Abstract
Abstract Transparent image-recording elements that contain ink-receptive layers that can be imaged by the application of liquid ink dots. The ink-receptive layers contain a combination of a vinyl pyrrolidone polymer with a polyester, a poly(cyclohexane-dimethylene-co-oxydiethylene isophthalate-co-sodio-sulfobenzenedicarboxylate), dispersed in the vinyl pyrrolidone to control ink dot size. A printing method which employs the transparent image-recording elements is described.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
61 words
In a transparent image-recording element comprising a support and an ink-receptive layer, said element adapted for use in a printing process where liquid ink dots are applied to the ink-receptive layer that contains a vinyl pyrrolidone polymer, the improvement wherein the layer comprises particles of a polyester, poly(cyclohexylenedimethylene-co-oxydiethylene isophthalate-co-sodiosulfobenzenedicarboxylate), dispersed in the vinyl pyrrolidone polymer to thereby control ink dot size.
Claim 2
Dependent Claim
61 words
In a transparent image-recording element comprising a support and an ink-receptive layer, said element adapted for use in a printing process where liquid ink dots are applied to the ink-receptive layer that contains a vinyl pyrrolidone polymer, the improvement wherein the layer comprises particles of a polyester, poly(cyclohexylenedimethylene-co-oxydiethylene isophthalate-co-sodiosulfobenzenedicarboxylate), dispersed in the vinyl pyrrolidone polymer to thereby control ink dot size.
Claim 3
Dependent Claim
27 words
The element of claim 1 wherein the ratio, by weight, of the polyester to the vinyl pyrrolidone polymer is in the range of about 1:1 to 6:1.
Claim 4
Dependent Claim
16 words
The element of claim 1 wherein the ink-receptive layer is about 0.004 to 0.025 mm thick.
Claim 5
Dependent Claim
16 words
The element of claim 1 wherein the particles have a diameter up to about 1 micrometer.
Claim 6
Dependent Claim

Claim 7
Dependent Claim
13 words
The element of claim 4 wherein the polyester is poly(1,4-cyclohexanedimethylene-co-2,2'-oxydiethylene (70/30) isophthalate-co-5-sodiosulfo-1,3-benzenedicarboxylate (86/14)).
Claim 8
Dependent Claim
15 words
The element of claim 1 wherein the ink-receptive layer is on a polyester film support.
Claim 9
Dependent Claim
11 words
The element of claim 7 wherein the polyester is poly(ethylene terephthalate).
Claim 10
Dependent Claim
30 words
A printing process in which liquid ink dots are applied to an ink-receptive layer of a transparent image-recording element, the improvement wherein the element is an element of claim 1.
