20100315715MULTILAYER FILM AND MANUFACTURING METHOD THEREOF - According to a manufacturing method of a multilayer film according to one aspect of the present invention, at the step of applying a coating liquid prepared by dissolving a plurality of monomers or polymers in at least one solvent onto a substrate and subsequently drying the coating liquid, the solvent is allowed to penetrate into the substrate at a specified speed. This causes concentration distribution of the solvent within the coated layer in the thickness direction thereof, and thus a multilayer film separated into an upper layer and a lower layer can be formed by one coating. Accordingly, a multilayer film having a different function in each layer can be formed by one coating.12-16-2010

20130182329Plastic Substrate having a Porous Layer and Method for Producing the Porous Layer - A plastic substrate has a porous layer on a surface. The porous layer is formed at least partially from a material of the plastic substrate and has pores. The proportion by volume of pores is greater in a first region of the porous layer than in a second region of the porous layer. The second region follows the first region, as seen proceeding from the plastic substrate. The porous layer can be produced by a plasma process that simultaneously effects structuring of the plastic substrate by ion bombardment and coating of the plastic substrate.07-18-2013
20120062995OPTICAL ELEMENT WITH ANTIREFLECTION FUNCTION AND OPTICAL APPARATUS INCLUDING THE SAME - An optical element having antireflection function includes a substrate including a first relief structure on a surface, the first relief structure including at least a convex shape and a concave shape being arrayed with a pitch of at most a half of a wavelength λ, and a thin film layer including a thin film of at least one layer on the first relief structure, wherein the thin film layer has a refractive index lower than the refractive index of the substrate, and when the thin film layer includes at least two thin films more, the thin film layer are arranged in order of decreasing the refractive index from a side of the substrate toward a side of air, and the following conditional expression is satisfied:03-15-2012
