Treated inorganic metal containing powders and polymer films containing them

A plastic article comprising a polymer and a treated pigment, wherein the treated pigment comprises:

• (a) an inorganic pigment having a surface;
• and
• (b) an organic compound comprising a fluoroalkyl group and a hydrocarbon group and having the structure:
• RH-L-RF
• wherein
• RF is a fluorochemical component containing at least one Zerewitinoff hydrogen;
• RH is selected from an aliphatic group of 1-30 carbons, cycloaliphatic group of 3-30 carbons, an aromatic group of 6-30 carbons, and a group having the structure:
• R′—(OCH2CHR″)x′—(OCH2CH2)y′—O—, wherein R′ is H or an aliphatic group of 1-20 carbons, R″ is H or methyl;
• and x′ and y′ are the same or different integers ranging from 0-20 except that the sum of x′ and y′ is at least 1 when R′ is H, and mixtures thereof;
• and
• L is selected from the group CO, isocyanate, and a mixture of polyisocyanates comprising at least three isocyanate groups, the treated pigment having the organic compound as a treatment on the surface of the pigment.
