A smear resistant thermally reactive material for use in a one-coat system, the thermally reactive material being applied to a receiver stock and consisting essentially of: about 55-75% wax; a binder of about 0.5-11% ethylene vinyl acetate; a pigment of about 6-26% color pigment; a dye of about 0.5-14% color forming dye; and a reactant of about 5-15% epoxy resin. The smear resistant thermally reactive material has a cohesive strength that inhibits smearing of data that is thermally transferred from an ink ribbon to the receiver stock. A crosslinking polymer for use in a two-coat system is also disclosed. The crosslinking polymer has a first coating consisting of a catalyst of 100% organosilane and a second coating consisting essentially of: about 55-75% wax; a binder of about 0.5-11% ethylene vinyl acetate; a pigment of about 6-26% color pigment; a dye of about 0.5-14% color forming dye; and a reactant of about 5-15% organosiloxane. The second coating crosslinks and is thermally reactive with the first coating in order to provide a resultant coating having a cohesive strength that inhibits smearing of the resultant coating when an ink ribbon contacts or thermally reacts with the receiver stock.
