  The present invention is a novel thermally-responsive record material comprising a substrate having provided thereon in substantially contiguous relationship an electron donating dye precursor, an acidic developer material, a compound of the formula 1 wherein P is selected from 2 wherein R 1 , R 2 and R 3 are independently selected from hydrogen, alkyl, alkoxy, aryl, aralkyl, aralkoxy, halogen, and alkoxyalkoxy; wherein R 4 is independently selected from alkoxyalkyl, alkoxyalkoxy, and aralkoxyalkoxy, and a suitable binder therefor. In the context of the present invention the alkyl moieties in the alkyl, aralkyl, aralkoxy, alkoxyalkyl, alkoxyalkoxy and aralkoxyalkoxy preferably are eight carbons or less, and more preferably from one through four carbons. Substituents on aryl moieties in aryl, aralkyl, aralkoxy, and aralkoxyalkoxy groups can include hydrogen, alkyl, alkoxy and halogen. The alkyl group in these substituents also is eight carbons or less, and more preferably from one through four carbons. The thermally responsive record material of the invention has the unexpected and remarkable properties of enhanced image intensity or density, and/or improved thermal response.

  Thermally-reversible polymer compositions are obtained by reacting compounds with isocyanate and labile-hydrogen functionality. Aromatic polyimide, aromatic polycarbonate, polyarylsulfide, aromatic polyester with liquid crystal property, and polyarylimidazolidine oligomers are incorporated into the isocyanate or labile hydrogen compounds to give high-performance characteristics. Such thermally-reversible isocyanate-based polymer compositions with high-performance characteristics are useful, among other things, as finish surface coatings on composite materials such as polypropylene and polyethylene terephthalate. Novel phenolic-hydroxyl terminated polyarylsulfide and polyarylimidazolidine oligomers and their preparation are also described.
