Abstract: A multi-fluid kit for three-dimensional printing can include a fusing agent and a detailing agent. The fusing agent can include water and a radiation absorber. The radiation absorber absorbs radiation energy and converts the radiation energy to heat. The detailing agent includes a lipophilic phase discontinuously dispersed within an aqueous phase by a surfactant. The lipophilic phase includes an organosilane having a central silicon atom coupled to a C6 to C24 aliphatic or alicyclic hydrocarbon and multiple hydrolyzable groups. The organosilane is present in the detailing agent at from about 1 wt % to about 20 wt %.
