As we described earlier, photographic film is made up of a polymeric base onto which emulsion and gelatin layers are coated; the emulsions contain silver halide grains, oil droplets (containing coupler) and other chemicals. In this chapter we consider the process of making the solid gelatin from solution of aqueous gelatin; this process is called gelation. It proceeds by molecular cross-linking in the initial gelatin solution.
