Abstract
Disclosed herein is a xerographic print comprising a substrate with a toner-based image printed thereon, the printed substrate including low surface tension portions having a surface tension of no more than about 22 mN/m at 25 Deg. C. resulting in a surface tension gradient field on the substrate, the printed substrate being coated with a coating comprising at least one surfactant and a film-forming polymer, the coating having a liquid phase surface tension at 25 Deg. C. not exceeding the surface tension of the low surface tension portions of the printed substrate by more than about 2 mN/m, the coating having substantially no pinholes and being sufficiently resistant to permeation by the fuser oil to exhibit an effective absence of haze 24 hours after application. A system and a method of applying a substantially pinhole-free and haze-free coating substantially immediately after print fusing also are disclosed.
