Abstract
Abstract Process for making novel pressure-sensitive carbons and ribbons having a resinous binder material comprising preparing a liquid composition containing a liquid polymerizable polyvinyl ester of a polyhydric alcohol, a non-volatile, non-drying oleaginous material and an imaging material, coating the liquid composition as a thin layer on a support and subjecting the thin layer to a uniform application of high intensity electron radiation for a brief period of time to cause the resin precursor to polymerize and form a thin, dry, pressure-sensitive resinous ink layer.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
25 words
The process according to claim 1 in which said oleaginous material is a liquid oil which is substantially incompatible with said solid resinous binder material.
Claim 2
Dependent Claim
39 words
The process according to claim 1 in which said composition also contains from 1 to 60 percent by weight, based on the total weight of the binder material, of an unsaturated polymer which is soluble in the liquid monomer.
Claim 3
Dependent Claim
33 words
The process according to claim 1 in which up to 10 percent by weight of the composition comprises a volatile organic solvent which is miscible with the liquid monomer and the oleaginous material.
Claim 4
Dependent Claim
36 words
The process according to claim 1 in which the irradiation step is conducted by exposing the thin layer to a high energy electron accelerator operated at a voltage of between about 100, 000 and 350,000 volts.
Claim 5
Dependent Claim
29 words
The process according to claim 1 in which the said support is a smooth casting surface from which the dried pressure-sensitive transfer layer is separated as a self-supporting element.
Claim 6
Dependent Claim
24 words
The process according to claim 1 in which the dried pressure-sensitive transfer layer has a thickness of from about 0.0005 inch to 0.005 inch.
Claim 7
Dependent Claim
12 words
A pressure-sensitive transfer element produced according to the process of claim 1.
