1. A multi-fluid kit for three-dimensional printing, comprising:
a fusing agent comprising water and a radiation absorber, wherein the radiation absorber absorbs radiation energy and converts the radiation energy to heat; and
an inkjettable fluorescing detailing agent comprising water and a fluorescent colorant that is activated by exposure to ultraviolet energy to emit light in the visible range of from about 400 nm to about 780 nm, wherein the fluorescent colorant is hexasodium-2,2′-[vinylenebis [3-sulfonato-4,1-phenylene)imino[6-(diethylamino)-1,3,5-triazine-4,2-diyl]imino]]bis(benzene-1,4-disulphonate), and wherein the multi-fluid kit is devoid of a second detailing agent and a second fluorescent colorant.
