Coating composition for plastic substrates and coated plastic articles

A plastic article coated with a coating composition comprising:

• (a) from about 5 to 100 percent of resin solids of a mixture of (i) a substantially saturated polyhydroxylated polydiene polymer, where at least 90 percent of the double bonds of the polydiene are hydrogenated and where the polymer has terminal hydroxyl groups, and (ii) a chlorinated polyolefin, which is a modified chlorinated polyolefin resin prepared by grafting one or more compounds selected from unsaturated polycarboxylic acids and their acid anhydrides onto a chlorinated polyolefin resin to form an acid-and/or anhydride-modified chlorinated polyolefin resin, wherein the weight of the polydiene polymer is between about 5 and 95 percent of the total weight of the mixture of polyhydroxylated polydiene polymer and chlorinated polyolefin;
• (b) about 0 to about 95 percent by weight of resin solids of a film forming polymer selected from liquid and water-reducible film forming polymers and polymeric materials selected from the group consisting of polymer emulsions, dispersions, suspensions, and solutions that upon removal of any solvents can coalesce to form a film;
• and
• (c) solvent selected from the group consisting of water and organic solvents.
