Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 146 words
An imaging method comprising the steps of: a. providing an imaging member comprising a substantially electrically insulating softenable layer containing migration material, said migration material comprising a dye, said softenable layer capable of having its resistance to migration of said migration material decreased sufficiently to allow migration of said migration material in depth in said softenable layer, said softenable layer overlying a dye transfer layer which is overlying a substrate, said dye transfer layer capable of being rendered more dye receptive than said substrate; b. applying an electrical imagewise migration force to said migration material; c. developing the softenable layer by decreasing the resistance of said softenable layer to migration of the migration material at least sufficient to allow an imagewise migration of migration material to said dye transfer layer; and d. rendering said transfer layer dye receptive whereby said dye material dyes said transfer layer.
Claim 2
Dependent Claim 146 words
An imaging method comprising the steps of: a. providing an imaging member comprising a substantially electrically insulating softenable layer containing migration material, said migration material comprising a dye, said softenable layer capable of having its resistance to migration of said migration material decreased sufficiently to allow migration of said migration material in depth in said softenable layer, said softenable layer overlying a dye transfer layer which is overlying a substrate, said dye transfer layer capable of being rendered more dye receptive than said substrate; b. applying an electrical imagewise migration force to said migration material; c. developing the softenable layer by decreasing the resistance of said softenable layer to migration of the migration material at least sufficient to allow an imagewise migration of migration material to said dye transfer layer; and d. rendering said transfer layer dye receptive whereby said dye material dyes said transfer layer.
Claim 3
Dependent Claim 37 words
An imaging method according to claim 1 wherein said migration material is particles with an average particle size between 0.01 to about 2 microns and said softenable layer is between about 1/2 to about 16 microns thick.
Claim 4
Dependent Claim 28 words
An imaging method according to claim 1 wherein the step of developing by decreasing resistance to migration is accomplished by contacting said softenable layer with a solvent therefor.
Claim 5
Dependent Claim 162 words
An imaging method comprising the steps of: a. providing an imaged member comprising a layer of substantially electrically insulating softenable material and contiguous at least one surface of said softenable layer an image configuration of migration material comprising a dye receptive material, said softenable material capable of having its resistance to migration of said migration material decreased sufficiently to allow migration of said migration material in depth in said softenable material, by the method of applying an electrical imagewise migration force to migration material in a layer of substantially electrically insulating softenable material and developing said member by decreasing the resistance of said softenable material to migration of said migration material at least sufficient to allow said migration material to migrate through said softenable material in imagewise configuration; b. contacting said image contiguous surface to a dye under dye receptive conditions for said migration material; and c. removing any excess dye to leave a dyed migration image of dyed dye receptive material.
Claim 6
Dependent Claim 162 words
An imaging method comprising the steps of: a. providing an imaged member comprising a layer of substantially electrically insulating softenable material and contiguous at least one surface of said softenable layer an image configuration of migration material comprising a dye receptive material, said softenable material capable of having its resistance to migration of said migration material decreased sufficiently to allow migration of said migration material in depth in said softenable material, by the method of applying an electrical imagewise migration force to migration material in a layer of substantially electrically insulating softenable material and developing said member by decreasing the resistance of said softenable material to migration of said migration material at least sufficient to allow said migration material to migrate through said softenable material in imagewise configuration; b. contacting said image contiguous surface to a dye under dye receptive conditions for said migration material; and c. removing any excess dye to leave a dyed migration image of dyed dye receptive material.
Claim 7
Dependent Claim 39 words
An imaging method according to claim 4 wherein following step (c) said dyed dye receptive migration image contiguous surface is contacted under dye transfer conditions to a transfer member receptive to said dye to transfer a dye image thereto.
Claim 8
Dependent Claim 35 words
An imaging method according to claim 5 wherein said migration image is dyed at least once more and another dye image is transferred to a transfer member receptive to said dye under dye receptive conditions.
Claim 9
Dependent Claim 38 words
An imaging method according to claim 4 wherein said migration material is particles with an average particle size between about 0.01 to about 2 microns and said softenable layer is between about 1/2 to about 16 microns thick.
Claim 10
Dependent Claim 12 words
An imaging method according to claim 7 wherein said particles comprise gelatin.
Claim 11
Dependent Claim 29 words
An imaging method according to claim 4 wherein the step of developing by decreasing the resistance to migration is accomplished by contacting said softenable layer with a solvent therefor.
Claim 12
Dependent Claim 126 words
An imaging method comprising the steps of: a. providing an imaging member comprising a substantially electrically insulating softenable layer containing dye receptive migration material, said softenable layer capable of having its resistance to migration of said migration material decreased sufficiently to allow migration of said migration material in depth in said softenable layer; b. applying an electrical imagewise migration force to said migration material; c. developing the softenable layer by decreasing the resistance of the softenable layer to migration of the migration material through the softenable layer at least sufficient to allow an imagewise migration of migration material to a substrate; d. removing unmigrated material and softenable material; and e. contacting said migration material with a dye under dye receptive conditions for said migration material only.
Claim 13
Dependent Claim 126 words
An imaging method comprising the steps of: a. providing an imaging member comprising a substantially electrically insulating softenable layer containing dye receptive migration material, said softenable layer capable of having its resistance to migration of said migration material decreased sufficiently to allow migration of said migration material in depth in said softenable layer; b. applying an electrical imagewise migration force to said migration material; c. developing the softenable layer by decreasing the resistance of the softenable layer to migration of the migration material through the softenable layer at least sufficient to allow an imagewise migration of migration material to a substrate; d. removing unmigrated material and softenable material; and e. contacting said migration material with a dye under dye receptive conditions for said migration material only.
Claim 14
Dependent Claim 39 words
A method of claim 10 wherein excess dye is placed on said migration material and substrate and further including the step of removing said excess dye to leave an image configuration of dyed dye receptive material on said substrate.
Claim 15
Dependent Claim 27 words
An imaging method according to claim 10 wherein the developing and removing steps (c) and (d) are accomplished by contacting said softenable layer with a solvent therefor.
