Ink receptive coextruded film

摘要

The invention discloses an ink-based-image-bearing substrate. This substrate includes a coextruded thermoplastic film having at least one layer made from a polymer derived from polypropylene and another layer made from an acidic functional group-bearing polymer. The layer which includes the polymer derived from the polypropylene is oriented in at least the machine direction. The layer which includes the acidic function group-bearing polymer is the print-receiving layer. The acidic functional group bearing-polymer is preferably ethylene-acrylic acid or ethylene-methacrylic acid, and the acidic functional group-bearing polymer-containing layer has a softening point in a range of 180° to 220° F. Liquid toner ink is electrostatically printed on the layer which includes the acidic functional group-bearing polymer. Additionally, the invention includes a method for providing the ink-based-image-bearing substrate.
