    Abstract: Provided herein are surface treated pigments and methods of making and using the surface treated pigments. The surface treated pigments can comprise a mineral pigment surface treated with a hydrophilic latex composition and a hydrophobic material, which produce a film on an outer surface of the pigment. The hydrophobic material can be selected from a silane, a siloxane, or a siloxane/silicone resin blend, wax, fatty acid, styrene-butadiene latex, or a mixture thereof. The hydrophilic latex composition can be selected from a straight (meth)acrylic latex emulsion, a styrene-(meth)acrylic latex emulsion, or a blend thereof. The surface treated pigment has a surface energy that is less than a surface energy of the mineral pigment alone, a water contact angle of at least 90° and a dodecane contact angle of less than 150°.
