摘要:
Prepare an oriented polymer composition having a decorative appearance by a process including extruding an orientable polymer composition from an extruder, directing the orientable polymer composition through a calibrator and then drawing the orientable polymer composition, optionally through a drawing die, at a drawing temperature to form an oriented polymer composition wherein the process further includes disposing a colorant onto a surface of the oriented polymer composition prior to the calibrator, prior to the drawing die or both prior to a calibrator and prior to the drawing die in a pattern having a width of at least five millimeters and that preferably so that the colorant is at least partially located on a recessed portion of the resulting oriented polymer composition's surface and/or extends to a depth of at least one millimeter below the oriented polymer composition's surface.
