PROBLEM TO BE SOLVED: To obtain a heat-sensitive transfer recording material having a layer containing a specific pigment, giving recording images excellent in image storability such as fixity and light stability, improved in color tone and moisture durability and useful for thermal printers, etc. SOLUTION: This heat-sensitive transfer recording material has a layer containing one or more kinds of pigments of formulas I-IV R1 , R3 are each H, an alkyl, an aryl, a heterocyclic group; R2 is H, cyano, carbamoyl, an alkoxycarbonyl, an aryloxycarbonyl, carboxyl; X is O, CR4 (R5 ) (R4 , R5 are each an electron-attracting group); Y is N, L1 -(L2 =L3 )m [L1 -L3 are each methine; (m) is 0-2]; Z is an azo group; G1 is a heterocyclic group; Q is a non-metallic atom group required for forming a pigment having absorption wavelengths in visible and infrared regions} on a support. An image-receiving material is preferably superposed on a pigment-donating material having the pigment- donating layer containing one or more kinds of the pigments of formulas I-IV on the support and, if necessary, subsequently heating the pigment-donating material in response to image information to form the image. |
