摘要： PROBLEM TO BE SOLVED: To obtain an image excellent in sharpness with high sensitivity in a short time without contaminating a small amt. of water used for development by superposing a silver halide photosensitive material contg. a dye mordanting compsn. which liberates a hydrophilic dye in a heat development on a processing sheet, carrying out heat development and peeling the processing sheet. SOLUTION: A photosensitive material contg. photosensitive silver halide, a binder and a dye mordanting compsn. which liberates a hydrophilic dye in a heat development on the substrate is imagewise exposed. After or during this exposure, the photosensitive material is superposed on a processing sheet coated with a binder and a mordant in the presence of a reducing agent, a base or its precursor and water, they are heated and an image is obtd. on the photosensitive material by peeling the processing sheet. A mordant as a constituent of the dye mordanting compsn. is a polymer having repeating units of an ethylenically unsatd. monomer having a proton added ammonium structure (salt).

摘要： PURPOSE: To provide a method for producing an image receiving material having a high film surface pH using a low-pressure coating soln. at the time of producing an image receiving material contg. a complex compd. generating a base by the complexing reaction with a basic metal compd. such as zinc hydroxide sparingly soluble in acid. CONSTITUTION: An image receiving material having a base precursor liberating a base by a hydrophilic binder and a complexing reaction on a substrate is produced. In this case, a coating soln. to form at least one hydrophilic binder- contg. layer on the substrate on the side contg. a base precursor of the substrate contains a carbonate, and the pH of the film surface is controlled to >=9 after coating and drying. The pH of the film surface after drying is more preferably controlled to >=9.5 to promote the heat developability and transferability of the image receiving material. The effect of the carbonate is enhanced when the maximum pKa of the pKa of the base precursor is controlled to >=8. Besides, the pH of the coating soln. contg. the carbonate is preferably controlled to
