A detailing agent for three-dimensional (3D) printing includes a colorant present in an amount ranging from about 1.00 wt % to about 3.00 wt % based on a total weight of the detailing agent. The colorant is a dye having substantially no absorbance in a range of 650 nm to 2500 nm. The detailing agent also includes a co-solvent, a surfactant, and a balance of water.

Provided is a dispersion liquid that enables formation of a transparent conductive film in which diffuse reflection of light by the surfaces of metal nanowires is prevented while maintaining good transparency, and in which yellow coloring is suppressed to provide the transparent conductive film with excellent external appearance. The dispersion liquid contains metal nanowires and a colored compound adsorbed onto the metal nanowires. A transmission b* value of a transparent conductive film formed from the dispersion liquid is no greater than 0.7.
