摘要： A radiographic image forming process comprises treating a negative type-silver halide photegraphic light-sensitive material comprising a support bearing on each side thereof a constituent layer containing,
a) light-sensitive silver halide particles, b) metallic salt particles whose surfaces are retarded to be soluble by a dissolution retarder while said metallic salt particles themselves are more readily soluble then said light-sensitive silver halide particles, and which is non-light-sensitive, and c) physical development nuclei, with a processing solution after exposing imagewise to radiation rays in combination with a fluorescent intensifying screen. Problems arising from cross-over phenomena, i.e. images on one side produced by light transmission through the support, can be avoided by incorporating within the constituent layers;
d) at least one water-soluble dye whose maximum absorption in an aqueous solution is from 400 to 600 nm, or a compound comprising said water-soluble dye coupled to a non-diffusive mordant, and employing in the processing solution: i) at least one reducing agent, and ii) at least one substance capable of dissolving the undermentioned metallic salt particles.
