  • Patent number: 10253120
    Abstract: The present invention provides as steam barrier resin, a steam barrier coating agent, a steam barrier film, and a steam barrier laminate that exhibit an improved steam barrier property. The steam barrier resin is obtained by reacting a carboxylic acid group and/or an acid anhydride group of a copolymer (C) with an organometallic complex (D). The copolymer (C) is obtained by polymerizing an unsaturated hydrocarbon monomer (A) and an unsaturated carboxylic acid and/or an unsaturated dicarboxylic anhydride (B). Further, the steam barrier resin includes metal bridging between the copolymers (C). The steam barrier coating agent contains the steam barrier resin and a solvent (B). The steam barrier film of the present invention is a film containing the steam barrier. The steam barrier laminate is obtained by laminating the steam barrier film of the present invention on at least one surface of a substrate film.

  • Publication number: 20130331474
    Abstract: Provided is a resin composition for light scattering layer for use in forming a light scattering layer of an organic EL device, including: a binder composition including at least one type of resin (A); and light scattering particles (B). In a resin composition for light scattering layer of the invention, the light scattering particles (B) have an average particle diameter of 200 nm to 500 nm in the resin composition and have a content of 20 vol % or less of particles with a particle diameter of 600 nm or more with respect to a total amount of the light scattering particles (B); and a refractive index difference between the binder composition and the light scattering particles (B) is 0.1 or more.

  • Publication number: 20080054957
    Abstract: A skew correction apparatus is composed of a variable delay line 200 for generating a delayed clock signal DCLK by delaying a clock signal CLK by a variable delay amount DT, a phase comparator 10 for comparing a phase of the delayed clock signal DCLK with transition of rising of a data signal DAT, a voltage holding means 6 for holding a voltage Vcntl for controlling the delay amount DT of the variable delay line 200, a charging/discharging means 30 for charging or discharging the voltage holding means 6, depending on a comparison result of the phase comparator 10, a charging means 40 for setting the voltage Vcntl of the voltage holding means 6 during initial setting, and a control circuit 500 for controlling the charging means 40.
