ABSTRACT:
The present invention relates to a photoelectrographic element having a conductive layer in electrical contact with an acid photogenerating layer which is free of photopolymerizable materials and contains an electrically insulating binder and an onium acid photogenerator. A dye or pigment which undergoes a color density or hue shift upon exposure with radiation is included in the photoelectrographic element. A method for forming images with this element is also disclosed.
