Recording sheets

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.

Thermal transfer recording medium

A recording medium for thermal transfer recording includes a backing, a primer layer and ink layer. The primer layer is formed on the backing. The ink layer containing a thermally fusible material is formed on the primer layer. The primer layer contains caprolactone oligomer with its number-average molecular weight of 10000 or less.
