A new type imaging system based upon the peel apart procedure has been described. In this system metal images are formed by using the sensor which consists of a photosensitive layer and a thin metal layer deposited on a substrate. In this paper, the peel force between the photosensitive layer and the metal layer was measured by changing the process factors such as, the concentration of the photosensitive materials, the thickness of the photosensitive layer and the heating period after exposure. The experimental results indicated that light illumination caused a change in the adhesive force between the photosensitive layer and the metal layer. Heat-treatment resulted in “ Fogging ” under certain conditions because the adhesive force between the metal layer and the substrate was decreased. An intermediate layer of PVC between the photosensitive layer and the metal layer accounted for decreasing fog and increasing the shelf life.
