A silver halide photographic light sensitive material is disclosed, comprising a support having on the support a silver halide emulsion layer comprising silver halide grains, wherein at least 50% of the total grain projected area is accounted for by tabular grains having an aspect ratio of 2 or more, at least one of subbing layers provided on both sides of the support comprising colloidal tin oxide sol.

Silver halide photographic light sensitive material

An improvement in silver halide photographic light-sensitive materials having at least one silver halide emulsion layer on a support is disclosed. The improvement is that chemically sensitized silver halide grains contained in at least one of the emulsion layers have a distinct stratiform structure having substantially two parts comprising an inside core part and a shell part of the uppermost layer, wherein the inside core part of said grains is composed of silver halide containing 10 to 45% by mol of silver iodide, the shell part of the uppermost layer of the grains is composed of silver halide containing 5% by mol or less of silver iodide, and the emulsion containing silver halide grains having the distinct stratiform structure have an average silver iodide content of 7% by mol or more. The materials have high sensitivity, low fog and excellent graininess.

Silver halide photographic light-sensitive materials

A silver halide color photographic sensitive material comprising a support having provided thereon a plurality of silver halide emulsion layers having sensitivity in different spectral regions, wherein at least one of said layers comprises a plurality of emulsion layers having different sensitivities and containing at least one kind of substantially monodisperse silver halide grains, with at least one of said emulsion layers having different sensitivities substantially comprised of silver bromoiodide grains containing at least 4 mol% silver iodide and the iodide contents in said emulsion layers being such that an emulsion layer having a maximum sensitivity contains more iodide than that of an emulsion layer having the second highest sensitivity. This silver halide color photographic sensitive material provides a wider exposure latitude and makes constant development possible without being influenced by the processing time for color development.

Photographic elements having at least one light-sensitive layer and at least one layer having polymeric matte particles surrounded by a layer of colloidal inorganic particles.

Photographic light-sensitive elements

A closure member for an electrical activating assembly of the type to be installed in an electrical wire distributing floor structure. The closure member has an access port assembly supported for movement between an open position wherein wires may egress from the closure member, and a closed position. The access port assembly incorporates a resilient filler strip formed from heat resistant material. The filler strip is pre-slit to provide effective sealing around egressing wires independent of the diameter of the wire.

Closure member for an electrical activating assembly

A method for preventing adhesion in a photographic light-sensitive material comprising a support having thereon at least one silver halide light-sensitive emulsion layer which comprises providing, as an outermost layer on at least one side thereof, a layer containing gelatin with the amount of gelatin coated being about 0.2 to about 0.8 g/m 2 and containing finely divided particles of a matting agent having an average particle size of about 0.1 to about 10 microns.

Method for preventing adhesion of silver halide photographic light-sensitive material

PURPOSE: To prevent adhesion without impairing physical properties, such a-stransparency or dimentional resistance after processing and photographic properties, by specifying the gelatin coating amount on a surface layer and the means size of fine particles contained COPYRIGHT: (C)1978,JPO&Japio

Adhesion preventing method for silver halide photographic material

L'invention concerne l'amelioration des proprietes physiques des materiaux photographiques. Pour eviter l'adherence d'un materiau photographique comportant un support enduit d'au moins une couche d'emulsion a l'halogenure d'argent, on applique sur au moins un des cotes du support, une couche externe gelatineuse contenant 0,2 a 0,8 g par m**2 de gelatine, et renfermant un agent de matage en fines particules, de dimension moyenne comprise entre 0,1 et 10 microns. On reduit ainsi l'adherence sans nuire a la transparence du film apres developpement.
