    摘要: A light-modulating, electrically responsive privacy screen includes a transparent substrate and an electrically conductive layer formed over the substrate. The privacy screen further includes a light-modulating layer disposed over the electrically conductive layer and including at least one dispersible light-modulating material and coalescence limiting material into which the dispersible light-modulating material(s) is provided so that such dispersible light-modulating material coalesces to form a set domains having at least two optical states, the first optical state being present in the absence of an electrical field and the second being caused by the application of an electrical field and wherein one of the optical states cause the light-modulating layer to be transparent and the other optical state causes the light-modulating layer to restrict a user viewing through the privacy screen and thereby provide an appropriate level of privacy.

    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.

    摘要: A process for forming a silver halide photographic emulsion is disclosed comprising precipitating silver halide grains in an aqueous dispersing medium to which has been added silver and halide salt solutions while agitating the dispersing medium, wherein the precipitation is done in the presence of an antifoamant which comprises a hydrophobic group containing nonionic mono- or di-saccharide compound having an HLB number of between 2 and 12. The antifoamant material may be delivered to the aqueous dispersing medium as a small particle dispersion, made with the same peptizer used for manufacturing the emulsion or another stabilizer. A further embodiment of the invention is directed towards a silver halide photographic material comprising a support upon which is coated at least one light sensitive silver halide emulsion layer, comprising a silver halide emulsion precipitated in accordance with the described process.
