         2 . The pre-dispersion of  claim 1 , where the silsesquioxane is a caged or partial caged structure. 
     
     
         3 . The pre-dispersion of  claim 1 , where the silsesquioxane includes one or more hydrophobic substituents and one or more hydrophilic substituents.

         5 . The dispersion of  claim 1 , where the composition includes from about 0.5 to about 40 wt % silsesquioxane, from about 0.5 to about 30 wt % dispersing agent; from about 1 to about 99 wt % curable resin. 
     
     
         6 . A dispersion composition comprising:
 (i) a silsesquioxane;   (ii) a dispersing agent;   (iii) a particulate; and   (iv) a curable resin.   
     
     
         7 . The dispersion of  claim 6 , where the silsesquioxane is a caged or partial caged structure. 
     
     
         8 . The dispersion of  claim 6 , where the silsesquioxane includes one or more hydrophobic substituents and one or more hydrophilic substituents. 
     
     
         9 . The dispersion of  claim 6 , where the dispersing agent is a hyperdispersant 
     
     
         10 . The dispersion of  claim 6 , where the particulate is a particulate filler or a pigment. 
     
     
         11 . The dispersion of  claim 10 , where the particulate is titanium dioxide or fused silica. 
     
     
         12 . The dispersion of  claim 9 , where the particulate is functionalized. 
     
     
         13 . The dispersion of  claim 6 , where the composition includes from about 0.1 to about 40 wt % silsesquioxane, from about 0.1 to about 30 wt % dispersing agent; from about 1 to about 90 wt % curable resin, and from about 1 to about 99 wt % particulate. 
     
     
         14 . A coating composition formed by combining curable monomer and a dispersion, where the dispersion includes (a) a silsesquioxane; (b) a dispersing agent; and (c) a curable resin. 
     
     
         15 . The coating composition of  claim 14 , where the dispersion further includes a particulate. 
     
     
         16 . The coating composition of  claim 14 , where the coating includes curable monomer and an initiator. 
     
     
         17 . A method for preparing a coating composition, the method comprising adding a dispersion to a coating composition, where the dispersion includes (a) a silsesquioxane; (b) a dispersing agent; and (c) a curable resin. 
     
     
         18 . The method of  claim 17 , where the dispersion further includes a particulate. 
     
     
         19 . The method of  claim 17 , where the coating includes curable monomer and an initiator. 
     
     
         20 . In combination, a silsesquioxane and a dispersing agent.
