Radiation image storage panel
View Patent ↗A radiation image storage panel is composed of a phosphor layer containing an energy-storing phosphor and a light-reflecting layer contains particles of light-reflecting material, a binder, and a surface-treatment agent.
1. A radiation image storage panel which comprises a support, a light-reflecting layer, a phosphor layer containing an energy-storing phosphor, and a transparent protective layer; wherein the light-reflecting layer comprises, at least, particles of light-reflecting material having a mean size of 0.1 to 2.0 μm, a binder, and a coupling agent selected from the group consisting of an aluminum coupling agent, a titanate coupling agent and a silane coupling agent, in an amount of 0.05 to 5 wt % based on an amount of the particles of light-reflecting material, a weight ratio of the binder to the particles of light-reflecting material being in the range of 1/10 to 1/50.
2. The radiation image storage panel of claim 1 , wherein the light-reflecting material is a white pigment.
3. The radiation image storage panel of claim 1 , wherein the light-reflecting material is at least one white pigment selected from the group consisting of alumina, yttrium oxide, zirconium oxide and titanium oxide.
4. The radiation image storage panel of claim 1 , wherein the light-reflecting layer shows a scattering length of 5 μm or less to a stimulating light which excites the energy-storing phosphor.
