Heat sensitive recording material with reverse coating

摘要

The thermosensitive recording material comprises a substrate and a sensitizer, where the substrate has thermosensitive recording layer with a dye precursor and dye acceptors on a side, and a pigment containing reverse coating on another side. The dye precursor and the dye acceptor react together under the effect of heat to form a dye. The reverse coating comprises 0.5-8.0 wt.% of a polyurethane-based cross-linking component, 75-90 wt.% of calcium carbonate as pigment and the combination of 1.0-5.0 wt.% of starch and 12-19 wt.% of styrene butadiene latex as binding agent.
