POLYESTER FILM, POLYESTER FILM FOR HEAT-SENSITIVE TRANSFER PRINTER RIBBON AND HEAT-SENSITIVE TRANSFER PRINTER RIBBON

摘要

PROBLEM TO BE SOLVED: To provide a polyester film without soiling a thermal head on being used as a base film for a heat-transfer ribbon, capable of printing without wrinkles and excellent in close adhesion of the ink, traveling property and blocking resistance.

SOLUTION: This polyester film having 1-10 μm thickness and containing a wax-based composition having ≥70°C melting point is characterized by having <0.40 static frictional coefficient of the film.
