The present invention refers to an ink-jet recording material comprising a support, and at least one ink receiving porous layer coated on the support, wherein at least one porous layer comprises, dispersed therein, an organic solvent having a logP value higher than 2.00, an antifading compound, a non-ionic surfactant having low EDLB, an anionic surfactant, and a carboxylic derivative.

Ink-jet recording material

Silver halide multilayer color photographic material

Light-sensitive silver halide color photographic elements containing 2-equivalent 5-pyrazolone magenta coupler and colored magenta coupler

Silver halide color photographic light-sensitive elements having improved image quality

Silver halide photographic element comprising a support having coated thereon red-, green- and blue-sensitive silver halide emulsion layers comprising, respectively, cyan, magenta and yellow dye-forming couplers, wherein the blue-sensitive emulsion layer comprises at least two blue-sensitive emulsion layers, the uppermost of which has the highest-sensitivity and the lowermost of which has the lowest sensitivity, characterized in that the uppermost highest sensitivity blue-sensitive silver halide emulsion layer comprises a yellow dye-forming coupler and a cyan dye-forming coupler.

Silver halide photographic elements having improved sensitivity

A photothermographic element comprising a support bearing at least one heat-developable, photosensitive, image-forming photothermographic emulsion layer comprising:

Chromogenic leuco redox-dye-releasing compounds for photothermographic

Photothermographic elements capable of producing a high density yellow or magenta image upon image-wise exposure and thermal development at a relatively low temperature and for a short period of time are described. The photothermographic elements of the invention comprise coated on a support base at least one light-sensitive emulsion layer comprising (a) a leuco dye reducing reducing agent, (b) a photosensitive silver halide, (c) an organic silver compound capable of being reduced by the leuco dye reducing agent, and (d) a binder; wherein the leuco dye reducing agent thereto comprises a chromogenic yellow or magenta leuco dye compound. The photothermographic elements of the invention may be used to obtain yellow and magenta images of suitable density in single color or multicolor photothermographic articles. At the same time the chromogenic leuco dye is stable enough not to be oxidized by oxygen of the air or by simple heating and to limit the fog formation after development.

Yellow and magenta chromogenic leuco dyes for photothermographic elements

A silver halide photographic material having at least one silver halide light-sensitive emulsion layer on at least one side of a support, wherein said silver halide emulsion layer comprises tabular silver halide grains having a grain thickness of 0.3 .mu.m or less and accounting for at least 50% of the total projected area, and a phthalocyanine blue pigment having a maximum absorption wave length of from 640 to 700 nm is present in said silver halide emulsion layer and/or in another hydrophilic layer of the photographic material.

Silver halide photographic material with reduced fog and improved

Phothermographic material capable of producing a high density cyan image upon image-wise exposure and thermal development at a relatively low temperature and for a short period of time. The photothermographic material of the invention comprise coated on a support base at least one light-sensitive emulsion layer containing: (a) a binder; (b) a silver source material; (c) a light sensitive silver halide in catalytic proximity to said silver source material, wherein said emulsion layer or an adjacent layer thereto comprises a chromogenic cyan leuco dye. The photothermographic material of the invention may be used to obtain good cyan image of suitable density in single color or multicolor photothermographic articles. At the same time the chromogenic leuco dye is stable enough not to be oxidized by oxygen of the air or by simple heating and to limit the fog formation after development.
