Abstract
The overcoat emulsion for protection a carbon spot or other image transfer medium against smudging is made from a polyethylene wax emulsion. In addition, a stilt such as wheat starch may be added to the emulsion to improve the pressure absorbing qualities of the overcoat. In addition, a surfactant may be added to the emulsion to improve the wettability characteristics of the emulsion when being applied to a substrate such as a paper ply of a mailer.
Claims11
A mailer form comprising
- a front ply having a front face for impacting of an imaging means thereon and a rear face;
- a back ply secured to said front ply to define a pocket therewith;
- at least one insert ply disposed in said pocket between said front ply and said back ply;
- an image transfer medium on said rear face of said front ply for transferring an image imposed on said front ply under an impact force of an imaging means onto said insert ply;
- and
- a polyethylene wax overcoat over at least a part of said transfer medium to reduce transfer of an image imposed on said front ply under a transversely applied force onto said insert ply while transferring an image imposed on said front ply under an impact force onto said insert ply.
