Section: claims

1. 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.degree. to 150.degree. C. and a modulus of elasticity of not more than 0.3 kgf/mm.sup.2. 2. The radiation image storage panel of claim 1, wherein the modulus of elasticity of the thermoplastic elastomer is in the range of 0.001 to 0.1 kgf/mm.sup.2. 3. The radiation image storage panel of claim 1, wherein the thermoplastic elastomer has a tensile strength in the range of 0.1 to 20 kgf/mm.sup.2. 4. The radiation image storage panel of claim 1, wherein the thermoplastic elastomer has a tensile elongation in the range of 10 to 2,000%. 5. The radiation image storage panel of claim 1, wherein the thermoplastic elastomer is selected from the group consisting of polystyrene, polyolefin, polyurethane, polyester, polybutadiene, ethylene-vinyl acetate copolymer, poly(vinyl chloride), natural rubber, fluorinated rubber, polyisoprene, chlorinated polyethylene, styrene-butadiene rubber, and silicon rubber. 6. The radiation image storage panel of claim 1, wherein the thermoplastic elastomer is polyurethane elastomer.
