Abstract

The production of an image in a dry process by forming a vesicle image upon the decomposition of a peroxide compound at image nuclei of silver by providing a layer containing a silver salt which forms upon exposure to light, in imagewise distribution, image nuclei. The silver salt has a grain size of less than 0.3 .mu.m and is present in the layer in an amount of from 1 - 500 mg/m.sup.2.
