Abstract
An improvement of a radiation image storage panel comprising a stimulable phosphor layer which comprises stimulable phosphor particles, a binder and a colorant resides in that a weight ratio of binder to phosphor particles and concentration of coloring are varied along the depth of the phosphor layer in such manner that a mean value of a weight ratio of binder to phosphor particles within 1/4 of the depth of the phosphor layer from one surface thereof is larger than a mean value of a weight ratio of binder to phosphor particles between 1/4 and 3/4 of the depth of the phosphor layer, and a mean value of a weight ratio of colorant to phosphor particles within 1/4 of the depth of the phosphor layer from the surface is smaller than a mean value of the weight ratio of colorant to phosphor particles between 1/4 and 4/4 of the depth of the phosphor layer from the surface.
