Abstract

Marking is written on plastics materials by diffusing a sublimable dye in the gaseous phase into the surface of the plastic by means of a heat source consisting of a laser beam which is dot-focussed and moveable over the trace of the desired written marks. Pref. the sublimation dye is mounted on a carrier material which is pressed against the surface of the material to be marked by means of a transparent device which allows virtually unhindered passage of the laser beam. Alternatively, the gaseous phase sublimation phase dye may be led past the point where the laser beam impinges and excess dye removed by suction and recycled.
