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.
A structure comprising a layer comprising an imaging material which is capable of an image forming change upon the application of energy and wherein the image forming change can be promoted by a catalyst material, a barrier layer, comprising a barrier material, in contact on one side with said layer of imaging material, and in contact with said barrier layer on the opposite side thereof a layer comprising a catalyst material, which is capable of traversing the barrier layer and of promoting, in activated form, the image forming change in said layer of imaging material, wherein the layer of barrier material has the capacity of controlling transmission of the catalyst material from the layer of catalyst material to the layer of imaging material in response to energy.
A structure comprising a layer of a memory material, which is capable of undergoing a physical change in structure in response to energy, a barrier layer comprising a barrier material in contact on one side with said layer of memory material, and in contact with said barrier layer on the opposite side thereof a layer comprising a catalyst material, which is capable of traversing the barrier layer and of promoting, in activated form, the physical change in structure in said memory material, wherein the layer of barrier material has the capacity of controlling the transmission of the catalyst material from the layer of catalyst material to the layer of memory material in response to energy.
A structure comprising a layer of memory material, which is capable of undergoing a physical change in structure in response to the effect of energy, a layer of a barrier material in contact on one side with said layer of memory material, and a layer of an inactive catalyst material in contact with said layer of a barrier material on the opposite side thereof, wherein the layer of barrier material has the capacity of controlling the transmission of the catalyst material from the layer of catalyst material to the layer of memory material in response to energy, and wherein the inactive catalyst material is a material, which when activated, and in contact with said layer of memory material catalyzes the physical change in structure of the memory material, and wherein the barrier material is a material which is capable of interacting with said inactive catalyst material, when subjected to imaging energy, to produce an activated catalyst material and allow transmission thereof to the layer of memory material.
The method of producing an image comprising the step of providing a structure which comprises a layer of a memory material which is capable of undergoing a physical change in structure in response to energy;
