wherein the average stanchion lengths of the encapsulated pigment ranges from 0.01 d to 3.5 d where “d” is the encapsulated pigment diameter,

wherein the stanchion-encapsulated titanium dioxide contains a polymeric encapsulating material that comprises a polymer selected from the group consisting of polyacrylate, polymethacrylate, polyalkyl(meth)acrylate, and combinations thereof,

wherein each stanchion protrudes at least two times the thickness of the encapsulating material and connects two or more particles together, and

wherein the stanchion and polymeric encapsulating material are the same material.

3. The paint composition according to claim 1 , wherein said stanchion-encapsulated titanium dioxide is 25% to 85%, by weight, titanium dioxide.

4. The paint composition according to claim 1 , wherein the pigment volume concentration (PVC) is within the range of 15% to 80%.

5. The paint composition according to claim 4 , wherein said stanchion-encapsulated titanium dioxide is 20% to 95%, by volume, of said pigment.

6. The paint composition according to claim 1 , wherein said carrier is water.

7. The paint composition according to claim 1 , wherein said binder is selected from the group consisting of acrylics, polyvinyl acetates, polyurethanes, polyesters, epoxy resins, and combinations of two or more.

8.
