Radiation image storage panel having low refractive index layer and protective layer |
(57) 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
