Abstract
PURPOSE: A substrate is provided with a first phosphor layer comprising one or more of Eu activated complex salt phsphor having three particular compositions and a second layer of CaWO4 phosphor disposed thereon. The resultant radiation sectitive paer provides high quality photography having an excellent sensitivity, vividness, grainedness and contrast.
CONSTITUTION: One or more of Eu activated complex salt phosphors as represented by formulas (1), (2) or (3), such as BaF2-BaCl2-0l.5KCl-0.2BaSO4:0.06Eu2+ phosphor of (2) is added with a binder resin such as nitrocellulose and a proper amount of solvent to forma coating composition. The coating composition is coated on a substrate such as paper to form an Eu activated complex salt phsphor layer. A CaWO4 phosphor coating composition is prepared in the same way as before and coated on the Eu activated complex salt phosphor layer to be dried for providing the aimed sensitive paper.
