Abstract

The laser beam ablatable film of the invention includes an ablatable metallic layer arranged below a translucent protective layer that is dyed through-out. The metallic layer is connected to a contrastive colored layer by a transparent connecting layer, and the contrastive colored layer is connected to a plastic film. The entire assemblage of laminated layers can also include a self-adhesive film applied to the plastic film and the self-adhesive layer is then covered by a removable carrier material. This laminated assembly can be stamped into individual labels that can be detached from the carrier material and placed onto objects. When the ablatable foil of the invention is subjected to a laser beam surface areas of the laminated assembly appear as a mixture of colors of letters or symbols resulting from the color filter effect of the protective film.
