PURPOSE: To eliminate the need of an antistatic layer by forming a dye layer on one face of a substrate and laminating an undercoating layer of a polymer of specified composition and a slipping layer successively on the other face to form a dye-donor element for thermal dye transfer. CONSTITUTION: A mixture of a polymer having a molecular weight of at least about 100,000 provided with antistatic properties and containing at least 25 wt.% of a repeated unit containing alkylene oxide segment with a copolymer having the formula is manufactured. (In the formula, A represents units of an additional polymerizable monomer containing two or more ethylenically unsaturated groups, B represents units of copolymerizable α,β-ethylenically unsaturated monomer, L represents a carboxylic group or the like, R<1> -R<3> each independently represents a C1 -C20 alkyl or the like, R<4> represents H or the like, M represents an anion, (n) represents an integer of 1-6, (x) represents 0-20 mole%, (y) represents 0-90 mole% and (z) represents 10-100 mole%). A dye layer is formed on one face of the substrate, and an undercoating layer composed of the above mixture and a slipping layer are laminated successively on the other face to form a dye-donor element for thermal dye transfer. |
