A process for the production of a multi-color image is described. Preferably a transfer film is used which has a laser-sensitive layer (4). The laser-sensitive layer (4) comprises a three-component mixture. The components are coloring agents which are bleachable with laser radiation, in particular pigments, for example cyan pigment, magenta pigment and yellow pigment.With the process the procedure is such that in the individual steps only a respective one of the pigment components is bleached insofar as the laser conditions which are respectively specific to the various pigment components are set. This means that in the case of the three-component mixture only a first component is bleached by laser treatment of a given location in a first step by laser irradiation and only one other component is bleached in an optional second step and only one third component is bleached in an optional third step. The color at the location in question is afforded in each case by subtractive color mixing of the remaining unbleached components.
