Method of manufacturing a ribbon for non-impact printing of documents |
| abstract |
A ribbon for non-impact printing of documents of the type handled by magnetic reader/sorter apparatus comprises an electrically conductive polymer substrate and a magnetic meltable ink layer with a thin film of metal disposed between said substrate and said ink layer. The substrate consists essentially of a polycarbonate polymer containing from about 20 to about 40 percent by weight of an electrically conductive carbon black. The magnetic ink consists essentially of from about 60 to about 80 parts by weight of a solvent comprising at least one member selected from the group consisting of aliphatic alcohols having from 1 to about 5 carbon atoms, and aromatic hydrocarbons having from about 6 to about 10 carbon atoms; about 10 to about 30 parts by weight of a meltable (e.g. polyamide) polymer; from about 10 to about 30 parts by weight of a magnetic oxide; from about 1 to about 4 parts by weight of a plasticizer (e.g. an azolate, phthalate, palmitate or adipate ester); from about 0 to about 10 parts by weight of carbon black and from about 0 to about 10 parts by weight of an alcohol soluble dye. The alcohol soluble dye makes the ink useful for erasure proof printing of documents such as checks, negotiable instruments and the like. |
