Abstract
Abstract A transparency is disclosed, which is suitable for use in a multicolored xerographic reproduction process comprising a transparent, thermoplastic film sheet having at least one surface coated with a material selected from the group of long chain aliphatic hydrocarbons. The coated transparency, when used in a multicolored electrostatic copying process improves adhesion of the multicolored image thereon and permits reproduction of colors and color densities in said image which correspond well to the multicolored original copied.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
77 words
A method of xerographically preparing a color transparency copy comprising: a. forming a single color powder image of a multicolored original to be reproduced; b. transferring the powder image to a transparency comprising a thermoplastic film sheet, said sheet having at least one surface coated with a long chain aliphatic hydrocarbon having a melting point of above 40°C., the hydrocarbon coating having a thickness of above 0.1 mil; and c. fixing the powder image on the transparency.
Claim 2
Independent Claim
77 words
A method of xerographically preparing a color transparency copy comprising: a. forming a single color powder image of a multicolored original to be reproduced; b. transferring the powder image to a transparency comprising a thermoplastic film sheet, said sheet having at least one surface coated with a long chain aliphatic hydrocarbon having a melting point of above 40°C., the hydrocarbon coating having a thickness of above 0.1 mil; and c. fixing the powder image on the transparency.
Claim 3
Dependent Claim
48 words
The method of claim 1 wherein the steps of powder image formation and transfer are repeated before the fixing step, each sequence corresponding to the formation of a different color to effect multicolor reproduction, said transfer of each developed electrostatic image taking place in registration on the transparency.
Claim 4
Dependent Claim
13 words
The method of claim 1 wherein the fixing is carried out be heating.
Claim 5
Dependent Claim
25 words
The method of claim 1 wherein the transparency used in the transfer step is a thermoplastic film sheet of a polysulfone, polycarbonate, or polyester material.
Claim 6
Dependent Claim
56 words
The method of claim 1 wherein the step of forming a single color powder image comprises: a. exposing a charged photoconductive member to a filtered light image of the multicolored original to record a single color electrostatic latent image thereon; and b. developing the single color electrostatic latent image with toner particles complementary in color thereto.
Claim 7
Dependent Claim
12 words
The method of claim 1 wherein the aliphatic hydrocarbon material is octacosane.
