Abstract:
The present invention provides a process for preparing a printing plate, comprising the steps of: providing an N-type photoconductor layer having an optical memory property on the surface of a substrate having an electrical conductivity at least in its surface to form an N-type photoconductor substrate; subjecting the N-type photoconductor layer to a desired pattern-wise exposure by batch exposure and/or photo-drawing exposure to render exposed areas electrically conductive; immersing the N-type photoconductor substrate in an electrodeposition bath to electrodeposit an ionic organic polymer contained in the electrodeposition bath to form an electrodeposit layer; and washing and drying the electrodeposited substrate to prepare a printing plate.Further, the present invention provides a process for preparing a printing plate, comprising the steps of: subjecting an N-type photoconductor layer provided on an N-type photoconductor substrate to a desired pattern exposure by batch exposure and/or photo-drawing exposure to render exposed areas electrically conductive; electrodepositing an ink-receptive component on the exposed areas; and transferring the ink-receptive component onto a substrate for a printing plate to prepare a printing plate having an ink-receptive area.Furthermore, the present invention provides a process for preparing a printing plate, comprising the steps of: exposing the whole surface or a necessary region of an N-type photoconductor layer provided on an N-type photoconductor substrate, thereby rendering exposed areas electrically conductive; heating the exposed areas by hot pattern drawing to erase the conductivity of the heated areas; and electrodepositing an electrodeposition material on the remaining conductive areas to form an electrodeposit layer.
Abstract:
An electric current conductive composition comprising benzotriazole or a derivative thereof and a substantially electrically insulating binder, which is an essential component of an image recording element. The image recording element comprises a support having thereon a layer of the electric current conductive composition further containing a reducible metal compound, preferably an organic silver salt, a reducing agent, and having on different sides thereof an electrically conductive layer, with at least one of the electrically conductive layers being capable of transmitting actinic radiation. Image recording is accomplished by passing in the image recording element an image-wise pattern of an electric current sufficient to produce therein a storable latent image, followed by heating at least the electric current conductive composition layer to produce a visible image at the areas where the electric current passed through the electric current conductive composition.
