  • Patent number: 8410206
    Abstract: The invention concerns the use of cerium dioxide, especially in the form of discrete cerium dioxide particles with particle sizes in the range from 0.005 to 150 ?m, as inorganic radical trap to stabilize organic polymers, especially in the form of polymer-based formulations, varnishes, paints, coating compounds, or the like, against their photochemically, thermally, physically and/or chemically induced degradation by free radicals, especially against the effect of UV, advantageously in an optional combination with at least one UV-absorber and/or at least one additional radical trap. The radical-induced degradation of the organic polymers is effectively prevented by the use of cerium dioxide without the cerium dioxide itself becoming degraded. If a combination of cerium dioxide with an additional UV-absorber or radical trap is used, its effectiveness is extended through the presence of the cerium dioxide.

  • Patent number: 7579074
    Abstract: The present invention relates to an aqueous colloidal gold solution, comprising (a) nano-particular gold particles, (b) a compound having a polar tertiary amino group conjugated via a hydrophobic aromatic residue with a weaker alkaline group, and (c) a stabilizer comprising a mercapto group (—SH) and an acidic group, in particular a sulfonic acid group (—SO3?). This gold solution uses an ecologically compatible medium and is suited in an especial manner or writing and for printing, also for inkjet printers, since it has a long-term storage life and generates an attractive metal-like gold sheen.
