Abstract
"PROCEDURE FOR THE OBTAINING OF COPIES OF TEXTS OR GRAPHICS, BY THERMOCHEMICAL ACTION, UNDER INFRARED RADIATION", characterized by the fact that heat-sensitive copying paper sheets, constituted by a sensitive layer containing salts of dithiocarbonic acids or their substitutes N, heavy metal salts with the addition of amine salts or ammonium salts, whose thermosensitive sheets allow the passage of radiation, which when influencing the text or written or recorded areas of the sheet to be reproduced, placed under the thermosensitive sheet are reflected by said engraved spaces whose pigmentation acts as a screen that reverts, from a certain temperature, said radiations against the back of the thermosensitive paper causing the heat accumulated in said zones a reaction chemistry that alters the degree of transparency and color of the sheets, thermosensitive, reproduces said alteration the configuration or character of the printed or written graphic of the sheet to be reproduced.
