摘要

A sampler for delivery of microencapsulated liquid material has a protective treatment disposed on the substrate sheet overlying ink on the sheet, with microcapsules comprising microencapsulated organic liquid capsule fill disposed on at least a portion of the protective treatment and overlying at least a portion of the ink. The protective treatment is water-stable and organic liquid capsule fill-stable, and is a polymeric solution or emulsion that may be coated on the substrate sheet in a standard coating process in line with the printing of ink on the substrate sheet, and will cure in line to provide the desired protective properties.
