Patent number: 8278371Abstract: A nonaqueous inkjet ink composition that at printing by an inkjet printer, is free from clogging of a nozzle of printer head part and that excels in ink delivery stability leading to prints of excellent printing quality. The nonaqueous inkjet ink composition is one containing a pigment, a resin, a pigment dispersant, an organic solvent and an aminated alcohol, characterized in that the content of the aminated alcohol is in the range of 0.01 to 3 mass % based on the whole mass. The nonaqueous inkjet ink composition may be one characterized in that the water extract from the nonaqueous inkjet ink composition exhibits a pH value ranging from 6.0 to 10.0.Type: GrantFiled: January 31, 2008Date of Patent: October 2, 2012Assignee: Dai Nippon Toryo Co., Ltd.Inventors: Toshihiko Shiotani, Takehiro Kotera, Kazuki Moriyama, Emiko Osaka, Hiroki Hayashi, Tetsuo Sugawa
