Laser imageable polyolefin film |
| 摘要 |
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. |

1. A polymeric film comprising an extruded marking layer comprising a blend of:
a. a polyolefin; b. a photochromatic pigment that forms an image after exposure to laser radiation, wherein said pigment is present in the layer in an amount of from about 11 to 60 weight percent, based on the total weight of the layer; and c. a heat diffusing additive present in the layer in an amount of from about 30 to 60 weight percent, based on the total weight of the layer; wherein said film can be marked by a laser in a wavelength range from about 300 to 10,000 nm. |
