摘要： A silver halide photographic material comprises a support, at least one silver halide emulsion layer and at least one non-light-sensitive hydrophilic colloidal layer. The silver halide emulsion layer or the hydrophilic colloidal layer contains a colorant having the absorption maximum wavelength within the infrared region of 700 to 1,100 nm. The colorant is in the form of solid particles dispersed in the silver halide emulsion layer or in the hydrophilic colloidal layer. The solid particles cannot substantially be removed by a processing solution of the silver halide photographic material. An image forming process employing the silver halide photographic material is also disclosed.
