Abstract

Improvements in an image-producing system, characterized in that it comprises a substrate that has printed, on at least part of its surface, an ink that contains a neutral or substantially neutral ink vehicle, a liquid organic base and a color former, and whose system also comprises a carrier material impregnated with a solution of an organic acid in a weakly volatile high boiling point solvent.
