Radiation image storage panel.

摘要

Disclosed is a radiation image storage panel having at least one stimulable phosphor layer on a support and a protective layer provided on the stimulable phosphor layer, wherein the protective layer comprises at least two layers of which regains under a relative humidity of 90% on a sorption isotherm at 25°C are different by 0.5% or more.

According to this invention, a radiation image storage panel which has good humidity resistance and can be used for a long term is obtained.
