Abstract: A barrier pigment is added to a fluorescent ribbon to prevent light from being absorbed into the media upon which the pigment is applied during printing. The barrier pigment is added to the fluorescent layer or is applied over the fluorescent layer as an additional layer.

Abstract: A fluorescent resin useful in water based ink jet printing based upon both molecular weight and degree of crosslinking of the resin during the manufacture is made utilizing trimellitic anhydrides, propylene glycol, neopentyl glycol, or both, and zinc acetate.

Abstract: Processes are taught for the substitution of at least partially amorphous carbon with mono- and bi-dentate phosphine ligands. The ligand-substituted carbon, on combination with complexed Group VI or VIII metals, such as Wilkinson's rhodium catalyst, provide stable heterogeneous catalysts useful in reactions of the Oxo type such as hydroformylation, carbonylation and in hydrogenation.

Abstract: The solvent barrier property of pigmented, solid polymeric articles is improved by pretreating the pigment particles prior to incorporation into the solid polymeric material so as to remove trapped gas from the surface and interstices of the pigment particles. Specific techniques for accomplishing this result include heating the pigment particles to a temperature above about 50.degree. C., but below the calcination temperature, scrubbing the pigment particles with an inert gas and subjecting the pigment particles to a vacuum.

Abstract: An ink composition for utilization in ink jet printing comprising an aqueous solution of a fluorescent pigment, a dye solubilizer, and butyl carbitol. The composition is nonflammable and has a relatively stable viscosity.

Abstract: The present invention relates to surface modification of synthetic resin fiber form materials, notably polyolefin and polyacrylonitrile fiber form materials whose surface has been modified by treatment with elemental fluorine, and to the fluorination process.

Abstract: The present invention relates to surface modification of synthetic resin fiberform materials, notably polyamide and polyester fiberform materials whose surface has been modified by treatment with elemental fluorine, and to the fluorination process.

Abstract: This invention relates to a process for improving the water wicking and moisture transport properties of synthetic resins, e.g., fiber form polyamides, polyesters, polyolefins, and polyacrylonitriles, which comprises sulfofluorinating said resins in a self-activating gaseous reaction medium containing from about 0.1-20% by volume elemental fluorine, 0.1-50% by volume of sulfur dioxide, 0-21% by volume oxygen, and the balance inert for providing from 1 .times. 10.sup.-.sup.9 to 1 .times. 10.sup.-.sup.3 milligrams fluorine and sulfur per square centimeter of resin surface.
