A thermal transfer recording sheet includes a base material and, on the base material, a yellow-dye layer containing a yellow dye, a magenta-dye layer containing a magenta dye, and a cyan-dye layer containing a cyan dye. The yellow dye and the cyan dye contain compounds having specific structures.

In a thermal transfer recording sheet including a base material and a colorant layer, the colorant layer includes a yellow dye layer containing a yellow dye, a magenta dye layer containing a magenta dye, and a cyan dye layer containing a cyan dye, and the cyan dye includes a compound represented by Formula (Ia) or Formula (Ib):

##STR00001##

where R.sub.1 to R.sub.7 are substituents, X.sup. is an anion, and the compound of Formula (Ib) has at least one anionic substituent.

A thermal transfer recording sheet set includes an image-receiving sheet that includes an image-receiving layer containing a compound represented by general formula (1) or (2) and an ink sheet that includes a yellow coloring material layer containing a particular dye and a cyan coloring material layer containing a particular dye.

Provided is an aqueous ink capable of recording an image having a good hue as a magenta ink. The aqueous ink is an aqueous ink for ink jet including a first coloring material and a second coloring material. The first coloring material is a compound represented by general formula (1), and the second coloring material is a compound represented by general formula (2). A proportion (% by mass) of a content of the second coloring material to a total content of the first coloring material and the second coloring material in the aqueous ink is 0.60% by mass or more. ##STR00001##
