In heat developable photographic system of dry procedure, color images are formed by imagewise exposing and then heating a light-sensitive material comprising a support having provided thereon a light-sensitive layer containing silver halide, a binder, and a compound capable of producing or releasing, upon reduction of light-sensitive silver halide to silver at elevated temperatures, a mobile dye, as a direct or inverse function of the reduction reaction, allowing the produced or released mobile dye to migrate into a dye-fixing material having incorporated therein a hydrophilic thermal solvent and fixing the dye thereto, then separating the light-sensitive material from the dye-fixing material, with a fluorine-containing surfactant being incorporated in at least one of the uppermost layers on the contacting sides of the light-sensitive material and of the dye-fixing material. Adhesion and poor S/N ratio problems accompanied by the use of hydrophilic thermal solvents are improved by incorporating fluorine-containing surfactants into the aforesaid layers.
A process for forming a color image which comprises imagewise exposing and then heating a light-sensitive material comprising a support having provided thereon a light-sensitive layer containing silver halide, a binder, and a compound capable of producing or releasing, upon reduction of light-sensitive silver halide to silver at elevated temperatures, a mobile dye, as a direct or inverse function of the reduction reaction, allowing the produced or released mobile dye to migrate into a dye-fixing material having incorporated therein a hydrophilic thermal solvent and fixing the dye thereto, then separating the light-sensitive material from the dye-fixing material, with a fluorine-containing surfactant being incorporated in at least one of the uppermost layers on the contacting sides of the light-sensitive material and of the dye-fixing material at the interface between the light-sensitive material and the dye-fixing material, the light-sensitive material and the dye-fixing material being in contact with each other.
A process for forming a color image which comprises image-wise exposing and developing a diffusion transfer color light-sensitive element comprising a support having provided thereon, in succession, a dye-fixing material having a dye-fixing layer having incorporated therein a hydrophilic thermal solvent and a light-sensitive layer containing silver halide, a binder, and a compound capable of producing or releasing, upon reduction of light-sensitive silver halide to silver at elevated temperatures, a mobile dye, as a direct or inverse function of the reduction reaction, allowing the produced or released mobile dye to migrate into the dye-fixing material and fixing the dye thereto, then separating the light-sensitive material from the dye-fixing material, with a fluorine-containing surfactant being incorporated in at least one of the uppermost layers on the contacting sides of the light-sensitive material and of the dye-fixing material at the interface between the light-sensitive material and the dye-fixing material, the light-sensitive material and the dye-fixing material being in contact with each other.
