Abstract: A heat-developable photosensitive material comprising a support having coated thereon at least on sensitive layer comprising (a) a binder and at least one of (b) an organic silver salt, (c) a photocatalyst, and (d) a reducing agent wherein said heat-developable photosensitive material additionally contains (e) a polyisocyanate and a process for preparing same are disclosed.

Abstract: A process for forming a subbing layer in photographic sensitive materials which comprises applying an aqueous dispersion of a copolymer consisting of at least one diolefin monomer and one or more vinyl monomers to a plastic film base in which the gel fraction of the copolymer in said aqueous dispersion is about 80% by weight or less.

Abstract: A process for producing a photographic material, which comprises dispersing, in a solution of an organic resin, a material which is incompatible with the organic resin to form a dispersion, coating the resulting dispersion on at least one side of a support to form a coated layer, and then drying the coated layer, the material dispersed being a solid at ordinary temperature and in a liquid phase during the dispersing, whereby the coated layer when dried contains solid particles dispersed therein due to solidification of the dispersed material.The present invention also provides a photographic material obtained by the above process.

Abstract: A photographic material comprising (I) a styrene-based polymer support having thereon a subbing layer which comprises a partial or complete reaction product of (a) a copolymer of styrene or vinyl acetate with maleic anhydride with (b) water or a hydroxy compound such as alcohol and (II) a photographic layer comprising a hydrophilic resin binder bearing on the subbing layer, wherein a compound containing two or more epoxy groups per molecule is contained in the subbing layer or in both of the subbing layer and the photographic layer.

Abstract: A photographic material comprising a support having thereon at least one photographic layer with the layer adjacent the support containing non-volatile or low volatile liquid droplets having smaller diameters than the thickness of the layer adjacent the support and a process for producing the photographic material.
