Slipping layer containing amino-modified siloxane and another polysiloxane for dye-donor element used in thermal dye transfer

摘要

A dye-donor element for thermal dye transfer comprising a support having on one side thereof a dye layer and on the other side a slipping layer comprising a lubricating material in a polymeric binder, characterized in that the lubricating material comprises a linear or branched aminoalkyl-terminated poly(dialkyl, diaryl or alkylaryl siloxane) such as an amino­propyldimethyl-terminated polydimethylsiloxane or a T-structure polydimethylsiloxane with an aminoalkyl functionality at the branchpoint, and another polysiloxane, other than said aminoalkyl-terminated polysiloxane, which comprises a copolymer of a polyalkylene oxide and a methyl alkylsiloxane wherein the alkyl group has more than one carbon atom.
