<p>A coating composition having surprisingly superior physical properties, particularly when highly-filled with small particles and bonded to a flexible film of a polymeric substrate. The composition consists essentially of 1) a homogeneous binder formed of relatively hard, high-tensile, aromatic polyester compounded with a vinylidene chloride copolymer such that the copolymer serves as means to increase the elongation and toughness and heat resistance of the binder and 2) the filler. The process of forming such a binder comprises formation of a homogeneous polymeric solution wherein each of the polymers is intimately distributed within the same solvent phase.</p> |
