Abstract

Printing process in which a substrate to be printed is disposed opposite an ink carrier having an ink layer, the ink layer being irradiated regionally by a laser beam, said layer accelerating by absorption of the laser beam in the substrate direction, wherein for laser absorption the ink layer comprises reflective particles, a solvent, and a soluble polymer, wherein the reflective particles have an aspect ratio>25, the aspect ratio being defined as the average particle size/average particle thickness.
