  • Film-forming composition
    Patent number: 9618654
    Abstract: This film-forming composition includes, for example, a polymer, crosslinking agent and light-diffusing agent that contain a triazine ring-containing repeating unit structure such as that represented formula (17), and is able to provide cured films with good light diffusing properties. Furthermore, this film-forming composition, which includes the same polymer, crosslinking agent and fine inorganic particles having a cross-linkable functional group, is able to provide cured films with good high temperature and high humidity resistance.
    Type: Grant

  • CARBON MATERIAL DISPERSED FILM FORMATION COMPOSITION
    Publication number: 20160160079
    Abstract: A carbon material dispersed film formation composition including: a polymer that includes a triazine ring-containing repeating unit structure, such as that represented by formula (17) for example; a cross-linking agent; and a carbon material. The carbon material is well dispersed in the composition, and therefore by using this composition, a cured film in which the carbon material is well dispersed can be produced.

  • Surfactant for stabilizing water/supercritical carbon dioxide microemulsion
    Patent number: 9101894
    Abstract: There is provided a highly branched hydrocarbon based surfactant for stabilizing a water/supercritical carbon dioxide microemulsion. A surfactant comprising: a sulfate compound of Formula (1): R1—OSO3M??(1) (where R1 is a C6-30 hydrocarbon group having a branched chain; and M is a hydrogen atom, an alkali metal, ammonium, a basic amino acid residue, an alkanolamine residue having a C2-3 hydroxyalkyl group, or an aliphatic alkanolammonium) for stabilizing a water/supercritical carbon dioxide microemulsion.
