Patent number: 5059272Abstract: A conductive high molecular composition which comprises a non-conductive polymer component incorporated with a metal salt, characterized in that the metal salt is a salt of a metal with an acid substance selected from an organic carboxylic acid, rosin and a rosin derivative. This composition has an insulating property in normal state but functions as an electroconductive material only in the event it is interposed between slightly spaced metals and heated. Thus, the composition can be used not only as an insulating binder but also for imparting conductivity only in the desired spots of electronic parts, keeping the other areas of the parts electrically insulated. The composition thus possessing a specific dual function is particularly useful in the field of electronic industry.Type: GrantFiled: April 27, 1989Date of Patent: October 22, 1991Assignee: Harima Chemicals, Inc.Inventors: Masanao Kono, Yoshihiro Hasegawa, Yasutaka Nishi, Yasuyoshi Sanada, Tatsuji Mizuta, Ryo Inoue, Shinsuke Ohara

Patent number: 5021269Abstract: A method for forming a metal film on the surface of a substrate metal, which comprises soaking a substrate metal or a non-metal support carrying the substrate metal thereon in a solution of a metal salt in a high boiling point solvent under heating conditions, characterized in that the metal salt is a salt of the metal to be formed on the surface of the substrate metal with an acidic substance selected from an organic carboxylic acid, a rosin and a rosin derivative. The metal is precipitated from the solution exclusively on the surface of the substrate metal without forming any solid metal particle in the solution or on the substrate metal. Thus, the method is applicable to the formation of a soldering alloy as a film on the surface of a substrate metal without leaving thereon any free metal particle which may cause short circuits in electronic circuits.Type: GrantFiled: March 13, 1989Date of Patent: June 4, 1991Assignee: Harima Chemicals, Inc.Inventors: Masanao Kono, Yoshihiro Hasegawa, Yasutaka Nishi, Hisao Irie, Tatsuji Mizuta, Shinsuke Ohara
