Antistatic subbing layer for dye-donor element used in thermal dye transfer.

摘要

Dye donor element for thermal dye transfer comprises a support, on subbing layer and a dye layer. The subbing layer comprises a copolymer of formula (I) A is addn. polymerisable monomer contg. at least 2 ethylenically unsatd. gps.; s is a copolymerisable alpha, beta-ethylenically unsatd. monomer; L is carboxylic gp. or aromatic ring; Q is N or P; R1-R3 are 1-20C (cyclo)alkyl or 6-10C (or)alkyl; R4 is H or CH3; M is anion; n is 1-6 (integer); z is 0-20 mol.%, y is 0-90 mol.%; and z is 10-100 mol.%. Also claimed is a process for forming in dye transfer image comprising: (a) imagewise heating a dye donor element as above; and (b) transferring image to dye receiving element to form transfer image. Also claimed is a thermal dye transfer assembly.
