An ink composition for inkjet recording including a compound represented by where R1 and R2 are each independently, hydrogen, a C1-C20 substituted or unsubstituted alkyl, a C2-C20 substituted or unsubstituted alkenyl, a C2-C20 substituted or unsubstituted alkynyl, a C6-C20 substituted or unsubstituted aryl, a C7-C20 substituted or unsubstituted arylalkyl, a C2-C20 substituted or unsubstituted cyclic alkyl, or a hetero atom-containing cyclic alkyl and M is hydrogen or Na, K, Li, or an ammonium ion. The ink composition may further include a coloring agent and water, so that the ink composition prevents formation of depositions therein over time to obtain high storage stability and good ejection properties.
