Patent number: 7153352Abstract: An ink for inkjet recording containing a vehicle, coloring agents dispersed therein, and a dispersing agent for the coloring agents as required, is provided. The vehicle contains at least a first solvent component and a second solvent component. The first solvent component has the lowest boiling point among the components in the ink, and has a higher viscosity than the ink. The second solvent component has a higher boiling point than the first one. The boiling point of the first solvent component is preferably 280 degree C. or below, and the content thereof is preferably 10 to 80% by weight based on the total weight of the ink. Even when the ink is printed on non-coated papers, the vehicle penetrates little in the thickness direction and bleeds little in the horizontal direction. Clogging in the nozzles can be prevented effectively using the ink even when it has been left in an open atmosphere for a long time.Type: GrantFiled: May 11, 2004Date of Patent: December 26, 2006Assignee: Riso Kagaku CorporationInventors: Hiroyuki Ogawa, Toshihiro Endo, Hajime Tsunoda, Teruaki Ohkawa, Osamu Matsumoto
