Abstract

The copy papers of the parent specification are adapted for use with data-processing machines that have magnetic or electric sensing heads by the incorporation in the donor layer of a magnetic or magnetizable material, e.g. magnetic iron oxide. The inorganic filler may then be omitted. The donor layer may also contain a material that softens the layer without dissolving it, e.g. castor oil or ricinoleic acid.
