Patent ID: 8829083

Claim:
A coating composition comprising: (a) a dispersion comprising the melt blending of: from 20 to 70% by weight of one or more base polymers, based on the total weight of the solid content of the dispersion, wherein said one or more base polymers are one or more thermoplastic polymers selected from the group consisting of copolymers of ethylene and one or more alpha-olefins, and copolymers of propylene and one or more alpha-olefins; from 30 to 95% by weight of at least one first pigment, based on the total solid content of the dispersion, wherein said first pigment is a metal oxide selected from the group consisting of TiO 2 , SiO 2 , ZnO, Al 2 O 3 , and combinations thereof; and wherein said first pigment has an average particle size diameter in the range of from 0.1 to 1 μm; from 1 to 50% by weight of one or more stabilizing agents, based on total weight of the solid content of the dispersion; in the presence of water and one or more neutralizing agent in an extruder, wherein the content of water is from 35 to 70% by volume, based on the total volume of the dispersion, wherein said at least first one pigment is partially encapsulated by said one or more base polymers, wherein said dispersion comprises (b) a binder composition that is selected from the group consisting of acrylic latex, vinyl acrylic latex, styrene acrylic latex, vinyl acetate ethylene latex, and combinations thereof.
