Abstract
Abstract A radiation image storage panel having a phosphor layer comprising a stimulable phosphor and a binder, wherein the binder comprises a thermoplastic elastomer having a softening or melting point of 30° to 150° C. and a modulus of elasticity of not more than 0.3 kgf/mm 2 is resistant to production of cracks in its repeated use in a radiation image recording and reproducing method.
