##STR00001## where R.sup.1, R.sup.2, and R.sup.3 each independently represents a hydrogen atom or a C1-C4 alkyl group; at least two of R.sup.1, R.sup.2, and R.sup.3 are C1-C4 alkyl groups; the number of carbon atoms in R.sup.1, R.sup.2, and R.sup.3 is 4 to 12 in total; and X represents an oxygen atom or an imino group.

In an example of a method for three-dimensional (3D) printing, a polymeric build material is applied to form a build material layer. A fusing agent is selectively applied, based on a 3D object model, onto the build material layer to form a patterned portion. A hydrophobic agent is selectively applied, based on the 3D object model, onto at least a portion of the patterned portion. The hydrophobic agent includes a lipophilic phase discontinuously dispersed within an aqueous phase by a surfactant, wherein the lipophilic phase includes an organosilane having a central silicon atom coupled to a C6 to C24 aliphatic or alicyclic hydro-carbon and multiple hydrolyzable groups, wherein the organosilane is present in the hydrophobic agent at from about 1 wt % to about 20 wt %. The build material layer is exposed to energy to selectively coalesce the patterned portion and form a 3D object layer having a hydrophobic portion.

A dispersion liquid includes water, a coloring material, and a dispersing resin which disperses the coloring material, in which the dispersing resin has a predetermined constituent unit A, a predetermined constituent unit B, and a predetermined constituent unit C.
