Abstract
Abstract A migration imaging system wherein migration imaging members typically comprising a substrate, a layer of softenable material, and migration marking material, additionally contain one or more overlayers of material to produce improved results in the imaging system. The overlayer may variously comprise another layer of softenable material, a layer of material which is harder than the softenable material layer, or a gelatin layer.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
75 words
AN IMAGENED COMPRIDING A SUBSTRATE, A SUBSTRATE, A LAYER OF ELECTRICAL INSULATING MATERIAL, ALAYER CONSISTING OF GELATIN OVERLYING SAID LAYER OF SOFTENABLE MATERIAL AND AGGLOMARABLE MATERIAL MAKING DISTRIBUTED IN DEPTH IN SAID SOFTENABLE MATERIAL IN A FIRST IMAGE CONFURATION WITH SAID FIRST IMAGE CONFIGURATION OF AGGLOMERABLE MATERIAL AGGLOMERATED AND/OR FUSED COMPRISING IN ADDITION TO SAID FIRST IMAGE CONFIGURATION, AN UNAGGLOMERATED COMPLEMENTARY BACKGROUND PATTERN OF AGGLOMERABLE MIGRATION MARKING MATERIAL REMAINING SUBSTANTIALLY UNAGGLOMERATED CONTACTING THE GELATIN LAYER-INTERFACE.
Claim 2
Dependent Claim
75 words
AN IMAGENED COMPRIDING A SUBSTRATE, A SUBSTRATE, A LAYER OF ELECTRICAL INSULATING MATERIAL, ALAYER CONSISTING OF GELATIN OVERLYING SAID LAYER OF SOFTENABLE MATERIAL AND AGGLOMARABLE MATERIAL MAKING DISTRIBUTED IN DEPTH IN SAID SOFTENABLE MATERIAL IN A FIRST IMAGE CONFURATION WITH SAID FIRST IMAGE CONFIGURATION OF AGGLOMERABLE MATERIAL AGGLOMERATED AND/OR FUSED COMPRISING IN ADDITION TO SAID FIRST IMAGE CONFIGURATION, AN UNAGGLOMERATED COMPLEMENTARY BACKGROUND PATTERN OF AGGLOMERABLE MIGRATION MARKING MATERIAL REMAINING SUBSTANTIALLY UNAGGLOMERATED CONTACTING THE GELATIN LAYER-INTERFACE.
Claim 3
Dependent Claim
14 words
The imaged member of claim 1 wherein said layer of gelatin is substantially transparent.
Claim 4
Dependent Claim
23 words
The imaged member of claim 1 wherein said layer of gelatin is a thickness in the range not greater than about 75 microns.
Claim 5
Dependent Claim
22 words
The imaged member of claim 1 wherein said layer of gelatin is a thickness of from about 0.01 to about 1.0 microns.
Claim 6
Dependent Claim
22 words
The imaged member of claim 1 wherein said layer of gelatin is a thickness of from about 0.1 to about 0.5 microns.
Claim 7
Dependent Claim
26 words
The imaged member of claim 1 wherein the layer of gelatin comprises photographic grade gelatin with a molecular weight ranging from about 20,000 to about 100,000.
Claim 8
Dependent Claim
20 words
The imaged member of claim 1 wherein said layer of gelatin is of a hardness greater than the softenable material.
Claim 9
Dependent Claim
16 words

Claim 10
Dependent Claim
14 words
The imaged member of claim 8 wherein said electrically photosensitive material is vitreous selenium.
Claim 11
Dependent Claim
36 words
The imaged member of claim 1 comprising a second overlayer of material overlying said layer of gelatin, said second overlayer being harder than said softenable layer and of such construction as to permit charge transport therethrough.
Claim 12
Dependent Claim
15 words
The imaged member of claim 10 wherein the second overlayer of material is substantially transparent.
