wherein the coloring material is a dye selected from the group consisting of a methine-based dye, an azomethine-based dye, and a triphenylmethane-based dye, and
wherein the compound is represented by formula (1) or (2):

wherein, in the formula (1) and the formula (2):
R 1 and R 2 each independently represents an unsubstituted alkyl group having 1 to 8 carbon atoms;
R 3 and R 4 each independently represents a hydrogen atom, an unsubstituted alkyl group or substituted alkyl group having 1 to 8 carbon atoms, an unsubstituted alkenyl group or substituted alkenyl group having 2 to 8 carbon atoms, an unsubstituted aralkyl group or substituted aralkyl group having 7 to 12 carbon atoms, or an unsubstituted aryl group or substituted aryl group having 6 to 12 carbon atoms, or R 3 and R 4 are bonded to each other to form a nitrogen-containing heterocycle;
R 5 and R 6 each independently represents a hydrogen atom, an unsubstituted alkyl group or substituted alkyl group having 1 to 8 carbon atoms, an unsubstituted alkenyl group or substituted alkenyl group having 2 to 8 carbon atoms, an unsubstituted aralkyl group or substituted aralkyl group having 7 to 12 carbon atoms, or an unsubstituted aryl group or substituted aryl group having 6 to 12 carbon atoms, or R 5 and R 6 are bonded to each other to form a nitrogen-containing heterocycle;
a substituent in the substituted alkyl group in any one of R 3 to R 6 is a cyano group or an alkoxy group, provided that a number of carbon atoms in the substituent is excluded from the number of carbon atoms specified above;
a substituent in each of the substituted alkenyl group, the substituted aralkyl group, and the substituted aryl group each in any one of R 3 to R 6 is a functional group selected from the group consisting of an alkyl group, a cyano group, and an alkoxy group, provided that a number of carbon atoms in the substituent is excluded from the number of carbon atoms specified above; and
X − represents an anion.

2. A thermal transfer recording sheet comprising:
a substrate; and
a coloring material layer formed on the substrate,
wherein the coloring material layer contains a compound and a coloring material,
wherein the coloring material is a dye selected from the group consisting of a methine-based dye, an azomethine-based dye, and a triphenylmethane-based dye, and
wherein the compound is represented by formula (1) or (2):

wherein, in the formula (1) and the formula (2):
R 1 and R 2 each independently represents an unsubstituted alkyl group having 1 to 8 carbon atoms;
R 3 and R 4 each independently represents a hydrogen atom, an unsubstituted alkyl group or substituted alkyl group having 1 to 8 carbon atoms, an unsubstituted alkenyl group or substituted alkenyl group having 2 to 8 carbon atoms, an unsubstituted aralkyl group or substituted aralkyl group having 7 to 12 carbon atoms, or an unsubstituted aryl group or substituted aryl group having 6 to 12 carbon atoms, or R 3 and R 4 are bonded to each other to form a nitrogen-containing heterocycle;
R 5 and R 6 each independently represents a hydrogen atom, an unsubstituted alkyl group or substituted alkyl group having 1 to 8 carbon atoms, an unsubstituted alkenyl group or substituted alkenyl group having 2 to 8 carbon atoms, an unsubstituted aralkyl group or substituted aralkyl group having 7 to 12 carbon atoms, or an unsubstituted aryl group or substituted aryl group having 6 to 12 carbon atoms, or R 5 and R 6 are bonded to each other to form a nitrogen-containing heterocycle;
a substituent in the substituted alkyl group in any one of R 3 to R 6 is a cyano group or an alkoxy group, provided that a number of carbon atoms in the substituent is excluded from the number of carbon atoms specified above;
a substituent in each of the substituted alkenyl group, the substituted aralkyl group, and the substituted aryl group each in any one of R 3 to R 6 is a functional group selected from the group consisting of an alkyl group, a cyano group, and an alkoxy group, provided that a number of carbon atoms in the substituent is excluded from the number of carbon atoms specified above; and
X − represents an anion.

3. A thermal transfer recording sheet comprising:
a substrate; and
a coloring material layer and a protective layer formed on the substrate, the coloring material layer and the protective layer being formed field sequentially,
wherein the protective layer contains a compound represented by formula (1) or (2):

wherein, in the formula (1) and the formula (2):
R 1 and R 2 each independently represents an unsubstituted alkyl group having 1 to 8 carbon atoms;
R 3 and R 4 each independently represents a hydrogen atom, an unsubstituted alkyl group or substituted alkyl group having 1 to 8 carbon atoms, an unsubstituted alkenyl group or substituted alkenyl group having 2 to 8 carbon atoms, an unsubstituted aralkyl group or substituted aralkyl group having 7 to 12 carbon atoms, or an unsubstituted aryl group or substituted aryl group having 6 to 12 carbon atoms, or R 3 and R 4 are bonded to each other to form a nitrogen-containing heterocycle;
R 5 and R 6 each independently represents a hydrogen atom, an unsubstituted alkyl group or substituted alkyl group having 1 to 8 carbon atoms, an unsubstituted alkenyl group or substituted alkenyl group having 2 to 8 carbon atoms, an unsubstituted aralkyl group or substituted aralkyl group having 7 to 12 carbon atoms, or an unsubstituted aryl group or substituted aryl group having 6 to 12 carbon atoms, or R 5 and R 6 are bonded to each other to form a nitrogen-containing heterocycle;
a substituent in the substituted alkyl group in any one of R 3 to R 6 is a cyano group or an alkoxy group, provided that a number of carbon atoms in the substituent is excluded from the number of carbon atoms specified above;
