Patent number: 10030113Abstract: The invention provides a gas barrier film with low deterioration in the gas barrier property before and after high-temperature hot water treatment. The gas barrier film has a gas barrier coating film, formed as a composite film comprising a network structure having a mesh structure with Si—O—Si bonds as the basic lattice and a water-soluble polymer crystallized as microcrystals, incorporated into the mesh of the network structure, wherein a barrier coating agent, obtained by mixing a condensate solution of an alkoxysilane hydrolysate prepared as a mixed solution in which the proportion of bonded states of the silicon atoms of the condensate with Q1 and Q2 structures is at least 60% of the total silicon atoms, with a crystalline water-soluble polymer, is coated on a base material film, either after forming or without forming an aluminum oxide vapor deposition film, to form a coating layer.Type: GrantFiled: March 27, 2015Date of Patent: July 24, 2018Assignee: Dai Nippon Printing Co., Ltd.Inventors: Azusa Suzuki, Hiroyuki Iwahashi, Takeshi Nishizono, Shigeki Matsui, Kazutoshi Haraguchi

Patent number: 8283577Abstract: Intended is to provide an electromagnetic shielding material having a conductive layer pattern by transferring a conductive composite to a transparent base material, and an electromagnetic shielding material having a metal layer formed on the transferred conductive layer. The electromagnetic shielding material is free from the troubles such as the breaking of wire, the non-conforming shape or the low contact, which is based on the non-conforming transfer of the conductive composite. The electromagnetic shielding material comprises a transparent base material, a primer layer formed over the transparent base material, and a conductive layer formed in a predetermined pattern on the primer layer. In the primer layer, a portion having the conductive layer formed therein has a thickness larger than the thickness of a portion without the conductive layer.Type: GrantFiled: June 6, 2008Date of Patent: October 9, 2012Assignee: Dai Nippon Printing Co., Ltd.Inventors: Nobuo Naito, Hironori Kamiyama, Nozomi Kaga, Yuichi Miyazaki, Takeshi Nishizono, Hidetsugu Tazawa, Shinya Kiura
