Document Type and Number:
Japanese Patent JP2003519035
Kind Code:
A
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 formulawherein P is selected fromwherein 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. 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.
