Reversible heat-sensitive recording material |
摘要 |
Disclosed is a reversible heat-sensitive recording material comprising a support and a reversible heat-sensitive recording layer containing a dye precursor which is usually colorless or a pale color and a reversible color developing agent capable of causing a reversible change in color density of the dye precursor due to the difference in cooling rate after heating, and the reversible color developing agent is a compound represented by the following formula (I):wherein R1 and R2 may be the same or different from each other and each represent a C1-18 divalent hydrocarbon group; R3 represents a C1-24 hydrocarbon group; X1 represents a divalent connecting group having at least one -CONH- bonding; X2 represents an oxygen atom or a sulfur atom; n is an integer of 1 to 3; and m is 0 or 1.
