ABSTRACT:
An improved method for transferring heat transferable dyes comprises diffusing the dyes into a dye receiving element comprising a transparent layer containing an amorphous, solvent-soluble, aromatic polyester having at least 30 mole percent of its recurring units comprised of the condensation residue of a diol and a dicarboxylic acid, the residue containing a saturated gem-bivalent radical having a saturated polycyclic three-dimensional structure that includes a saturated bicyclic atomic bridged hydrocarbon ring member, the gem-bivalent radical linking two aromatic groups.
