Abstract: A silver halide color photographic light-sensitive material is disclosed, which is improved in the color forming efficiency, the color reproducibility and the resistivity of color image against heat and humidity. The photographic material comprises a silver halide emulsion layer which contains a pyrazoloazole type cyan coupler having a group represented by Formula I which is directly bonded to the azole ring of the pyrazoloazole coupler:--(X.dbd.Y)n--R.sub.1 (I)wherein X and Y each is a substituted or unsubstituted methine group or a nitrogen atom; R.sub.1 is a hydrogen atom or a substituent; and n is an integer of 1 or 2, provided that two of Xs and two of Ys may be the same or different from each other when n is 2, and two of either X, Y and R.sub.1 are allowed to be bonded each other to form a ring other than benzene ring.

Abstract: A method for forming an image which comprises developing an imagewise exposed silver halide color photographic material with a color developer containing at least one aromatic primary amine color developing agent, wherein said silver halide color photographic material contains a silver chlorobromide emulsion having an average silver bromide content of from 0.1 to 10 mol % and containing substantially no iodide in at least one layer thereof, at least said silver chlorobromide emulsion containing a gold compound, and said color developer contains from 3.5.times.10.sup.-2 to 1.5.times.10.sup.-1 mol/l of chloride ion and from 3.0.times.10.sup.-5 to 1.0.times.10.sup.-3 mol/l of bromide ion.

Abstract: The low intensity reciprocity failure characteristics of a silver halide emulsion are improved, without significant reduction of high intensity speed, by incorporating iridium ion into the silver halide grains after or toward the end of the precipitation of the grains in such a way that iridium is below the surface of the grains.

Abstract: There is provided a silver halide photographic light-sensitive material comprising a support and photographic layers containing at least one silver halide emulsion layer thereon. At least one silver halide emulsion layer contains a silver halide grains having a silver chloride content of not less than 90 mol % and silver bromide content of not less than 0.05 mol % and at least one photographic layer contains a specific oxanol dye. The silver halide photographic light-sensitive material is suitable for rapid processing and excellent in image-sharpness.

Abstract: Hollow silver halide grains and a process for their preparation are described. The hollow grains have high surface area/volume ratio and enhanced light absorption.

Abstract: A light-sensitive photohardenable composition comprising a reducing agent, a light-sensitive silver halide, a polymerizable compound, and a coumarin or a ketocoumarin.

Abstract: Color photographic silver halide material in which at least one layer contains a silver halide emulsion with 95 to 100 mol % of chloride which has been optimally ripened with a combination of at least one sulphur ripening body and at least one compound of the formula ##STR1## in which R.sub.1, R.sub.2 and R.sub.3 denote, independently of one another, hydrogen or alkyl, and X.sup..crclbar. denotes an anion, combines excellent sensitivity with low fog and steep gradation, particularly in the threshold and shoulder region.

Abstract: A radiographic element is disclosed which exhibits high covering power, reduced crossover without emulsion desensitization, reduced wet pressure sensitivity, and can be fully processed in a rapid transport processor in less than 90 seconds. The radiographic is comprised of tabular grain emulsion layers on opposite sides of a transparent film support and processing solution decolorizable dye particles in hydrophilic colloid layers interposed between the emulsion layers and the support. Hydrophilic colloid on each side of the support is in the range of from 35 to 65 mg/dm.sup.2, with the interposed layer containing hydrophilic colloid in the amount of at least 10 mg/dm.sup.2.
