Patent number: 7776436Abstract: A hardcoat for a plastic substrate film is provided which has good suitability for printing and satisfactory hardness, can prevent influence of the deformation of a plastic substrate film from extending to the hardcoat, and is resistant to cracking and peeling. The hardcoat is produced from a coating component containing one or more organic components having a polymerizable functional group and an inorganic filler, at least one of the organic components being free from a hydrogen bond-forming group. In the hard coat, the content of the inorganic filler in the surface of the hardcoat is higher than that in the interior of the hardcoat. The hardcoat can be applied to antireflection films and hologram labels.Type: GrantFiled: August 12, 2003Date of Patent: August 17, 2010Assignee: Dai Nippon Printing Co., Ltd.Inventors: Toshio Yoshihara, Yurie Ota, Nobuko Takahashi, Noboru Kunimine, Satoshi Shioda, Mikiko Hojo

Patent number: 6893313Abstract: A method for forming a protective layer for a dielectric material in an alternating current type plasma display is provided. In this connection, a coating sol solution is provided which can form a protective layer on a large area substrate without the need to introduce any expensive equipment, the protective layer thus formed being excellent in properties such as strength, adhesion, transparency, and protective properties and capable of being formed by a sol-gel process without use of the conventional vacuum process. The sol solution comprises a dispersion of a precursor to magnesium oxide in a specific form. A method for film formation, using this solution is also provided.Type: GrantFiled: June 10, 2002Date of Patent: May 17, 2005Assignee: Dai Nippon Printing Co., Ltd.Inventors: Satoshi Mitamura, Toshio Yoshihara, Nobuko Takahashi

Patent number: 6682594Abstract: A process for making a functional film by adding a magnesium alkoxide and a diethanolamine, which can dissolve or disperse the magnesium alkoxide, in an organic solvent followed by allowing hydrolysis of the magnesium alkoxide to proceed in a rate-controlling manner wherein the magnesium alkoxide is dissolved or dispersed in the organic solvent. Water is added in no more than a stoichiometric amount to the solution or dispersion partially to hydrolyze the magnesium alkoxide. The partial hydrolyzate solution is matured to grow magnesium oxide and/or magnesium hydroxide particles, resulting in a stable sol solution.Type: GrantFiled: June 5, 2002Date of Patent: January 27, 2004Assignee: Dai Nippon Printing Co., Ltd.Inventors: Toshio Yoshihara, Nobuko Takahashi, Satoshi Mitamura

Patent number: 5976236Abstract: There are provided a coating composition that can satisfactorily form a film even at a low temperature by chemical means in a simple and stable manner, has excellent film strength, adhesion, protective effect and other properties in the form of a functional film and can form a functional film at a low cost, a process for producing the coating composition, a functional film, and a process for producing the functional films.A hydrolyzable reaction site is partially hydrolyzed to prepare a sol of a partial hydrolyzate which is then coated on a substrate. The coating is then baked to prepare a corresponding metal oxide film, thereby forming a thin protective layer. Since no hydrolyzate is precipitated in the sol of the partial hydrolyzate, excellent film strength, adhesion, protective effect and other properties are offered.Type: GrantFiled: March 26, 1996Date of Patent: November 2, 1999Assignee: Dai Nippon Printing Co., Ltd.Inventors: Toshio Yoshihara, Nobuko Takahashi, Satoshi Mitamura
