    摘要： Composite polyester films, well adapted as either thick or thin film bases, e.g., for the graphic arts or for packaging, are comprised of a crystalline or semicrystalline polyester film substrate (A), said film substrate (A) having a coating, e.g., a coextrudate, of an oxysulfonylated copolyester adhesion primer on at least one of the face surfaces thereof, and said oxysulfonylated copolyester comprising admixture of (a) a crystalline or semicrystalline polyester, and (b) an oxysulfonylated copolyester wherein the number of oxysulfonylated recurring units, relative to 100 recurring units of like monomer, range from 3 to 20, and the respective amounts of the components (a) and (b) are such that the number of oxysulfonylated recurring units in the mixture relative to the total number of recurring units of like monomer, ranges from 2 to 15%.
