HEAT-SENSITIVE RECORDING MATERIAL WITH REVERSE FACE COATING

摘要

A heat-sensitive recording material having a substrate that carries on its first side at least one heat-sensitive recording layer having at least one dye precursor and at least one color acceptor. The dye precursor and color acceptor react with one another in a color-forming manner under the action of heat. On its second side the substrate has a backcoat containing calcium carbonate. The backcoat is formed of at least two layers, a first layer is applied closer to the substrate and a second layer is applied farther from the substrate. The first layer contains a first calcium carbonate and the second layer contains a second calcium carbonate that differs from the first calcium carbonate.
