    摘要： Spectral properties of dye images produced from low silver halide coverage materials are improved by using dyes which are formed in the magenta, yellow and cyan image dye-forming units. These dyes have certain spectral characteristics, as determined by their unwanted absorptions, in combination with certain silver halide emulsion grain characteristics in each emulsion layer. In particular, reduction of unwanted absorptions can be achieved either with couplers per se which meet these characteristics or by the use of certain high-boiling solvents in the coupler dispersions at preferred levels.

    摘要： The invention provides an aqueous inkjet ink composition comprises a polymeric compound comprising discrete particles responsive to an external stimulus, and a functional material, wherein the functional material may be incorporated as part of the polymeric particles, the particles causing the composition to have a first rheological state and a different second rheological state in response to a stimulated change in conditions, the first rheological state being associated with a first lower viscosity of the composition, wherein the particles have a first lower volume, enabling the composition to pass through an inkjet printhead orifice and the second rheological state being associated with a second higher viscosity of the composition, wherein the particles have a second higher volume, enabling immobilisation of droplets of the composition on a substrate. The inkjet composition is particularly useful in a continuous inkjet printing system for printing onto a wide range of surfaces including impermeable surfaces.

    摘要： A hydrophobically capped oligomeric acrylamide or pyrrolidone is employed as a dispersant for hydrophobic materials in an aqueous medium containing a hydrophilic colloid, e.g. gelatin. The hydrophobic materials include photographic addenda such as color couplers or solid particle dyes. Preferred dispersants have the general formula R—L—T   (1) or in which R, R1 and R2 are each independently selected from aliphatic hydrocarbyl, aryl-(aliphatic hydrocarbyl) and (aliphatic hydrocarbyl)-aryl groups, L is a sulphur atom or a linking group that contains a sulphur atom attached to the T group, and T is a hydrophilic oligomeric group obtained by the oligomerisation of one or more vinyl monomers having an amido function.
