THERMAL DYE SUBLIMATION TRANSFER RECORDING ELEMENT

摘要

Thermal dye sublimation transfer recording element for receiving sublimable basic dye-precursors, comprising a support having thereon a dye-developing layer containing a dye-developing copolymer having sulfonic acid side-groups that can react with the basic dye-precursor to produce a dye image, characterized in that said dye-developing vinyl copolymer comprises plasticizing comonomers, the weight percentage of plasticizing comonomers in the dye-developing vinyl copolymer being such that the glass transition temperature of the dye-developing vinyl copolymer is between 30 DEG C and 90 DEG C.
