PURPOSE:To obtain a sharp image high in density and low in fog by forming 2 photosensitive layers containing photosensitive silver halide and a dye donor on a supporting body and a nonphotosensitive interlayer containing a high boiling solvent and a thermal solvent between said layers. CONSTITUTION:The at least 2 photosensitive layers formed on the supporting body contains at least the photosensitive silver halide and the dye donor and at least one nonphotosensitive interlayer is formed between them. At least one of the interlayer contains the high boiling solvent and the thermal solvent. Said high boiling solvent has an inorganic fraction/organic fraction ratio of <=0.7, preferably, 0.1-0.7, a boiling point of preferably, >=200 deg.C, and a melting point of <=80 deg.C, and it is a compound liquid at 25 deg.C, and the thermal solvent is a compound for promoting heat development and/or heat transfer, and it has an inorganic fraction/organic fraction ratio of, preferably, >=0.7 and <5.0, especially, >=0.7 and <=2.0. |
