ABSTRACT:
A heat-developable color light-sensitive material comprising a support having thereon at least a light-sensitive silver halide, a binder, a dye releasing redox compound which is capable of reducing the light-sensitive silver halide and is capable of reacting with the light-sensitive silver halide by heating to release a hydrophilic dye and a salt of an alkylcarboxylic acid having a triple bond between the .alpha.-position carbon atom and the .beta.-position carbon atom with an organic base as a base precursor.
The heat-developable color light-sensitive material containing the novel base precursor has good stability during preservation and provides a color image having a high color density and low fog in a short time by a simple procedure. A method of forming a color image using the heat-developable color light-sensitive material is also disclosed.
