Abstract: Color silver halide photographic elements having a yellow dye image-forming unit comprises at least one blue-sensitive silver iodobromide emulsion layer that has silver iodobromide grains. The silver iodobromide grains have initially associated therewith at least two blue spectral sensitizing dye layers comprising: (a) an inner dye layer adjacent the silver iodobromide grains comprising at least one anionic blue spectral sensitizing Dye 1, and (b) an outer dye layer adjacent to the inner dye layer comprising at least one cationic blue spectral sensitizing Dye 2. Dye 2 absorbs light at equal or higher energy than Dye 1. The maximum energy emission wavelength of Dye 2 overlaps but is not exactly corresponding to the maximum energy absorption wavelength of Dye 1. The silver iodobromide grains also have initially associated therewith an amine borane compound and a thiosulfonate compound.

Abstract: This invention relates to a silver halide photographic material comprising at least one silver halide emulsion comprising silver halide grains having associated therewith: (a) a first dye (Dye 1) that is a cyanine dye capable of spectrally sensitizing a silver halide emulsion and that has at least one anionic substituent; and (b) a second dye (Dye 2) that is not a cyanine dye and that has at least one cationic substituent. Dye 2 has a log P, excluding any counterion, of less than 4.00 and greater than 1.00 or Dye 2 is represented by a dye of formula II as described herein.

Abstract: (F.sub.2.sup.+).sub.A color centers can be produced in additively-colored KI:Li or RbI:Li crystals provided that the material is colored in a nitrogen-free atmosphere. Copious (F.sub.2.sup.+).sub.A centers are produced in lithium-doped KI:Li or RbI:Li crystals using a procedure in which the crystals are grown, additively colored, and annealed in an argon ambient; and optically excited at successively-lower temperatures with a light of a wavelength readily absorbed by the crystal situated in a vacuum.

Abstract: The present invention is directed to a method of inhibiting the formation of coke during the elevated temperature processing of hydrocarbons. The method generally comprises adding to the hydrocarbon an effective amount of an ammonium borate, particularly ammonium biborate and ammonium pentaborate. Preferably, the ammonium borates are in a glycollic solvent or water.
