Pigment for color. Polymer in solution/dispersion to bind the pigment together and to get adhesion to substrate. Dispersing agents (surfactants) to disperse the pigment in binder solution/dispersion and to lower surface tension of the ink. Drying agent for faster drying. Rheology modifiers for viscosity control.
