ABSTRACT:
The monoazo compound represented by formula I is excellent in compatibility with, solubility in, and coloring power for, almost all water-immiscible organic liquids, has a low melting point, and is suitable for use to color molten plastics, synthetic fiber spinning solutions, etc., and to color thermal transfer ink. ##STR1## wherein R represents sec-butyl; Cp represents a coupling component residue.
The dense solution of at least one kind of said monoazo compound in a hydrocarbon solvent diffuses and dissolves quickly and uniformly in coloring subjects such as petroleum products, and is capable of coloring fuel oil etc. to a desired distinguishable color density with small amounts.
