ABSTRACT:
A radiographic itensifying screen has a support, a light-reflecting layer, a phosphor layer and a surface protective layer. The light-reflecting layer has a thickness of 15 to 100 .mu.m and is made of 25 to 75 vol. % of TiO.sub.2 particles having a mean particle size of 0.1 to 0.5 .mu.m and a polymer birder. The phosphor layer has a thickness of 40 to 120 .mu.m and contains particles of phosphor which gives a main luminance in a wavelength region of longer than 430 nm. This radiographic intensifying screen is preferably placed between an object to be exposed to radiation and a radiographic film.
