Abstract

Die Erfindung betrifft ein Polyolefin zur Laserbeschriftung enthaltend, bezogen auf die Gesamtmenge, 0,2 bis 10 Gew% eines Zusatzstoffes, ausgewählt aus der Gruppe Silikate und Siliciumdioxid mit einer Teilchengröße von 0,01 bis 100 µm. Die Erfindung umfaßt weiterhin ein Masterbatch aus diesem Polyolefin sowie ein Verfahren zur Herstellung laserbeschrifteter Formkörper oder Folien durch Bestrahlung mit einem CO2-Laser.The invention relates to a polyolefin for laser marking containing, based on the total amount, 0.2 to 10% by weight of an additive selected from the group consisting of silicates and silicon dioxide with a particle size of 0.01 to 100 μm. The invention further comprises a masterbatch made from this polyolefin and a method for producing laser-inscribed moldings or foils by irradiation with a CO 2 laser.
