where, R 3 and R 4 each, independently represent monovalent groups comprising groups represented by —OX 1 , where X 1 represents a monovalent hydrocarbon group having 1 to 10 carbon atoms, a monovalent group comprising a group represented by —COOX 2 , where X 2 represents a monovalent hydrocarbon group having 1 to 10 carbon atoms, a monovalent group comprising a group represented by —OCOX 3 , where X 3 represents a monovalent hydrocarbon group having 1 to 10 carbon atoms, a monovalent group comprising a group represented by —NX 4 X 5 , where X 4 and X 5 each, independently represent monovalent hydrocarbon groups having 1 to 10 carbon atoms, a monovalent group comprising a group represented by —CONX 6 X 7 , where X 6 and X 7 each, independently represent monovalent hydrocarbon groups having 1 to 10 carbon atoms, or a monovalent group comprising a hydroxyl group,

where a ring A represents a saturated five-membered ring or a saturated six-membered ring, both comprising a nitrogen atom, R 5 represents a monovalent group comprising a group represented by —OX 1 , where X 1 represents a monovalent hydrocarbon group having 1 to 10 carbon atoms, a monovalent group comprising a group represented by —COOX 2 , where X 2 represents a monovalent hydrocarbon group having 1 to 3 carbon atoms other than a t-butyl group, a monovalent group comprising a group represented by —OCOX 3 , where X 3 represents a monovalent hydrocarbon group having 1 to 10 carbon atoms, a monovalent group comprising a group represented by —NX 4 X 5 , where X 4 and X 5 each, independently represent monovalent hydrocarbon groups having 1 to 10 carbon atoms, a monovalent group comprising a group represented by —CONX 6 X 7 , where X 6 and X 7 each, independently represent monovalent hydrocarbon groups having 1 to 10 carbon atoms, or a monovalent group comprising a hydroxyl group, and a is 1, 2, or 3, and

where a ring B represents a saturated five-membered ring or a saturated six-membered ring, both comprising two nitrogen atoms, R 6 represents a monovalent group comprising a group represented by —OX 1 , where X 1 represents a monovalent hydrocarbon group having 1 to 10 carbon atoms, a monovalent group comprising a group represented by —COOX 2 , where X 2 represents a monovalent hydrocarbon group having 1 to 10 carbon atoms, a monovalent group comprising a group represented by —OCOX 3 , where X 3 represents a monovalent hydrocarbon group having 1 to 10 carbon atoms, a monovalent group comprising a group represented by —NX 4 X 5 , where X 4 and X 5 each, independently represent monovalent hydrocarbon groups having 1 to 10 carbon atoms, a monovalent group comprising a group represented by —CONX 6 X 7 , where X 6 and X 7 each, independently represent monovalent hydrocarbon groups having 1 to 10 carbon atoms, a monovalent group comprising a hydroxyl group, or an alkyl group having 1 to 10 carbon atoms,
wherein, in each of Chemical Formula 2, 3, and 4, when R 3 , R 4 , and R 6 represents —OX 1 , —OX 1 is bound to the nitrogen atom through an alkylene group that has at least three carbon atoms, and
a viscosity of the ink ranges from 7 mPa·s to 30 mPa·s.

2. The ink according to claim 1 , wherein the ink comprises the compound represented by chemical formula 1, wherein R 1 represents a cycloalkyl group, an aryl group, or an aralkyl group.

3. The ink according to claim 1 , wherein R 3 and R 4 each independently represent 2-hydroxyethyl group.

4. The ink according to claim 1 , wherein the ink comprises the compound represented by chemical formula 3, which is represented by chemical formula 6

5. The ink according to claim 4 , wherein R 5 is a group represented by —COOX 2 , where X 2 represents a hydrocarbon group having 1 to 10 carbon atoms other than a t-butyl group.

6. An ink cartridge comprising:
