ABSTRACT:
A new and improved thermal printing ink ribbon includes a heat-resistant base, a release layer disposed on the base including an ester wax and a rubber copolymer containing a specified aromatic monomer content and an ink layer disposed on the release layer by a solvent or hot-solvent process. The thermal printing ink ribbons exhibit satisfactory transferability even during high speed printing or after high temperature storage. The thermal printing ink ribbons are well suited for use in end face head-type printers.
