Photographic element with gas permeable hydrophobic layer on backing layer

A dye-fixing element to which is transferred a mobile dye to be formed or released by heat-development of a photographic element;

• wherein said photographic element comprises a light-sensitive silver halide, a hydrophilic binder and a dye providing compound for forming or releasing a mobile dye in correspondence or reverse correspondence with the amount of exposure, after or simultaneously with, imagewise exposure of said photographic element in the presence of at least one of a base and a base precursor;
• and wherein said dye-fixing element comprises a water-soluble base or base precursor in at least a dye-fixing layer or an adjacent layer(s) on one surface of a support, and has a backing layer comprising a hydrophilic binder on the other surface of said support and comprising, as the outermost layer, a gas-permeable hydrophobic layer, and said gas-permeable hydrophobic layer is an aeriferous layer containing a hydrophobic polymer.

A photographic element comprising a water-soluble base or base precursor in at least a dye-fixing layer or an adjacent layer(s) thereto on one surface of a support and a backing layer comprising a hydrophilic binder on the other surface of the support, wherein a gas-permeable hydrophobic layer is provided as the outermost layer of said backing layer, and said gas-permeable hydrophobic layer is an aeriferous hydrophobic layer comprising organic or inorganic fine grains and a hydrophobic polymer as an adhesive for said fine grains.
