Abstract

A replenishable ribbon has been devised for use in high-speed printing. The ribbon consists of a 3 mil substrate of MYLAR* brand polyethylene terephthalate coated with a 2 mu Dow Silicon Resin 3140. Transferable materials adhere to resins of this type at room temperature but are released at elevated temperatures.

Self Replenishing Reusable Ribbon for High Speed Printing

A replenishable ribbon has been devised for use in high-speed printing. The ribbon consists of a 3 mil substrate of MYLAR* brand polyethylene terephthalate coated with a 2 mu Dow Silicon Resin 3140. Transferable materials adhere to resins of this type at room temperature but are released at elevated temperatures.

In this embodiment, the transfer materials are applied to the composite substrate material by use of a doctor blade (Reference U. S. Patents 3,731,146 and 3,754,963) and the transfer materials are crystal violet, Subla Print black, Subla Print orange, Subla Print blue, Subla Print yellow or mixtures thereof. Applied thickness, which is self regulating is approximately 2-5 Mu.

Transfer has been obtained at 10 ips from the best formulation by using a modulated 20 mwatt HeNe laser. The resulting image density was of the order of
