  • Patent number: 10401535
    Abstract: A graded index antireflection layer may be formed on a transparent crystalline member such as a sapphire member. The graded index layer may include aluminum oxide and silicon oxide. The graded index layer may extend from a first surface at the transparent member to a second surface. The fraction of aluminum oxide in the graded index layer may be at a maximum at the first surface so that the index of refraction of the graded index layer at the first surface matches the index of refraction of the transparent member and may be at a minimum at the second surface so the index of refraction of the graded index layer is minimized at the second surface. The graded index layer may be annealed to form aluminum oxide nanocrystals in the graded index layer and to form a polycrystalline aluminum oxide adhesion layer at the first surface.

    Abstract: Disclosed are non-spherical resin particles that allow for improvement of light diffusion, light reflection, and other related properties, and a manufacturing method thereof. The particles comprise first and second, different resin components (1) and (2), with the second resin component (2) residing locally near the surface of the non-spherical resin particles. The method of manufacturing non-spherical resin particles involves either allowing particles of a resin to absorb a vinyl-based polymerizable monomer contained in an aqueous emulsion followed by polymerization of the absorbed monomer or dissolving a resin in a vinyl-based polymerizable monomer followed by polymerization of the obtained solution in an aqueous medium. In the method, the resin has a site derived from a (meth)acrylic acid ester having a C2-C10 halogenated alkyl group or alicyclic hydrocarbon group and has a weight-average molecular weight of from 150,000 to 1,000,000.
