Silver halide photographic materials with higher sensitivity and less fogging having at least one silver halide emulsion layer over a photographic base or support wherein the emulsion of said emulsion layer substantially contains core/shell-type silver halide grains or core/shell-type monodisperse silver halide grains, core portion of said grain containing silver iodide in a greater amount than that contained in shell portion of said grain and said emulsion is subjected to chemical ripening in the presence of a labile selenium compound, optionally with coexistence of a silver halide solvent, and said emulsion may contain further a specific phenol compound.

Silver halide photographic materials

A method for the formation of a dye image. A silver halide color photographic light-sensitive material, having a support, component layers which are provided on the support and which have a swelling degree below 250 in the alkaline bath and components including an aromatic primary amine color developing agent or a precursor thereof, a nondiffusing yellow coupler, a nondiffusing magenta coupler and a nondiffusing phenolic cyan coupler having a substituted or unsubstituted acylamino group at the second and fifth positions thereof, is color developed in an alkaline bath. The material is then processed in a bleach-fixing bath.

Method for the formation of a dye image

A method of forming dye images by processing a photographic material containing imagewise distributed catalyzer substance in the presence of hydrogen peroxide, a coupler and certain aromatic primary amine compounds.

Forming method of a dye image

The present invention discloses a process for forming a color dye image in an image receiving layer by diffusion transfer from a light sensitive element containing a diffusible dye developer and a silver halide emulsion which has been imagewise exposed. The exposed light sensitive element is subjected to an alkaline processing solution to transfer the dye developer to an image-receiving layer of an image receiving element to produce a color dye image. The alkaline processing solution thus used should contain a compound of the following general formula: ##STR1## wherein R.sub.1 represents hydrogen, methyl, ethyl, methoxy or hydroxymethyl and R.sub.2 represents hydrogen, methyl or ethyl.

Color diffusion transfer process using benzyl alcohol and derivatives

An improved process for forming a dye image in an image receiving layer of a film unit containing a light-sensitive element and an image receiving element by incorporation therein of a compound represented by the formula ##STR1## WHEREIN R.sub.1 and R.sub.2 individually represent lower alkyl, and n is 3.
