|20130216945||PIGMENT DISPERSION LIQUID, A METHOD FOR PRODUCING THE PIGMENT DISPERSION LIQUID, A PHOTOSENSITIVE COLOR RESIN COMPOSITION COMPRISING THE PIGMENT DISPERSION LIQUID, AN INK-JET INK COMPRISING THE PIGMENT DISPERSION LIQUID, A TONER FOR ELECTROPHOTOGRAPHIC PRINTING COMPRISING THE PIGMENT DISPERSION LIQUID, AND COLOR FILTER - An object of the present invention is to provide a pigment dispersion liquid which has excellent pigment dispersion stability and high productivity even in the case of using a fine pigment and having high pigment concentration; a method for producing the pigment dispersion liquid; a color resin composition which has excellent pigment dispersion stability, causes no clogging problem, has excellent adhesion, and is able to form color layers with high pigment concentration, with accuracy; and a color filter comprising the resin composition.||08-22-2013|
|20120077896||ACTIVE ENERGY RAY CURABLE-TYPE INKJET RECORDING INK COMPOSITION - The object to be achieved by the present invention is to provide an active energy ray curable-type inkjet recording ink composition that is used for recording on a glass surface and is excellent in adhesiveness to the glass surface and water resistance and alcohol resistance. The active energy ray curable-type inkjet recording ink composition of the present invention at least contains: (b) photopolymerization initiator; 40 to 75 percent by mass of (d) cyclic monofunctional (meth)acrylate; 5 to 20 percent by mass of (e) hydroxyl group-containing (meth)acrylate; and 3 to 10 percent by mass of (c) epoxy group-containing silane coupling agent. The active energy ray curable-type inkjet recording ink composition is used for recording on a glass surface.||03-29-2012|
|20110157704||ANTIREFLECTIVE FILM AND PRODUCTION METHOD THEREOF - It is aimed at finding out a surface pattern and physical properties required for an antireflective film having an excellent antireflective property for light, a light transmissivity, and the like, and at providing an antireflective film having such a specific surface pattern and physical properties, and a production method of the antireflective film; and provided for this object, is an antireflective film, obtained by: processing a surface of an aluminum material, by mechanical polishing, chemical polishing and/or electrolytic polishing; subsequently producing a pattern of mold having taper-shaped pores on the surface of the aluminum material, by combining a formation of an anodic oxide coating based on anodic oxidation of the surface of the aluminum material, with etching of the anodic oxide coating; and transferring the pattern of mold onto an antireflective film-forming material; wherein the antireflective film has, on a surface thereof, convexities having an average height between 100 nm inclusive and 1,000 nm inclusive, or concavities having an average depth between 100 nm inclusive and 1,000 nm inclusive, and the convexities or concavities are present at an average period between 50 nm inclusive and 400 nm inclusive, at least in a certain single direction; and wherein the antireflective film has a haze of 15% or less.||06-30-2011|
