Abstract: 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 wherein P is selected from wherein R1, R2 and R3 are independently selected from hydrogen, alkyl, alkoxy, aryl, aralkyl, aralkoxy, halogen, and alkoxyalkoxy; wherein R4 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.

Abstract: The present invention is a novel process, with or without solvent, for manufacture of compounds of the formula 1

Abstract: The present invention is a novel process, with or without solvent, for manufacture of compounds of the formula wherein P is selected from phenyl and naphthyl; wherein R1 and R2 and R3 are each independently selected from hydrogen, alkyl, alkoxy, aryl, aralkyl, aralkoxy, halogen, alkoxyalkoxy, and aralkoxyalkoxy; wherein R5 is selected from substituted or unsubstituted phenyl, and substituted or unsubstituted naphthyl, the substituents being each independently selected from alkyl (C1-C8), alkoxy (C1-C8), aroxy, aralkoxy (C1-C8) and halogen.
