The invention relates to a process for the production of a multi-layer
image, preferably a multi-color image. A transfer film which is applied
to a paper ubstrate and which is treated with laser irradiation is used.
The transfer film has a laser-sensitive layer and a background layer
arranged therebeneath. The laser-sensitive layer comprises
laser-sensitive material, for example laser-sensitive pigments or other
laser-sensitive coloring agents. The laser-sensitive material in the
layer is region-wise bleached by laser irradiation. That results in a
so-called laser-induced image component. As it is transparent or partly
transparent, the background layer which is arranged therebeneath and
which can have a printed image then becomes visible from above in that
region. That therefore gives a multi-layer image which is formed by the
laser-induced image component and by the background layer jointly.
