Abstract
There is disclosed a light-sensitive silver halide photographic material comprising at least one hydrophilic colloid layer containing microcapsules encapsulating a photographic treating reagent coated with a wall material, which can be dissolved at pH 7 or higher, provided on a support.
The microcapsules of the present invention, can be effectively employed in a one-bath treatment method for forming a dye image. The bath is highly stable and the resulting images have extremely high color density.
