Patent number: 7959832Abstract: The present invention is a transparent conductor containing electrically conductive particles, a binder, and an ultraviolet absorber. The transparent conductor of the present invention is so arranged that the ultraviolet absorber in the transparent conductor absorbs ultraviolet light even during irradiation of the transparent conductor with ultraviolet light, and is thus able to suppress influence of ultraviolet light on the electrically conductive particles.Type: GrantFiled: April 28, 2006Date of Patent: June 14, 2011Assignee: TDK CorporationInventors: Noriyuki Yasuda, Chieko Yamada

Patent number: 7678446Abstract: The transparent conductor of the present invention comprises a conductive layer containing a conductive particle, a binder, a polymerization initiator, and a radical scavenger. In the transparent conductor of the present invention, the conductive layer contains the radical scavenger in addition to the conductive particle. Therefore, even when the conductive particle is pumped upon irradiation with UV rays, so that a radical occurs in the conductive layer, the radical scavenger contained in the conductive layer captures the radical. This restrains the radical from acting on the remaining polymerization initiator and thereby causing a side reaction. As a result, adjacent conductive particles are restrained from fluctuating the distance therebetween.Type: GrantFiled: June 28, 2006Date of Patent: March 16, 2010Assignee: TDK CorporationInventors: Noriyuki Yasuda, Chieko Yamada

Patent number: 7452435Abstract: A functional film of the invention includes a microparticulate-containing layer containing functional microparticulates. The microparticulate-containing layer inhibits the occurrence of cracks even when drawn 10%. When the functional film includes a microparticulate-containing layer containing conductive microparticulates, the microparticulate-containing layer exhibits a surface resistivity after drawn 10% which is at most 10 times greater than the surface resistivity prior to drawing. The invention thus implements a functional film which is unsusceptible to reduction or loss of its function due to deformation.Type: GrantFiled: July 8, 2003Date of Patent: November 18, 2008Assignee: TDK CorporationInventors: Kiminori Tamai, Tadayoshi Iijima, Chieko Yamada, Shigeyo Miyamori
