Fibrous structures including an active agent and having a graphic printed thereon
The present disclosure relates to fibrous structures including active agents and having a graphic printed thereon. In some embodiments, a nonwoven web may include a fibrous structure comprising filaments. In turn, the filaments may include filament forming material, and an active agent releasable from the filaments when exposed to conditions of intended use. In addition, a graphic may be printed directly onto the fibrous structure.
