<p>This invention relates to toner receptive topcoats having improved fusion and anchorage of color toners. The formulations comprise a polymeric binder and, optionally, at least one functional additive. In one embodiment, the invention relates to an aqueous topcoat composition comprising a major amount of a solvent and a minor amount of a polymeric binder in order to obtain a toner adhesion rating of greater than or equal to about 15 g in the BYK-Gardner test. The invention also relates to printable substrates having a topcoat which improves adhesion of toner. Methods of making the topcoated printable substrate is also included herein. The topcoats provide increased toner anchorage, especially color toner anchorage. The topcoat is particularly effective in providing improved toner anchorage to thick facestocks.</p> |
