Claims
- 1. A method of forming an image comprising heating a light-sensitive material having at least a light-sensitive silver halide, a binder and 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 at a temperature of from 50.degree. C. to the boiling point of water to release a hydrophilic diffusible dye on a support after or simultaneously with imagewise exposure in the presence of water and a base and/or a base precursor to form a mobile dye and transferring the mobile dye to a dye fixing layer at the time of heating for development,
- wherein an amount of the water is in a range from 0.1 time by weight of the total coated layers included in the material relevant to the image forming method to a weight of water corresponding to the maximum swelling volume of the total coated layers, and
- the water is supplied to the light-sensitive material or the water is supplied to the dye fixing material.
- 2. A method of forming an image as claimed in claim 1, wherein the dye fixing layer is provided in the light-sensitive material.
- 3. A method of forming an image as claimed in claim 1, wherein the dye fixing layer is provided in a dye fixing material.
- 4. A method of forming an image as claimed in claim 1, wherein the base and/or base precursor is present in the dye fixing layer.
- 5. A method of forming an image as claimed in claim 1, wherein the base and/or base precursor is present in the water.
- 6. A method of forming an image as claimed in claim 5, wherein an amount of the base and/or base precursor is from 0.005 mol/l to 2 mol/l.
- 7. A method of forming an image as claimed in claim 1, wherein a pH of the layer at the time of heating is in a range from 8 to 12.
- 8. A method of forming an image as claimed in claim 7, wherein a pH of the layer is in a range from 9 to 11.
- 9. A method of forming an image as claimed in claim 1, wherein the binder is gelatin.
- 10. A method of forming an image as claimed in claim 1, wherein the light-sensitive material further contains an organic silver salt oxidizing agent.
- 11. A method of forming an image as claimed in claim 1, wherein the dye fixing layer contains a mordant for fixing the mobile dye.
- 12. A method of forming an image as claimed in claim 1, wherein the water is pure water.
- 13. A method of forming an image as claimed in claim 1, wherein the water is an aqueous solution containing the base and/or base precursor.
- 14. A method of forming an image as claimed in claim 1, wherein the water is a mixture of water and an organic solvent having a low boiling point.
- 15. A method of forming an image as claimed in claim 1, wherein the water is an aqueous solution containing a dye releasing activator, an accelerator or a hydrophilic thermal solvent.
- 16. A method of forming an image as claimed in claim 1, wherein the base is an inorganic base or an organic base.
- 17. A method of forming an image as claimed in claim 1, wherein the base precursor is a substance which releases a basic component by heat-decomposition.
- 18. A method of forming an image as claimed in claim 1, wherein an amount of the base and/or base precursor is 50% by weight or less based on the weight of the layer to be incorporated.
- 19. A method of forming an image as claimed in claim 1, wherein the heating is carried out in the presence of a hydrophilic thermal solvent.
- 20. A method of forming an image as claimed in claim 19, wherein the hydrophilic thermal solvent is present in the light-sensitive material.
- 21. A method of forming an image as claimed in claim 19, wherein the hydrophilic thermal solvent is present in the dye fixing layer and/or adjacent layers thereto.
- 22. A method of forming an image as claimed in claim 1, wherein the light-sensitive material comprises a support having thereon a light-sensitive layer containing the light-sensitive silver halide, the binder and the dye releasing redox compound.
- 23. A method of forming an image as claimed in claim 22, wherein the light-sensitive layer further contains an organic silver salt oxidizing agent.
- 24. A method of forming an image as claimed in claim 1, wherein the light-sensitive material is exposed imagewise, superposed on the dye fixing layer and subjected to the heating to transfer the mobile dye to the dye fixing layer.
- 25. A method of forming an image as claimed in claim 24, wherein the dye fixing layer is peeled apart from the light-sensitive material after the heating.
- 26. A method of forming an image as claimed in claim 24, wherein the dye fixing layer contains the base and/or base precursor.
- 27. A method of forming an image as claimed in claim 26, wherein the dye fixing layer further contains the water.
