Claims9
An ink-jet pigment ink, comprising:
- at least one low-molecular compound represented by the following formula (1-1) or formula (2-1):
- and
- a polymer having at least one polyethylene oxide block structure,
- wherein a viscosity of the ink jet pigment ink at 65° C. increases to 100 mPa·s or more in response to heating,
- wherein, in formula (1-1), R11, R12, R13 and R14 each independently represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms;
- R13 and R14 may be bonded to each other to form a ring;
- and X represents an oxygen atom or a sulfur atom, and
- wherein, in formula (1-2), R21 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms;
- Y represents an oxygen atom or a sulfur atom;
- and n represents an integer of 1 to 3.
