Thermal printing ink ribbon

摘要

The present invention provides a thermal printing ink ribbon (1) wherein the transferability of the ink layer is not lowered even during high-speed printing or after storage in high-temperature environment. It also provides a thermal printing ink ribbon having a well-suited transferability even for use in end face head-type printers. The thermal printing ink ribbon (1) of the present invention comprises a release layer (3) including a copolymer containing an aromatic monomer component at a specific ratio and an ester wax on a heat-resistant base; and an ink layer (4) formed thereon by the solvent process or hot-solvent process.
