Summary:A coating composition may include a polyol, a silsesquioxane, a polyurethane dendrimer, a crosslinker, and a pigment in contact with a dispersing agent. A process for preparing a coating composition is further disclosed including the step of contacting a polyol, a silsesquioxane, a polyurethane dendrimer, and a crosslinker to form a coating mixture dispersed within a solvent. The process further includes adding a pigment in contact with a dispersing agent to the coating mixture, and forming a self-stratifying coating having at least one layer, wherein the pigment resides substantially within one of the at least one layer.
