POLYESTER SHEET PRIMED BY A POLYESTER CONTAINING PHOSPHOROUS FOR THE PURPOSE OF BONDING PROPERTIES |
摘要 |
<p>A primer coated oriented polyester film is disclosed wherein the primer coating comprises a polyester comprising a branched chain phosphorus-containing polymer which is the reaction product of at least one dicarboxylic reactant, at least one diol or polyoxyalkylene glycol and a phosphorus acid reactant. Preferred species include isophthalic acid as the dicarboxylic reactant, diethylene glycol as the diol or polyoxyalkylene glycol and phosphoric acid as the phosphorus acid reactant. The polyester primer coating may be applied to the polyester film before or during the stretching operations. The resultant primed polyester film is found to provide excellent adhesion to many aqueous or organic solvent based printing inks subsequently applied thereto.</p> |
