1. A paint composition comprising a liquid carrier, binder, pigment, and additive,
wherein said pigment comprises particles of a stanchion-encapsulated pigment that is titanium dioxide and having an average of 0.2 to 6 stanchions per particle of titanium dioxide and an average stanchion length is within the range of 10 to 500 nm,
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.
