Abstract: Silver halide photographic element comprising a support having coated thereon red-, green- and blue-sensitive silver halide emulsion layers comprising, respectively, cyan, magenta and yellow dye-forming couplers, wherein the blue-sensitive emulsion layer comprises at least two blue-sensitive emulsion layers, the uppermost of which has the highest-sensitivity and the lowermost of which has the lowest sensitivity, characterized in that the uppermost highest sensitivity blue-sensitive silver halide emulsion layer comprises a yellow dye-forming coupler and a cyan dye-forming coupler.

Abstract: The present invention provides a photosensitive color proofing article incorporating an antihalation effective amount of one or more antihalation dyes of the general formula (I) shown below: ##STR1## wherein: Z is an oxygen atom, NH, or NR; R is an alkyl group of 1 to 12 carbon atoms or a hydrogen atom; R.sup.1 represents a perfluoroalkylsulfonyl group of 1 to 12 carbon atoms or an arylsulfonyl group; and R.sup.2 represents a perfluoroalkylsulfonyl group of from 1 to 12 carbon atoms; an arylsulfonyl group; or a cyano group. The antihalation dyes of formula (I) absorb radiation within the wavelength range of from about 325 to 700 nm and preferably, from about 325 to 450 nm.

Abstract: The present invention describes a light-sensitive silver halide photographic material comprising a support and silver halide emulsion layer or layers, wherein at least one of said silver halide emulsion layers contains tabular silver halide grains having an average diameter to thickness ratio of at least 2:1 and at least one azodicarbonamide derivative.

Abstract: Blue-black color favored in medical imaging is imparted to black and white photographic emulsions by the addition of a compound of formula I or II: ##STR1## wherein: R.sup.1 and R.sup.2 independently represent one or more carbon atoms necessary to complete a 5, 6 or 7 membered ring;R.sup.3 and R.sup.4 independently represent H, alkyl or aryl groups or together represent the atoms selected from C, N, O and S necessary to complete a 5, 6 or 7 membered cyclic ring but are not both H;R.sup.5 and R.sup.6 independently represent H or alkyl or together represent the atoms selected from C, N, O and S necessary to complete a 5, 6 or 7 membered ring;X represents a bond or a divalent linking group,each Y may be the same or different and is selected from S, Se, O, and NR.sup.7, where R.sup.7 is H or alkyl of up to 5 carbon atoms, andZ is S or Se.

Abstract: Zirconium based granules are produced by the steps of forming an aqueous solution of a zirconium compound such as zirconium acetate, combining the aqueous solution with a phase stabilizer, and then heating the solution to evaporation at a temperature below about 180.degree. C. preferably below thereby forming amorphous zirconium based granules.In an alternate embodiment, an alcohol solution of a zirconium compound such as zirconium propoxide in propanol is acidified and hydrolyzed with water. The partially or fully hydrolyzed zirconium complex is mixed with a phase stabilizer to form a homogeneous solution. The solution is then subjected to evaporation at a temperature below about 180.degree. C. or below to form amorphous zirconium based granules.Zirconia fibers are produced by making aqueous solution of the amorphous zirconium based granules containing the phase stabilizer to the desired viscosity, fiberizing the solution, and finally converting the fibers under appropriate conditions.

Abstract: A process for making a fibrous mat includes the steps of (a) combining (i) glass fibers, (ii) polyolefine fibers, (iii) fibers selected from the group consisting of polyamide fibers, polyester fibers, and mixtures thereof, and (iv) a cross-linked latex binder, (b) consolidating the fibers and binder into a loosely packed mat, (c) curing the consolidated mat at a temperature in the range of about 250-400 F., and (d) molding the cured mat into a desired shape at ambient temperature.

Abstract: An automotive headliner comprised of a laminate of double corrugated paperboard. Perforations in all the sheets of the laminate except the back paperboard sheet improve the acoustical performance of the liner. A vapor barrier on the back sheet prevents entry of moisture into the laminate from the roof, and a layer of sound dampening material on the front face of the laminate improves the sound absorption of the laminate. The front corrugation is larger than the back corrugation. When molding the laminate it is first moisturized, then heat molded. Heat is applied until the laminate has regained its rigidity.
