ABSTRACT:
A lightfast additive and an ink composition including the same include a benzophenone moiety for lightfastness and a moiety for wettability and the ability to stabilize a colorant, wherein the two moieties are covalently bonded. The lightfast additive may exhibit effective ultraviolet (UV) light absorption capacity, effective wettability, and an ability to stabilize a colorant. The ink composition utilizing the light fast additive thus has an improved lightfastness and long-term storage stability.
