An ink-jet recording sheet, comprising a support having thereon a porous ink receiving layer, the porous ink receiving layer including inorganic particles, a hydrophilic binder and a polymer, wherein the polymer has a plurality of carbon-carbon unsaturated bonds, provided that the unsaturated bonds are non-aromatic; the polymer has a recurring unit derived from butadiene or isoprene.

Ink-jet recording sheet

An ink-jet recording sheet comprising a support having thereon in the following order: (i) a first ink absorbing layer comprising gelatin and a first cationic polymer; and (ii) a second ink absorbing layer comprising gelatin and a second cationic polymer, wherein the first cationic polymer has a larger ink absorption ratio A than the second cationic polymer, the ink absorption ratio A being defined by the following equation: A (%)&equals;((an optical density of a print after immersion in water)/(an optical density of a print before immersion in water))&times;100.

Ink-jet recording medium

A silver halide color photographic light-sensitive material is disclosed. The silver halide color photographic light-sensitive material is exposed by scanning with a light beam having a pixel size of r &mgr;m for a time of not more than 10 seconds per pixel, and developed wherein the difference of a hwb value in thus obtained image in each of the color-forming layers and the value of r is within the range of form 0 to 50, in which the hwb is the half band width in &mgr;m of a line reproducing the line having a width of one pixel.

Image forming method

A silver halide photographic light sensitive material IS DISCLOSED, comprising a support having thereon a yellow dye image forming layer, a magenta dye image forming layer and a cyan dye image forming layer, wherein when the photographic material is subjected to exposure of not more than 10 sec. per pixel element and further to color developing to form yellow, magenta and cyan images, a variation at multiple exposure, based on non-multiple exposure, of an average gradation, which is a slope that connects two pints corresponding to densities of 0.5 and 1.5 on a characteristic curve of each of the yellow, magenta and cyan images, is not more than 10%.

Silver halide photographic light sensitive materials and image forming method by use thereof

A silver halide emulsion is disclosed, containing silver halide grains having a chloride content of not less than 90 mol %, wherein the silver halide grains each are internally doped with compound (A), compound (B) and compound (C); compounds (A) and (B) each meeting specified requirements and compound (C) being an iridium compound.

Silver halide emulsion

The image forming method comprising the steps of subjecting a silver halide photographic light-sensitive material comprising an yellow image forming layer, a magenta image forming layer and a cyan image forming layer to scanning exposure with a light beam so that an exposure time is not more than 10,second per pixel, and developing the photographic material by a color developer, wherein the maximum exposure amount (E,) is controlled by an output of a calibration patch, and a difference between the logarithm of the exposure amount necessary to give a density of 0.3 and the logarithm of E,is within the range of from 0.35 to 0.6 in each of the yellow, magenta and cyan image forming layers.

Silver halide color photographic light sensitive material and image forming method by use thereof

An image forming method of a silver halide light sensitive photographic material including a color image forming layer containing a silver halide emulsion and a dye providing material is disclosed, the image forming method comprising the steps of developing the exposed photographic material with a first processing solution and subjecting the developed photographic material to amplification with a second processing solution, wherein the first processing solution contains a black-and-white developing agent and a color developing agent.
