Radiation image storage panel having low refractive index layer and

Abstract

There are disclosed a radiation image storage panel having a stimulable layer and a protective layer on a support, which comprises a layer having a lower refractive index than the protective layer is provided between the stimulable phosphor layer and the protective layer; and a process for preparing a radiation image storage panel composed of a support, a stimulable phosphor layer and a protective layer, and a protective layer supporting member is so provided between layers of the support and the protective layer as to surround and seal edges of the stimulable phosphor layer, which comprises the steps of providing at least one notch to the protective layer supporting member which functions as a vent hole, heating and drying the radiation image storage panel, and then fusing and sealing the notch or notches.
