Abstract

Process of registration or reproduction on materials of the type comprising a support coated with a sensitive layer containing a chromogenic compound, characterized in that it comprises generating the colored trace by supplying thermal energy that decomposes the phenylurethane, contained on the sensitive layer, to give origin to a phenol that reacts with the chromogen compound.
