Patent Number: 062460633
Section: claims

1. A radiation image storage panel having a phosphor layer of a stimulable phosphor, and a surface protective film provided thereon, wherein the surface protective film exhibits scattering with a scattering length of 5 to 80 .mu.m observed at a main wavelength of stimulated emission from the stimulable phosphor. 2. The radiation image storage panel of claim 1, wherein the scattering length is in the range of 10 to 70 .mu.m. 3. The radiation image storage panel of claim 1, wherein the surface protective film comprises light-scattering fine particles dispersed in a resin. 4. The radiation image storage panel of claim 3, wherein the light-scattering fine particles have a refractive index of at least 1.6 and a particle size of 0.1 to 1.0 .mu.m. 5. The radiation image storage panel of claim 4, wherein the light-scattering fine particles have a refractive index of at least 1.9 and a particle size of 0.1 to 0.5 .mu.m. 6. The radiation image storage panel of claim 3, wherein the surface protective film contains light-scattering fine particles in an amount of 0.5 to 10 wt. %. 7. The radiation image storage panel of claim 1, wherein the surface protective film has a thickness of 3.5 to 10 .mu.m. 8. The radiation image storage panel of claim 3, wherein the resin is a fluororesin. 9. The radiation image storage panel of claim 1, wherein the surface protective film further contains a dispersing agent.
