Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
147 words
A method for the reproduction of a multicolored original, comprising: a. forming a first pattern of dry transparent unpigmented toner by developing with said toner a first electrostatic latent image of a first color in said original, transferring said first pattern of said toner to a base member, tackifying said first pattern of said toner, and applying a layer of a first colorant upon said first pattern of said toner; and b. forming at least a second pattern of dry transparent unpigmented toner by developing a second electrostatic latent image of a second color in said original, transferring said second pattern of said toner to said base member in a position relative to said first pattern which corresponds to the relative positioning of said first and second colors of said original, tackifying said second pattern, and applying a layer of a second colorant upon said second pattern.
Claim 2
Independent Claim
147 words
A method for the reproduction of a multicolored original, comprising: a. forming a first pattern of dry transparent unpigmented toner by developing with said toner a first electrostatic latent image of a first color in said original, transferring said first pattern of said toner to a base member, tackifying said first pattern of said toner, and applying a layer of a first colorant upon said first pattern of said toner; and b. forming at least a second pattern of dry transparent unpigmented toner by developing a second electrostatic latent image of a second color in said original, transferring said second pattern of said toner to said base member in a position relative to said first pattern which corresponds to the relative positioning of said first and second colors of said original, tackifying said second pattern, and applying a layer of a second colorant upon said second pattern.
Claim 3
Dependent Claim
13 words
The method of claim 1 wherein one of said two colors is black.
Claim 4
Dependent Claim
39 words
The method of claim 1 wherein said first and second electrical latent images are provided by the steps of; sequentially exposing said xerographic photoreceptor through one of two light filters, each of which transmit only one color of light.
Claim 5
Dependent Claim
14 words
The method of claim 3 wherein said base member is a panchromatic xerographic photoreceptor.
Claim 6
Dependent Claim
22 words
The method of claim 1 wherein the transparent unpigmented toner of step (a) is the same as that used in step (b).
Claim 7
Dependent Claim
16 words
The method of claim 1 wherein the tackifying steps are accomplished by heating said toned images.
Claim 8
Dependent Claim
20 words
The method of claim 1 wherein the tackifying steps are accomplished by contacting said toned image with a solvent vapor.
Claim 9
Dependent Claim
16 words
The method of claim 1 wherein the tackifying steps are accomplished simultaneously with the transferring steps.
Claim 10
Dependent Claim
14 words
The method of claim 1 wherein said base member comprises a sheet of paper.
Claim 11
Dependent Claim
13 words
The method of claim 1 wherein said base member comprises a transparent sheet.
Claim 12
Dependent Claim
25 words
The method of claim 1 wherein the transparent unpigmented toner used in step (a) has a different tackification temperature than that used in step b.
Claim 13
Dependent Claim
10 words
The method of claim 1 wherein said colorants are particulate.
Claim 14
Dependent Claim
49 words
The method of claim 1 wherein said first and second colorant layers are applied by contacting the tackified patterns of said toner with a donor layer comprised of a fracturable colorant whereby, upon removal of the donor layer, the fracturable colorant remains upon the tackified patterns of said toner.
Claim 15
Dependent Claim
34 words
The method of claim 1 further including the formation of at least a third pattern of unpigmented toner having applied thereto a layer colorant by practicing the steps recited in subparagraphs (a) or (b).
Claim 16
Dependent Claim
30 words
The method of claim 14 wherein said layer of first, second and third colorants each comprise a different color selected from the group consisting of cyan, magenta, yellow and black.
Claim 17
Dependent Claim
103 words
An electrostatically imaged member comprising: a. a support member; b. a first layer of transparent unpigmented dry toner thereon in a first image configuration and fused to said support member; c. a first colorant on said transparent unpigmented dry toner in said first image configuration; d. a second layer of transparent unpigmented dry toner in a second image configuration at least partially coincident with said first image configuration and fused to said support member and the first image where in contact therewith; and e. a second colorant, differing from said first colorant, on said transparent unpigmented dry toner in said second image configuration.
Claim 18
Dependent Claim
103 words
An electrostatically imaged member comprising: a. a support member; b. a first layer of transparent unpigmented dry toner thereon in a first image configuration and fused to said support member; c. a first colorant on said transparent unpigmented dry toner in said first image configuration; d. a second layer of transparent unpigmented dry toner in a second image configuration at least partially coincident with said first image configuration and fused to said support member and the first image where in contact therewith; and e. a second colorant, differing from said first colorant, on said transparent unpigmented dry toner in said second image configuration.
Claim 19
Dependent Claim
78 words
The imaged member of claim 16 further including: f. at least one additional layer of transparent unpigmented toner in at least one additional image configuration at least partially overlapping said first and/or second image configuration and fused to said support member and the first and/or second image where in contact therewith; and g. at least one additional colorant, different from said first and second colorants, on said transparent unpigmented toner in said at least one additional image configuration.
Claim 20
Dependent Claim
12 words
The imaged member of claim 16 wherein said support member comprises paper.
Claim 21
Dependent Claim
12 words
The imaged member of claim 16 wherein said support sheet is transparent.
Claim 22
Dependent Claim
12 words
The imaged member of claim 17 wherein said support member comprises paper.
Claim 23
Dependent Claim
12 words
The imaged member of claim 17 wherein said support sheet is transparent.
Claim 24
Dependent Claim
22 words
The imaged member of claim 16 wherein the transparent unpigmented toner of step (b) is the same as that of step (d).
Claim 25
Dependent Claim
21 words
The imaged member of claim 16 wherein the transparent unpigmented toner of step (b) is different than that of step (d).
Claim 26
Dependent Claim
22 words
The imaged member of claim 17 wherein the transparent unpigmented toner of steps (b), (d) and (f) are different from each other.
Claim 27
Dependent Claim
20 words
The imaged member of claim 17 wherein the transparent unpigmented toner of steps (b), (d) and (f) are the same.
