Abstract

A process for preparing a paper, film or the like, heat-revealable, in order to obtain a copy of an original document, characterized in that it consists of covering on at least one face and/or impregnating it with an opaque, translucent or transparent support of a photosensitive layer, by putting said paper, film or the like, in contact with at least one aqueous liquid constituted by a solution containing in solution at least one substance capable of giving, by heating, in the presence of a developer in a latent state, which is in emulsion in said solution or in one of said aqueous liquids and which is constituted by a complex formed previously from an amine-functional compound, denominated first compound and of another of acid function, called second compound, a colored dye different from that of this substance in the absence of heat, then expelling almost all of the water from the film to cured, thus formed, so that no traces of moisture remain in said photosensitive layer.
