Abstract of the Disclosure, A resistive ribbon dye-donor element for resistive ribbon dye transfer is made up of a resistive support bearing a liquid lubricant containing slipping layer on one side of the resistive layer, and a conductive layer and a dye-containing layer on the other side of the resistive layer. The resistive ribbon dye-donor is brought into contact with a dye-receiving element, and a dye transfer image is formed by imagewise supplying current to the dye-donor element to resistively heat it and cause dye to be transferred to the dye-receiving element.

Why it's free to use
- Filed October 11, 1990. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 11, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 11, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
