摘要： A high sensitivity thermal paper resistant to image erasure is disclosed. The thermal paper has a color-forming composition comprising a chromogenic material, an acidic developer material, a water insoluble polymer consisting of poly .alpha.-methylstyrene or .alpha.-methylstyrene/vinyltoluene copolymer, and a thermal modifier. Preferably the thermal modifier is selected from acetoacet-o-toluidine, diphenoxyethane, phenyl-1-hydroxy-2-naphthoate, diheptadecyl ketone and octadecanamide. The disclosed composition when thermally imaged is surprisingly resistant to image erasure and smearing attributable to fingerprint oils.
