Abstract: A three-dimensional printing kit, as presented herein, can include a particulate build material and a binder agent. The particulate build material can include from about 80 wt % to 100 wt % metal particles based on the total weight of the particulate build material. The binder agent can include an aqueous liquid vehicle, an acrylic polymer or copolymer latex dispersion, a sulfonated small-molecule dispersed pigment, and a solubilized dihydrazide. A sulfonated small-molecule of the sulfonated small-molecule dispersed pigment can be from about 100 g/mol to about 2000 g/mol. The binder agent can exclude a polymeric dispersant.
