Abstract: Silver halide photographic material comprising finely divided solid spherical polymer beads having an average particle size between about 0.1 and about 10 .mu.m and having a glass transition temperature of at least 40.degree. C. The polymer beads are prepared by a one step reaction in an aqueous reaction medium whereby the polymer beads are formed by the simultaneous reaction of1) a silane monomer comprising an .alpha.,.beta.-ethylenically unsaturated group,2) at least one .alpha.,.beta.-ethylenically unsaturated monomer, different from the silane monomer, capable of forming a polymer that is soluble in the monomer(s) present in the aqueous solvent mixture but which is insoluble in water,3) a free radical-forming polymerization initiator that is soluble in the aqueous solvent mixture, and4) a graft-polymerizable polymer containing hydrophilic groups, and capable of forming a graft polymer that remains soluble in the aqueous reaction mixture.

Abstract: A silver halide photographic material is provided comprising at least one silver halide emulsion layer and an outermost layer comprising an hydrophillic binder and polymeric spacing particles characterized in that(i) the outermost layer has a thickness between 0.3 to 0.9 pm and(ii) the polymeric spacing particles comprise at the surface alkali metal carboxylate or sulphonate groups equivalent to an acid value greater than 1.0 mg KOH per 1 g of polymeric spacing particles. In a preferred embodiment the said spacing particles have a volume average diameter (d.sub.v50) that is 5 to 30 times larger than the thickness of the outermost layer.

Abstract: The present invention provides a method of hardening a proteinaceous layer of a photographic silver halide element by incorporating a modified dextran in said proteinaceous layer, said modified dextran being the reaction product of dextran and an alkyl haloformate, a substituted alkyl haloformate, an aryl haloformate, or a substituted aryl haloformate. The invention also provides a photographic element comprising a said reaction product in at least one proteinaceous silver halide emulsion layer and/or in another proteinaceous layer coated thereon.
