Production of multicolored inscriptions or marks on label material e.g. for sign or label involves laser ablation downwards from top of material having substrate and 2 or more layers of different color, preferably plastics film laminate

Production of colored inscriptions or marks on label materials, which have substrate layer(s) (1) and at least 2 colored layers (2, 2') of different color, the colored layers are ablated from above downwards and at least to the top colored layer (2) by laser radiation or laser gravure in the re...

Zusammenfassung:	Production of colored inscriptions or marks on label materials, which have substrate layer(s) (1) and at least 2 colored layers (2, 2') of different color, the colored layers are ablated from above downwards and at least to the top colored layer (2) by laser radiation or laser gravure in the required areas (4, 5), so that the underlying colored layer (2', 2") or substrate (1) is exposed. An independent claim is also included for plastics film laminate with not less than 2 superimposed colored layers (2, 2') and a substrate layer (1) suitable for this purpose. Verfahren zur Herstellung von farbigen Beschriftungen oder Markierungen auf Etikettenmaterial, welches zumindest eine Trägerschicht (1) und mindestens zwei Farbschichten (2, 2') unterschiedlicher Färbung aufweist, wobei die Farbschichten (2, 2') durch Laserbestrahlung oder Lasergravur von oben nach unten in den zu beschriftenden oder zu markierenden Bereichen (4, 5) ablatiert werden, so dass jeweils darunter angeordnete Farbschichten (2', 2'') oder die Trägerschicht (1) freigelegt werden, wobei sich das Ablatieren zumindest auf die oberste Farbschicht (2) erstreckt, sowie geeignetes Kunststofffolienlaminat mit mindestens zwei übereinander angeordneten Farbschichten (2, 2') und einer Trägerschicht (1), zur Herstellung von farbigen Beschriftungen oder Markierungen, wobei das Material der Farbschichten aus Trägerpolymer, Farbpigmenten und Hilfsstoffen aufgebaut ist und durch Laserbestrahlung rückstandsfrei entfernbar ist.
