Abstract
Abstract The front ply of the mailer is provided with a cutout window and a transparent patch over the window. The patch is provided with a CB coating while the underlying area of the insert ply is provided with a CF coating for chemically reacting with the first coating in response to an impact force from a stylus on the patch. Imaged information on the insert ply can be viewed through the transparent patch while being protected by the patch.
