Polyester-polyamines were prepared to improve the effect on dispersibility of carbon black used for thermal transfer ink. The synthesis of polymeric dispersing agents was completed by two step reactions; initially, polyester was made by polycondensation of 1,6-hexanediol and adipic acid. The resulting polymers having carboxylic acid were linked with polyamine via acid-base reaction. The structure of the polyesterpolyamine was characterized by NMR spectroscopy and Fourier transform infrared spectroscopy (FT-IR). Basic characterizations such as total acid numbers (TAN) (5.0 - 67.5 mgKOH/g), hydroxyl values (27.1 - 67.5 mgKOH/g), and molar masses (Mn = 1.6 - 8.4 kg mol<SUP>-1</SUP>) for the polyester and total base numbers (TBN)(15.3 - 57.1 mgKOH/g), hydroxyl values (33.0 - 79.8 mgKOH/g), and nitrogen contents (1.02 - 3.48%) for the polyester-polyamine were also determined. Thermal transfer inks were prepared with carbon blacks and the polyester-polyamine dispersing agents, and the resulting mixtures were evaluated for printability, adhesive force, storage stability, ink appearance, ink gloss, and processability, showing significant dispersibility for carbon black in the ink. It can be concluded that the dispersibility of the polymeric materials was dependent on the structure of polyamine and the hydrophilicity-hydrophobicity distribution of the polymeric dispersants.
