Abstract: Photographic silver halide materials containing aryl hydrazides as defined and novel aryl hydrazides with a cationic group in the acyl radical enables the preparation of photographic materials that can be developed rapidly to ultrahigh contrast at a relatively low pH value. The photographic materials are useful in reprography, particularly screening for halftone images.

Abstract: A process of developing exposed silver halide elements comprises developing said element in a developer in the presence of a development accelerator compound as defined. The development accelerator compounds include pyridinium, or pyridinium and and imidazolium compounds. The process is applicable to standard and hydrazine-containing films and to hydroquinone and/or ascorbic acid-based developers. The development accelerator may be incorporated into the developer or into the silver halide emulsion.

Abstract: An aqueous ink jet ink comprises an aqueous carrier medium, a colorant and at least one alkylpolyol ether cosolvent selected from the group of alkyl-bis-oxyalkyldiols, olefinic oxyalkyl diols, alkyl-tris-oxyalkyldiols and alkyl-tetrakis-oxyalkyldiols exhibit rapid drying, excellent image definition, are storage stable, have low odor and have excellent decap properties.

Abstract: A novel group of fluoroacetylphenyl hydrazines useful in insuring rapid-access processing of lithographic film elements is described. These hydrazines not only will produce good dot quality under conditions of rapid-access processing, but can be used a lower pH than conventional, prior art elements and will produce lower fog.

Abstract: Aqueous ink jet ink compositions comprising an aqueous carrier medium, a colorant, and cosolvents which are selected amide, sulfonamide, urea and thiourea derivatives of polyoxyalkyleneamines having a solubility in water of at least 4.5% at 25.degree. C., have high optical density, excellent print quality, excellent dispersion stability, and resist film formation on resistors without adversely affecting decap time or crusting.

Abstract: Substituted diaminedithio-containing compounds useful for improving the speed of a silver halide emulsion are described. These compounds can be added in small amounts to the emulsion preferably after the emulsion has been chemically sensitized and just prior to coating. Fog levels are not greatly affected which is surprising since conventional sensitizers generally do increase the fog level.

Abstract: Aqueous ink jet ink compositions comprising an aqueous carrier medium, a colorant, such as a pigment dispersion or dye, and a nitrogen-containing organic cosolvent having a solubility in water of at least 4.5 % at 25.degree. C., exhibit freedom from plug formation and excellent storage stability.

Abstract: Presence of a ring opening monomer polymerizable by free radical sigma-bond cleavage in a photopolymerizable composition improves volume reflection holograms prepared from the composition.

Abstract: Electrostatic liquid developer consisting essentially of(A) nonpolar liquid having Kauri-butanol value less than 30, present in major amount,(B) at least one thermoplastic resin having an average particle size by area of less than 10 .mu.m, and(C) at least one glyceride charge director as defined. Optionally a colorant and a charge adjuvant can be present. The elastrostatic liquid developer is useful in copying, making proofs, including digital color proofs, lithographic printing plates, resists and medical hardcopies.

Abstract: A novel process for the preparation, for example of gelatino silver chloride and silver bromochloride grains with modified tabular crystal habit is described. These grains are prepared using standard single jet (SJ) or balanced double jet (BDJ) techniques, said preparation occurring in the presence of a modifying amount of an aminoazapyridine as defined and a suitable binder to form well-developed, sensitive tabular elements with a median grain volume in the range of 0.005 to 0.50 .mu.m.sup.3.
