摘要： There are disclosed a radiation image storage panel which comprises a stimulable phosphor layer on a support, wherein the stimulable phosphor layer has a fine pillar-shaped block structure, and a process of making a radiation image storage panel having a stimulable phosphor layer on a support, which comprises getting the stimulable phosphor layer having a fine pillar-shaped block structure. Scattering of the stimulation exciting light within the stimulable phosphor layer of the present invention can be markedly reduced since the stimulable phosphor layer has a block structure shaped in fine pillars, whereby it is possible to improve sharpness of the image. Also, radiation sensitivity and graininess of the image can be improved by enlargement of the stimulable phosphor layer without lowering sharpness of the image since lowering in sharpness of the image due to increase of the stimulable phosphor layer is little.

摘要： 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 in which contains a resinous binder and a phosphor in a weight ratio of 1 : 1 to 1 : 25, the ration of 1 : 25 being exclusive, and the void ratio is not more than 90 % for a phosphor-containing resin layer in which contains a resinous binder and a phosphor in a weight ratio of 1 : 25 to 1 : 100.

摘要： A radiographic intensifying screen comprising a support and a phosphor layer provided thereon which comprises a binder and a phosphor dispersed therein, characterized in that said binder contains a (meth)-acrylic copolymer in the amount of 5 - 100 % by weight, having repeating units represented by the formulas (I), (II) and (III):
in which each of R,, R 3 and R 5 is independently a hydrogen atom or an alkyl group; R 2 is a group selected from those consisting of an alkyl group, a cycloalkyl group, an aryl group, a heterocyclic group and an aralkyl group; R 4 is a hydrogen atom or an alkyl group, provided that R 4 is not identical to R 2 ; and x, y and z which represent molar percents are numbers satisfying the conditions of 5 ≦ x ≦ 99, 1 ≦ y+z z ≦ 95 and x+y+z≧ 90. The (meth)acrylic copolymer is preferably employed in combination with a linear polyester having a hydroxyl value in the range of 20 - 70.-

摘要： A composite material comprises a radiation image storage panel composed of a light-shielding substrate and a phosphor layer containing a stimulable phosphor and provided on the substrate, and a light-shielding sheet positioned on the surface on the phosphor layer side of the radiation image storage panel in a manner separable from the surface. The light-shielding sheet is made of a material interrupting stimulating rays which excite the stimulable phosphor, but permeable to a radiation passing through an object.
