Abstract
A multi-fluid kits for three-dimensional printing can include a fusing agent and a tinted anti-coalescing agent. The fusing agent can include water and an electromagnetic radiation absorber that absorbs radiation energy and converts the radiation energy to heat. The tinted anti-coalescing agent can include an aqueous liquid vehicle, a colored dye dissolved in the aqueous liquid vehicle, and a polyelectrolyte. The polyelectrolyte can have a weight average molecular weight from about 1,000 Mw to about 8,000 Mw, the polyelectrolyte can be water-absorbent at a water to polyelectrolyte weight ratio from about 2:1 to about 1,000:1, and about 90 wt % to 100 wt % of the polyelectrolyte can be dissolved in the aqueous liquid vehicle.
