Abstract
A thermosensitive recording material having high whiteness and resistance to color formation under high temperature, high humidity conditions has a thermosensitive colored image-forming layer formed on a substrate sheet and includes a dye precursor, a binder and a color developing agent including a compound of the formula (I) and optionally a compound of the formula (V). R1, R3=unsubstituted or methyl or chlorine-substituted aryl group, R2=at least C3 divalent organic group, R4=at least C3 alkyl, aralkyl or aryloxyalkyl group.
Claims5
A thermosensitive recording material comprising a substrate sheet and a thermosensitive colored image-forming layer formed on at least one surface of the substrate sheet and comprising at least one colorless or light-colored dye precursor, a color-developing agent reactive with the dye precursor upon heating to thereby develop a color, and a binder, wherein the color developing agent comprises at least one compound of the formula (I):
- wherein R1 represents a member selected from the group consisting of unsubstituted aryl groups and substituted aryl groups with at least one substituent selected from the group consisting of a methyl group and a chlorine atom, and R2 represents a divalent organic group having 3 or more carbon atoms.
