PURPOSE: To improve bonding properties and hydrolytic stability by laminating a subbing layer composed of a specified copolymer with antistatic power and a dye layer successively on one face of a substrate to form a dye-donor element used in thermal dye transfer. CONSTITUTION: A copolymer having antistatic properties and represented by the formula is synthesized. (In the formula, A represents units of an addition polymerizable monomer containing two or more ethylenically unsaturated groups, B represents units of copolymerizable α,β-etylenically unsaturated monomer, L represents a carboxylic group or the like, R<1> , R<2> and 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%). An undercoating layer composed of the above copolymer and a dye layer are laminated successively on one face of a substrate to form a dye-donor element for thermal dye transfer. As an actual example of the substrate, a plastic film, a glassine paper, a capacitor paper or the like is used. |
