Abstract
Abstract An imaging method is disclosed comprising providing an imaging member comprising a first layer of softenable material containing migration material overlying a second layer of softenable material which is substantially free of migration material wherein at least one of the layers of softenable material contains a surface skin located at the interface between the layer of softenable material. This member is latently imaged and developed by softening whereby the migration material migrates through the first layer of softenable material and the interface, where the surface skin is located, and in depth in the second layer of softenable material thereby forming an imaged member. Background of the migration material is then removed from the imaged member by splitting the member at the interface thereby obtaining an image with excellent imaging properties.

Claim 1
Independent Claim
233 words
A imaging method comprising: a. providing an imaging member comprising: a first layer of softenable material containing migration material, said first layer of softenable material overlaying a second layer of softenable material, said second layer of softenable material being substantially free of migration material, at least one of said layers of softenable material containing a surface skin located at the entire surface of at least one of said softenable layers and at the interface between said layers of softenable material, said surface skin formed by exposing said surface of at least one of said layers of softenable material to hardening radiation sufficient to form said surface skin having a thickness from about 0.01 to about 00.5 micron, said layers of softenable material capable of being softened sufficiently to allow migration of migration material in depth in said layers of softenable material; b. forming an electrical latent image on said imaging member; c. developing said imaging member softening both of said first and second layers of softenable material at least sufficient to allow imagewise migration of migration material at least in depth in both of said first and second layers of softenable layers whereby said migration material migrates in image configuration through said first layer of softenable material and said interface and in depth in said second layer of softenable material; and d. removing unmigrated migration material by splitting said member at said interface.
Claim 2
Dependent Claim

A imaging method comprising: a. providing an imaging member comprising: a first layer of softenable material containing migration material, said first layer of softenable material overlaying a second layer of softenable material, said second layer of softenable material being substantially free of migration material, at least one of said layers of softenable material containing a surface skin located at the entire surface of at least one of said softenable layers and at the interface between said layers of softenable material, said surface skin formed by exposing said surface of at least one of said layers of softenable material to hardening radiation sufficient to form said surface skin having a thickness from about 0.01 to about 00.5 micron, said layers of softenable material capable of being softened sufficiently to allow migration of migration material in depth in said layers of softenable material; b. forming an electrical latent image on said imaging member; c. developing said imaging member softening both of said first and second layers of softenable material at least sufficient to allow imagewise migration of migration material at least in depth in both of said first and second layers of softenable layers whereby said migration material migrates in image configuration through said first layer of softenable material and said interface and in depth in said second layer of softenable material; and d. removing unmigrated migration material by splitting said member at said interface.
Claim 3
Dependent Claim
40 words
The method according to claim 1 wherein the migration material comprises a fracturable layer contiguous and contacting the surface of said first layer of softenable material spaced apart from the interface between said first and second layers of softenable material.
Claim 4
Dependent Claim
19 words
The method according to claim 1 wherein the migration material is dispersed throughout said first layer of softenable material.
Claim 5
Dependent Claim
12 words
The method according to claim 1 wherein the migration material is photosensitive.
Claim 6
Dependent Claim
12 words
The method according to claim 1 wherein the migration material is photoconductive.
Claim 7
Dependent Claim
15 words
The method according to claim 1 wherein said latent image is an electrostatic latent image.
Claim 8
Dependent Claim
17 words
The method according to claim 1 wherein said second layer of softenable material is on a substrate.
Claim 9
Dependent Claim
12 words
The method according to claim 7 wherein said substrate is electrically conductive.
Claim 10
Dependent Claim
33 words
The method according to claim 1 wherein development is accomplished by steps comprising exposing said imaging member to heat sufficient to soften said softenable material sufficiently to allow migration of said migration material.
Claim 11
Dependent Claim
34 words
The method according to claim 1 wherein development is accomplished by steps comprising exposing said imaging member to softening vapor sufficient to soften said softenable material sufficient to allow migration of said migration material.
Claim 12
Dependent Claim
19 words
The method according to claim 1 wherein said surface skin is from about 0.01 to about 0.2 microns thick.
Claim 13
Dependent Claim
65 words
The method according to claim 1 wherein said removing step (d) comprises the steps of: e. providing a stripping member capable of splitting said imaged formed by step (c); f. bringing said stripping member into tackified contact with said member; and g. separating said stripping member and said imaged member thereby splitting member at said interface between said first and second layers of softenable material.
