Dye-donor element for thermal transfer recording |
摘要 |
A thermal recording media has a base sheet, a thermal recording layer arranged on one side of the base sheet, and a back layer arranged on an opposite side of the base sheet. The back layer comprises a polyurethane having side chains derived from a fluorine-containing diol represented by the following formula ( I ) : <CHEM> wherein Rf represents a perfluoroalkyl or perfluoroalkenyl group having 1 to 20 carbon atoms; X represents a substituted or unsubstituted alkylene group having 1 to 10 carbon atoms, a substituted or unsubstituted alkenylene group represented by -CH=CH-(CH2)n- in which n stands for an integer of from 1 to 10, or <CHEM> in which n stands for an integer of from 0 to 6; Y represents a direct bond, -O-, -NH-, or -R0-NH- in which R0 is an alkylene group having 1 to 6 carbon atoms; Z represents a direct bond or -N(R')R- in which R is an alkylene group having 1 to 20 carbon atoms and R' is a hydrogen atom or an alkyl group having 1 to 6 carbon atoms; R1 and R2 each independently represent a divalent organic group; and R3 represents a residual group of an aliphatic, alicyclic or aromatic diisocyanate. |
