore et intégré à une composition liante radiodurcissable; à revêtir un substrat du phosphore contenu dans ladite composition; et à polymériser (c.-à-d. faire durcir) le système en l'exposant à un rayonnement actinique. Le liant radiodurcissable consiste en un organopolysiloxane ou en un mélange d'organopolysiloxanes.
