摘要： Thermally-responsive record materials are described containing a "complex" material formed from interactions at high pH between zinc stearate and ammonia and/or zinc stearate, ammonia and zinc oxide. The use of these materials in thermally-responsive sheets improves thermal image response and/or improves resistance to thermal image decline upon exposure to elevated temperature.

摘要： A method is provided for forming stabilized admixtures of dried viable harmless lactic acid producing bacteria. A blend is prepared from a non-toxic particulate carrier and a hydrophilic molecular sieve adsorbent. Preferably the blend contains at least 95% by weight of a carrier which has a very low water absorbing capacity, and the molecular sieve adsorbent is blended in about 0.1 to 2 parts by weight for each 98 to 99.9 parts of the carrier. The resulting admixtures are storable without refrigeration.

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.
