PROBLEM TO BE SOLVED: To obtain a high density of black and also a record in close to achromatic color and enable the recording in black almost free from chromatic variations due to color density by forming a coloring material layer containing plural different colors of at least, disazo color and monoazo color on a thin leaflike base material. SOLUTION: A coloring material layer containing plural colors of at least, disazo color and monoazo color is formed on a thin leaflike base material to obtain a thermosensitive transfer sheet. The disazo color is an orange color expressed by formula I (X<1> -X<4> are an H atom, a methyl group and a nitro group; and Y<1> -Y<6> are an H atom, an ethyl group and an ethoxy group). The monoazo color is a blue color expressed by formula II (Z<1> is a cyano group, a nitro group; Z<2> is an H atom, a cyano group; X<5> is a methyl group: Y<7> is a methoxy group; R<1> , R<2> are H atom, a lower alkyl group, an alkenyl group and an aryl group). |
