    摘要： The present invention refers to an ink jet receiving sheet for ink-jet printers comprising a support and at least two ink receiving layers, wherein the ink receiving layer farthest from the support comprises a first non-ionic surfactant having a dynamic surface tension lower than or equal to 27 dyne/cm2, and in that the other ink receiving layer(s) comprise(s) a second non-ionic surfactant having a dynamic surface tension higher than or equal to 30 dyne/cm2. The ink jet receiving sheet of the invention provides minimum bleed, no mottle and good glossiness.

    摘要： A process for preparing a monodispersed silver halide grain emulsion characterized in that said process comprises the steps of:(a) forming silver halide nuclei with single jet precipitation by adding a watersoluble silver salt solution to a reaction vessel containing a water-soluble halide salt solution in a hydrophilic colloid at a pCl of from 1.0 to 2.0 and at a temperature lower than 80.degree. C., said water-soluble silver salt solution being added in an amount of from 0.1 to 15% by weight of silver relative to the total silver,(b) stabilizing said silver halide nuclei to seed crystals for at least six minutes at a temperature lower than 80.degree. C. and at pCl of from 1.5 to 3.0 by Ostwald ripening, and(c) growing said seed crystals by double jet precipitation of silver and halide salt solutions at a constant chloride ions excess of from 30 to 70% mol and a temperature lower than 80.degree. C.

    摘要： In a reversal process for the formation of color photographic images which consists of a black and white development (first development) to obtain a first negative image, followed by exposure and/or uniform fogging of the residual silver halide and a further processing (including a second color development), to obtain a second visible (in transparency) color positive image, of a silver halide color multilayer material which comprises, coated on a support base, one or more red-sensitive silver halide emulsion layers associated with dispersed non-diffusing hydrophobic cyan couplers, one or more green-sensitive silver halide emulsion layers associated with dispersed non-diffusing hydrophobic magenta couplers and one or more blue-sensitive silver halide emulsion layers associated with dispersed non-diffusing hydrophobic yellow couplers, the improvement which consists of the reversal development of said magenta-forming layer being performed in the absence of a significant presence of oil.
