Abstract
The presently disclosed subject matter is directed generally to a polymeric film that comprises at least one laser imageable marking layer. The marking layer comprises a polyolefin, a photochromatic pigment, and an additive. It has been surprisingly discovered that a polyolefin film comprising a marking layer formulated with a photochromatic pigment and an additive offers a substantial advantage over prior art methods of laser imaging polyolefin films.
