Abstract
The transfer of the invention is prepared by printing a layer onto a carrier substrate with an ink that comprises a mixture of finely subdivided polyethylene powder, an aliphatic or aromatic hydrocarbon solvent, a dispersing agent, and an additive material such as a dye or pigment indicia material and/or a physical property enhancing material such as alumina, glass beads, silica, metal flakes, etc. Preferably high and very high molecular weight polyethylene is used, alone or in mixture with lower density polyethylene in amounts from 25 to 45 weight percent in the ink. The printed layer is thermally treated to remove the hydrocarbon solvent resulting in a transfer having a carrier substrate coated with a printed layer consisting essentially of polyethylene and the additive material.
