Abstract
In a radiation image storage panel comprising a support, a phosphor layer containing a stimulable phosphor and a binder, and a protective film superposed in this order, the improvement in which the thickness of the phosphor layer at the edge on at least two sides being opposite to each other is less than the mean thickness of the phosphor layer and the density of the stimulable phosphor at said edge is higher than the mean density of the stimulable phosphor in the phosphor layer.

In a radiation image storage panel comprising a support, a phosphor layer containing a stimulable phosphor and a binder, and a protective film superposed in this order, the improvement in which the thickness of the phosphor layer at the edge on at least two sides being opposite to each other is thinner than the mean thickness of the phosphor layer and the density of the stimulable phosphor at said edge is higher than the mean density of the stimulable phosphor in the phosphor layer.
A process for preparing a radiation image storage panel comprising a support, a phosphor layer containing a stimulable phosphor and a binder, and a protective film superposed in this order by cutting a continuous radiation image storage panel sheet material, in which at least two edges of the panel being opposite to each other are formed by simultaneously cutting the continuous panel sheet material by means of a cutter having an angled edge.
