Abstract
Procedure for developing by the heat of a sensitive paper, for the reproduction of documents, whose sensitive paper is constituted by a support transparent to infrared radiation and by a sensitive layer containing a diazonium salt, a diazonium salt coupling agent and a amine in the state dispersed in, at least, a carrier material, such as an organic polymer, being able to be softened by the heat when raising the temperature, characterized in that it consists in putting said paper in contact with an original document, in such a way that the "black" parts of said document are in contact with said layer, exposing the set thus made to an infrared radiation whose spectrum has a maximum energy between 9,000 and 11,000 Å, so as to perform at least a softening of the sensitive layer and the coupling of the diazonium salt and the coupling agent faced with said parts, separating the impressed paper from the original and Ijar the image thus obtained by destroying the diazonium salt contained in the areas confronted to the "blank" parts of the original.
