  • Fluorine-free trisiloxane surfactant compositions for use in coatings and printing ink compositions
    Publication number: 20080090963
    Abstract: The present invention relates to coating and printing ink compositions possessing silicone surfactants compositions comprising fluorine-free organomodified trisiloxanes which are resistant to hydrolysis between a pH of about 3 to a pH of about 12. The coatings and printing ink composition of the present invention exhibit enhanced wetting, flow and leveling properties.

  • Organic dye compositions and use thereof in photovoltaic cells
    Publication number: 20070028961
    Abstract: The present invention provides in one aspect a composition having at least one croconine derivative. This composition may be disposed on a semiconductor layer which is further disposed on an electrically conductive surface to provide a dye-sensitized electrode. The dye-sensitized electrode can be assembled together with a counter electrode and a redox electrolyte to provide a photovoltaic cell. The photovoltaic cell may be used as a single cell or in tandem with other cells.
