Abstract An electrophotographic process and materials for the production of multicolor copies of a multicolor original in which an electrostatic charge is applied to a receptor sheet having a face portion subdivided into photoconductive segments containing sensitizing components in interspersed segments which cover different portions of the visible light spectrum and in which each such segment contains a solubilizable dye color corresponding to the color of the spectrum other than that to which the segment is sensitized and in which the exposed receptor is developed with a toner in which the dye component is soluble in response to toner activation for transfer of dye color from the developed receptor to copy sheets brought into surface contact therewith.
The process as claimed in claim 1 in which the interspersed sections of photoconductive coatings comprise interspersed sections of three separate coating systems sensitized to the additive primary colors of red, green, blue, respectively.
Claim 2
Dependent Claim
20 words
The process as claimed in claim 1 in which the photoconductor component of the photoconductive coating comprises photoconductive zinc oxide.
Claim 3
Dependent Claim
16 words
The process as claimed in claim 1 in which the sensitizing component is a sensitizing dye.
Claim 4
Dependent Claim
63 words
The process as claimed in claim 4 in which the sensitizing dye id present in the coating in an amount within the range of 0.001 to 5.0 percent by weight when the photoconductive component is a photoconductive zinc oxide with the said percentage varying in proportion to the weight of zinc oxide and other photoconductor when said other photoconductor forms the photoconductive component.
Claim 5
Dependent Claim
21 words
The process as claimed in claim 1 in which the colored dye component corresponding to reflected light is a dispersed dye.
Claim 6
Dependent Claim
17 words
The process as claimed in claim 6 in which the dispersed dye is a spirit soluble dye.
Claim 7
Dependent Claim
43 words
The process as claimed in claim 6 in which the dye component is present in an amount within the range of 0.5 to 20 parts by weight per 100 parts by weight of the photoconductive component when that photoconductive component is zinc oxide.
Claim 8
Dependent Claim
24 words
The process as claimed in claim 1 in which the toner is an organic compound selected from the group consisting of antipyrene and 1-allyl-2-thiourea
Claim 9
Dependent Claim
61 words
The process as claimed in claim 1 in which the toner has a melting point at a temperature above ambient temperature and in which activation of the toner comprises the step of heating the coated receptor to a temperature above the melting point temperature of the toner while the copy sheet is in pressure contact with the face of the receptor.
