ABSTRACT:
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, 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.
