Abstract (en)
[origin: DE19631889A1] An ink transfer band has (a) a microporous flexible substrate; (b) one or more optional intermediate layers; and (c) one or more layers of a transfer ink. The ink transfer ribbon is characterised in that the back side of the substrate has a surface roughness depth Rt of at least approximately 400 nm and an average roughness value Ra of at least approximately 40 nm. This transfer ribbon has the advantage of solving in a simple and economical manner the problems related to oil migration and static electricity.
