This invention relates to a carbonless multiple ply credit card form. The top ply of the form is a substantially translucent ply which is stacked on top of at least a second ply. When the two plies are contacted under sufficient pressure, a chemically produced positive visible image results on both the bottom surface of the substantially translucent ply and the top surface of the second ply. The image on the bottom of the translucent ply is readable when viewed through the ply.
