Abstract:
A polyester film constituted of a polyester resin which has an intrinsic viscosity (IV value) of 0.640-0.700, wherein the polyester resin constituting the polyester film contains a P element and further contains at least one element selected from among Mn, Mg, Ca, K, and Na elements, and when the content of the P element in the whole polyester resin is expressed by P (mol/t) and the total content of the Mn, Mg, Ca, K, and Na elements is expressed by M (mol/t), then the following relationships (1) and (2) are satisfied: 1.00≤ M−P ≤2.50  (1) 1.60≤ M/P ≤4.00  (2) A polyester film satisfactory in terms of local heat resistance, printing sensitivity, processability, and manufacturability is provided.

Claim (Index 1):
A polyester film, comprising a polyester resin having an intrinsic viscosity (IV value) of 0.640 to 0.700, wherein the polyester resin that constitutes the polyester film contains a P element and also contains at least one element of a Mn element, a Mg element, a Ca element, a K element, and a Na element, and a content P (mol/t) of the P element and a total M (mol/t) of contents of the Mn element, the Mg element, the Ca element, the K element, and the Na element in all the polyester resin satisfy the following expressions (1) and (2):\n 1.00\u2264 M\u2212P\u2264 2.50\u2003\u2003(1); and 1.60\u2264 M/P\u2264 4.00\u2003\u2003(2).
