Abstract
A radiographic intensifying screen comprising a support and a phosphor-containing resin layer provided thereon, in which the void ratio of said phosphor-containing resin layer is reduced in comparison with an ordinarily prepared phosphor-containing resin layer having the same binder-phosphor ratio and formed by a coating procedure conducted under an atmospheric pressure. The void ratio is not more than 85% of the void ratio of the ordinarily prepared phosphor-containing resin layer for a phosphor-containing resin layer which contains a resinous binder and a phosphor in a weight ratio of 1:1 to 1:25, the ratio of 1:25 being exclusive, and the void ratio is not more than 90% for a phosphor-containing resin layer which contains a resinuous binder and a phosphor in a weight ratio of 1:25 to 1:100.
