Claims8
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.
