Abstract: Described herein is a polar non-aqueous dispersion comprising polar polymeric microparticles in a polar non-aqueous medium, the polar polymeric microparticles being insoluble in the medium and being produced by dispersion polymerization of vinyl monomers such as acrylate monomers in the medium in the presence of a polymeric acrylic stabilizer. Inks, coatings and overprint varnishes are formulated that employ the polar non-aqueous dispersion. Such inks, etc., exhibit superior chemical resistance properties, for example in one-part and two-part systems.

Abstract: A method for measuring the radiant exposure of energy curable inks or coatings on a printing press. The steps for measuring comprise: a) providing an ink or coating material comprising a fluorescent probe; b) transferring the ink or coating material onto a substrate using a printing process; c) exposing the ink or coating material to actinic radiation capable of initiating cure of the ink or coating material that also alters the luminescence of the probe; d) exposing the ink or coating to a first source of excitation light with wavelength and luminance capable of absorption by the fluorescent probe; and e) measuring the emitted light from the fluorescent probe by a first detector.

Abstract: Described herein are tamper-evident adhesive seals for sealing articles, containers, and other enclosure in which a covert tamper evidencing agent is included in an adhesive sealing material. The presence of the covert tamper evidencing agent reveals evidence of tampering when exposed to UV light.

Abstract: Monatomic metal anions are generated in the gas phase by collision-induced dissociation of the anions [26] of a dicarboxylic acid salt of the metal. This method is applicable to a number of metals, including sodium, potassium, cesium, and silver. The metal anions produced in this way can subsequently be stored in an ion trap [88] or transmitted as a focused beam [52]. The metal anions of this invention undergo collisional cooling and have low kinetic energy, which distinguishes them from ions produced by other high energy processes (with kinetic energy in excess of 1 keV). Metal anions so produced can be used to pattern nanoscale features on surfaces [56], used as electron transfer agents or reducing agents in ion-molecule reactions, or used for surface [122] modification of biomaterials [124].
