<p>PURPOSE:To prevent unequal transfer and the curling at the time of low humidity by providing a back layer consisting of a hydrophilic binder on the other surface of a base provided with a layer contg. a hydrophilic low-molecular compd. and providing an air permeable hydrophobic layer on the outermost layer thereof. CONSTITUTION:The air permeable hydrophilic layer includes three types; an air permeable porous layer contg. a hydrophobic polymer, a hydrophobic layer contg. org. or inorg. fine particles and a hydrophobic polymer as the adhesive for these fine particles and a hydrophobic thin film contg. a hydrophobic polymer having steam permeability. A base or base precursor is incorporated into at least the dye fixing layer of the photosensitive element contg. at least a photosensitive silver halide, hydrophilic binder and a dye donative compd. releasing a diffusive dye by corresponding or reverse corresponding to an exposure or the adjacent layer thereof and the back layer is provided on the opposite side thereof. Further, the air permeable hydrophobic layer is provided on the outermost layer thereof. The preservable property of the laminated layers of the dye fixing element used for heat development is improved in this way.</p> |
