Abstract
A thermal transfer sheet is provided which comprises a support and an ink layer formed on one side of the support. The ink layer is made of a composition of a sublimable dye and a resin binder comprised of not less than 15 parts by weight of an epoxy resin and not less than 30 parts by weight of a butyral resin. The resin binder is effective in suppressing soiling on a sheet to be transferred as will be caused by the dye additionally deposited on the background of the thermal transfer sheet during the thermal printing procedure.
