Abstract
A 2-methoxyphenol derivative and an ink composition containing the 2-methoxyphenol derivative, an aqueous medium, and a colorant enhance light resistance by absorbing ultraviolet (UV) light, provide wettability and stabilize a colorant. The ink composition prepared using the 2-methoxyphenol derivative also has improved light resistance, wettability and stabilizes a colorant and does not require an additional light-resistant agent.
