20130277881 | METHOD FOR MANUFACTURING LIGHT TRANSMISSIVE FILM, ACTIVE ENERGY RAY-CURABLE COMPOSITION, AND LIGHT TRANSMISSIVE FILM - A method for manufacturing a light transmissive film having a cured resin layer with a fine concavo-convex structure on a surface of a base material film is provided. The method includes sandwiching an active energy ray-curable composition including a mold dissolving component between a mold having an inversion structure of the fine concavo-convex structure and the base material film, obtaining a light transmissive film in which a cured resin layer having the inversion structure of the mold transferred is formed on one surface of the base material film, and separating the obtained light transmissive film and the mold. Thus, it is possible to productively manufacture a light transmissive film, and to prevent the deposition of an attachment on the mold surface and the contamination of the mold surface. Moreover, a light transmissive film can be manufactured having excellent performances, such as antireflection properties. | 10-24-2013 |

20150144185 | FILM, METHOD FOR PRODUCING SAME, PLATE-LIKE PRODUCT, IMAGE DISPLAY DEVICE, AND SOLAR CELL - A film which is provided with a concave-convex microstructure body that has a concave-convex microstructure formed of a cured product of an active energy ray curable resin composition on a surface and an ultraviolet ray blocking layer that is adjacent to a surface of the concave-convex microstructure body, the surface being on the reverse side of the concave-convex microstructure-side surface, a method for producing the film, and a plate-like product, an image display device and a solar cell that are provided with the film. | 05-28-2015 |
20150290844 | METHOD OF MANUFACTURING MOLD, AND MOLDED ARTICLE HAVING FINE RELIEF STRUCTURE ON SURFACE AND METHOD OF MANUFACTURING THE SAME - The present invention relates to a method of manufacturing a mold having an oxide film with a plurality of pores formed on a surface of an aluminum substrate, the method including (a) a process of applying a voltage to a machined aluminum substrate and anodizing a surface of the aluminum substrate to form an oxide film; and (b) a process of removing at least a part of the oxide film formed in the process (a), wherein a voltage (V | 10-15-2015 |
20150299888 | METHOD FOR PRODUCING ANODIC POROUS ALUMINA, METHOD FOR PRODUCING MOLDED ARTICLE HAVING MICROSCOPIC PATTERN ON SURFACE, AND MOLDED ARTICLE HAVING MICROSCOPIC PATTERN ON SURFACE - This method for producing anodic porous alumina such that an oxide coating film having a plurality of minute pores is formed at the surface of an aluminum substrate is characterized by containing: a step (a) for immersing the aluminum substrate in an electrolytic liquid resulting from mixing a plurality of acids; a step (b) for imposing a voltage on the aluminum substrate immersed in the electrolytic liquid; a step (c) for holding the aluminum substrate in the state of being immersed in the electrolytic liquid essentially without imposing a voltage on the aluminum substrate; and a step (d) for alternately repeating step (b) and step (c). By means of the present invention, it is possible using a simple device and with few steps to provide a method that easily produces anodic porous alumina such that an oxide coating film having a plurality of minute pores is formed at the surface of an aluminum substrate. | 10-22-2015 |
