Release agent for thermal dye transfer.

摘要

A thermal dye transfer assemblage comprising: … …  a) a dye-donor element comprising a support having thereon a dye layer, and …  b) a dye-receiving element comprising a support having thereon a dye image-receiving layer, … the dye-receiving element being in a superposed relationship with the dye-donor element so that the dye layer is in contact with the dye image-receiving layer,… characterized in that the dye layer contains a release agent comprising:… a straight chain alkyl or polyethylene oxide perfluoroalkylated ester or perfluoroalkylated ether;… a perfluorinated alkyl-sulfonamidoalkyl acrylate copolymerized with a polyoxyethylene-4-thiaheptandioate ester;… a silicone polymer comprising units of a linear or branched alkyl or aryl siloxane;… carnauba wax;… bees wax;… polyethylene wax having a melting point of 115 DEG C or above;… an unmodified polyalkylene oxide; stearic acid;… a fatty acid amide; or mixtures thereof. The release agent aids in separating the dye-donor element from the dye-receiving element after transfer.
