Abstract
A benzophenone compound, and an ink composition that includes the benzophenone compound can absorb UV light, and thus improve lightfastness of images produced with the ink composition containing the compound. Due to the function of the benzophenone compound as a lightfast dispersant, the dispersibility and the lightfastness of an ink composition are improved with the benzophenone compound, without requiring an additional lightfastness enhancer.
