E2 - ETUDE DE L'AMPLIFICATION D'UNE IMPULSION MODULEE DANS LA CHAINE 100 TW DU LULI

There is disclosed a thermosensitive recording material improved in thermal response and image retention which comprises a support and, provided thereon, a thermosensitive recording layer containing a generally colorless or slightly colored dye precursor and a developer which, upon being heated, reacts with said dye precursor to develop color, wherein said thermosensitive recording layer contains as sensitizer a compound selected from a group consisting of p-benzylbiphenyl, diaryl esters of adipic acid, (wherein R represents a substituted or unsubstituted aralkyl group, (wherein R1 and R2 each represents an alkyl, aralkyl, or aryl group), and and said developer is bis(3-allyl-4-hydroxyphenyl)sulfone.
