Abstract: The present invention is concerned with a ribbon for non-impact printing. The ribbon comprises a transfer coating and a substrate containing resin which is a mixture of from 50% to 90% by weight polycarbonate and from 50% to 10% by weight of a block copolymer of bis-phenol A Carbonate and dimethyl siloxane, and containing from about 15% to about 40% by weight of the resin of electrically conductive carbon black.

Abstract: Organic prepolymer fillers capable of curing and reacting chemically with elastomers to form covalent bonds therewith are mixed with elastomers to form reinforcing domains with diameters of from 0.01 to about 50 microns, and when the mixture is cured, the mechanical strength of the elastomer is increased. In many cases, the thermal stability and/or the hydrolytic stability will also be increased.
