ABSTRACT:
Imaging means, such as a tetrazolium salt, capable of reduction to form a visible image is present in a radiation-sensitive layer in combination with a photoreductant incorporating one or more labile hydrogen atoms and capable of producing a reducing agent precursor in radiation-struck areas of the layer. An image is produced in the layer by processing the layer after imagewise exposure to actinic radiation.
