摘要： A silver halide light-sensitive material containing at least silver halide grains, a dispersion medium, an antifoggant, and a hardening agent, wherein said antifoggant is an antifoggant having a reactive substituent capable of reacting with a functional group of the dispersion medium to form a covalent bond after adsorption on the silver halide grains and/or an antifoggant previously covalently bonded to the dispersion medium. The antifoggant is immobilized in a light-sensitive material while exerting its antifogging activity and is not therefore dissolved into a developing solution.
