URETHANE-COMPATIBLE POLYESTER ADHESION PROMOTERS |
| 摘要 |
The present invention concerns polyester resins of General Formula I (HO—[R1R2C(CH2—)]a[—OCOCxHyCO2—]b[—CpHzO—]c—H) or General Formula II (HO—[R1R2C(CH2—)2]a[—OCOCxHyCO2—]b[—CH2CR3(CO2H)CH2O]d—H), wherein R1, R2, a, b, c, d, x, y, p, and z are as defined herein, for use in inks and coating compositions. The polyester resins of the present invention are particularly, but not exclusively, suitable to enhance the adhesion between a printing ink or coating composition and a substrate, especially a plastic substrate, to which it is applied. The polyester adhesion promoters of the invention are compatible with urethane-based inks and coating compositions. |

1. A polyester resin according to General Formula I:
HO—[R1R2C(CH2—)]a[—OCOCxHyCO2—]b[—CpHzO—]c—H wherein: R1 and R2 are each independently selected from the group consisting of H, C1-C4alkyl, and —CH2OH; x is an integer 1 through 10; y is an integer 2 through 20; p is an integer 2 through 8; z is two times p; each CxHy and CpHz are each independently linear or branched alkyl, optionally comprising an aromatic, or saturated or unsaturated alicyclic ring; a, b, and c are each independently an integer 1 through 100; provided that b<a+c; the MW is less than 10,000; the Tg is less than 5° C.; the hydroxyl value is 225-300; and wherein the polyester resin is formed by the reaction of one or more unsaturated condensation polymers produced by a reaction of dibasic organic acids, one or more organic compounds with multiple functional groups, and one or more polyols. |
