Abstract
The image transfer medium, such as a carbon spot or microcapsule type of medium is provided with a protective overcoat which precludes smudging of an insert ply within the mailer form due to the rubbing of the face of the mailer form. The overcoat serves to preclude or greatly reduce an image transfer under a transversely applied rubbing force while allowing transfer of an image under impact force.

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
- an 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.
