Abstract:
1. 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 printed substrate, the printed substrate being coated with a coating composition comprising at least one acrylic emulsion, at least one amino alcohol or at least one alkali base, and at least one surfactant, and having a viscosity of from about 50 cP to about 750 cP at about 25° C. before drying, 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.
