Abstract
A coating for polyolefin molding compositions comprises (1) (a) from 40-90% by weight of a chlorinated polyolefin grafted with a vinyl-polymerizable monomer having a hydroxyl group at a position 15 to 40 atoms distant from the main chain of vinyl polymer grafted onto the chlorinated polyolefin, or (b) from 50 to 90% by weight of a vinyl polymer obtained by polymerizing from 5 to 40% by weight of a hydroxyl group-containing (meth)acrylate monomer having a carbon chain derived from an alcohol residue with from 6 to 18 carbon atoms, and a vinyl-polymerizable monomer having a hydroxyl group at a position 15 to 40 atoms distant from the vinyl group, wherein the vinyl polymerizable monomer is derived from the reaction product of a vinyl-polymerizable monomer having a hydroxyl group at a position 2 to 12 atoms distant from the vinyl group and a lactone, and (2) from 10 to 60 or 50% by weight of a melamine resin containing methylol, alkoxy or imino groups.
