Polyester-isocyanate coatings that exhibit desirable heat resistance and adhesion to various polymeric materials and labels comprising such coatings are provided. Polyester-isocyanate compounds present in the coating can be obtained by the reaction of isocyanates with hydroxylated polyesters. The coating is applied to the label to reduce curling tendency, while improving thermal transfer printability, heat resistance, chemical resistance, scratch resistance and wave soldering resistance. |
