Abstract
A 2-methoxyphenol derivative may be used as an ultraviolet (UV) light absorbing dispersant and, an ink composition may include the 2-methoxyphenol derivative as a light-resistant dispersant. The 2-methoxyphenol derivative absorbs UV light and thus provides light resistance to outputs. The 2-methooxyphenol derivative also improves dispersibility. When the 2-methoxyphenol derivative is used to prepare an ink composition, the ink composition has improved dispersibility and light resistance, and there is no need to add a light-resistant additive.
