Abstract
A new structure comprising a layer of an imaging material, capable of undergoing an image forming change in response to energy, a layer of a barrier material and a layer of a catalyst material which, if necessary after activation, is capable of causing or promoting the image forming change in the imaging material. The barrier material is capable of controlling in accordance with a desired image pattern, the passage of the catalyst material through the barrier layer into contact with the imaging material in selected areas, while it prevents passage of the catalyst material in other selected areas. The permeability of the barrier layer for the catalyst material and, if necessary the activation of the catalyst material, may be controlled by the selective imagewise application of imaging energy to the structure, and the image forming change in the imaging material may be brought about by the application of development energy, such as heat, to the structure to produce a detectable image in the layer of the imaging material.
