Abstract
A white ink composition for ink jet recording characterized in comprising at least a white pigment, a polymerizable compound, and a polymerization initiator and having a viscosity of 10 to 500 Pa·s at 30° C. A method for ink jet recording comprising the steps of: heating an ink in an ink-jet head to be not less than 40° C. and jetting the ink onto an ink-jet recording medium.
Claims21
An ink for ink jet recording comprising at least a pigment, a polymerizable compound, and a polymerization initiator, wherein the ink has a viscosity of 10 to 500 Pa·s at 30° C. and a viscosity of 7 to 30 mPa·s when heated to at least 40° C.
An image forming method comprising the steps of:
- heating an ink in an ink-jet head so as to be not less than 40° C., and jetting the ink through an ink-jet head nozzle, wherein the ink has a viscosity of 10 to 500 mPa·s at 30° C., and has a viscosity of 7 to 30 mPa·s after heating to be not less than 40° C.
A method for producing a material by ink jet apparatus comprising the step of:
- jetting an ink onto an ink-jet recording medium, wherein the ink comprises a viscosity of 10 to 500 Pa·s at 30° C., and a viscosity of 7 to 30 mPa·s at a temperature which is same or vicinity of a temperature of an ink jet head nozzle when jetting.
