Abstract
Abstract A printed record in color comprises a transparent sheet on which is jet-printed subtractive color inks in layers of different color. The inked surface of the transparent sheet is adhered to the surface of an opaque backing sheet, usually white in color, so that the backing sheet reflects ambient light back through the ink layers and the transparent sheet so as to provide a color image visable through the transparent sheet that is characterized by high color density and brightness.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
121 words
A color printed record comprising: A. a sheet of flexible transparent material; B. a first thin layer of an optically clear, subtractive color, hot-melt ink adhered to selected surface portions of the transparent sheet, the ink in said first layer having a well-defined planar surface in intimate contact with the surface of said sheet; C. a flexible opaque backing sheet that is reflective to ambient light; and D. means for affixing said backing sheet flush to the inked surface of said transparent sheet so that the backing sheet reflects ambient light back through said first ink layer and the transparent sheet whereby to produce a color image visable through the transparent sheet that is characterized by high color density and brightness.
Claim 2
Dependent Claim
121 words

Claim 3
Dependent Claim
24 words
The printed record defined in claim 1 wherein the affixing means comprise an adhesive coating on one of said transparent sheet and backing sheet.
Claim 4
Dependent Claim
21 words
The printed record defined in claim 1 wherein said transparent sheet is composed of a plastic material that absorbs ultraviolet light.
Claim 5
Dependent Claim
15 words
The printed record defined in claim 1 wherein the backing sheet is ordinary white paper.
Claim 6
Dependent Claim
42 words
The printed record defined in claim 1 and further including one or more additional ink layers superimposed on said first layer at said selected sheet surface portions, the ink in each of said layers, including the first, being a subtractive color ink.
Claim 7
Dependent Claim
21 words
The printed record defined in claim 5 wherein said ink layers are applied to said transparent sheet as jetted ink droplets.
Claim 8
Dependent Claim
18 words
The printed record defined in claim 5 wherein the ink in said layers include the primary subtractive colors.
Claim 9
Dependent Claim
25 words
The printed record defined in claim 1 wherein the affixing means comprise opposite electrostratic charges on the opposing surfaces of said transparent and backing sheets.
