Abstract

1417223 Recording medium INTERNATIONAL BUSINESS MACHINES CORP 6 July 1973 [28 July 1972] 32438/73 Heading D2B [Also in Division G1] An electrolytic recording medium for use with apparatus to provide for marks to be selectively recorded on the medium either permanently or erasably (see Division Gl) comprises a porous medium, e.g. paper, impregnated with a conductive salt such as potassium fluoride, ammonium fluoride, or ammonium oxalate a reducing agent for reducing metal ions released in the medium, such as ascorbic acid stannous chloride or stannous sulphate, and an electrochromic material such as a pH indicator or a Redox system. An electrochromic material is defined as one the electromagnetic radiation absorbtion characteristics of which may be selectively altered by the influence of an electric field.
