  • Patent number: 8563085
    Abstract: In a method of forming a layer, a precursor composition including a metal and a ligand chelating to the metal is stabilized by contacting the precursor composition with an electron donating compound to provide a stabilized precursor composition onto a substrate. A reactant is introduced onto the substrate to bind to the metal in the stabilized precursor composition. The stabilized precursor composition is provided onto the substrate by introducing the precursor composition onto the substrate after the electron donating compound is introduced onto the substrate. The electron donating compound is continuously introduced onto the substrate during and after the precursor composition is introduced.

  • Patent number: 7718803
    Abstract: A self-dispersible bipyridine-based metal complex includes a bipyridine-based ligand and a metal, and an ink composition including the metal complex. The bipyridine-based metal complex may be self-dispersed without requiring a dispersing agent and may be used as a colorant per se. Furthermore, the metal complex, when binding with a common colorant, may produce various colors and exhibit enhanced durability including light resistance. In addition, the metal complex includes a hydrophilic group-containing ligand coordinating with the metal, in addition to the bipyridine-based ligand, and thus, has a bulky structure. Therefore, dispersion stability is enhanced by a self-dispersion system based on a steric hindrance due to the bulky structure of the metal complex and an electrostatic repulsive force between the charged metal and the hydrophilic group-containing ligand, thus enhancing a long-term storage stability.
