Abstract
543,940. Cellulose conversion products. KODAK, Ltd. (Eastman Kodak Co.). June 12, 1940, No. 10225. [Class 2 (ii)] [Also in Group XX] A cellulose sheet is made sensitive to light or heat by converting it superficially into a cellulose carboxylic acid by oxidation, and then converting the oxidized layer to a waterinsoluble metal salt, the term "metal" including ammonium and elements such as tellurium which form salts in the manner of a metal. In a modification cellulose fibre is oxidized and coated on a support as of paper, and the coating is converted into a water-insoluble metal salt. Such materials may be used in recording instruments of the kind in which a heated stylus replaces an inked pen ; some give a visible image when exposed under a Cooper-Hewitt quartz mercury vapour arc, or images that may be developed as with metal-hydroquinone, or a solution of hydroquinone and acetic acid, while others are photo-thermo-graphic, i.e., they yield a visible image when heated after exposure to light. In an example, paper is first bathed at room temperature in a bath of concentrated sulphuric acid and potassium dichromate to produce surface oxidation, washed, and dried. Paper so treated is already heat-sensitive. The oxidized layer is then converted into a water-insoluble metal salt of cellulose carboxylic acid by bathing in a metallic salt solution, washing and drying, the sensitivity being thereby considerably increased. Metallic salts giving good results are certain salts of silver, mercury, ammonium and iron. Less sensitive materials are produced by certain salts of bismuth, cobalt, copper, lead, manganese, thallium, tellurium and uranium. Salts of metals having an atomic weight greater than 50 are preferred. In modified examples, the paper is first treated in an oxidizing atmosphere as of nitrous fumes; or cellulose fibres are oxidized and coated, e.g. on paper, glass or a cellulose derivative film, as described in Specification 531,283, and in this case the fibres may be treated with the metallic salt solution before coating.
