Abstract

The present invention concerns polyester resins of General Formula I (HO—[R 1 R 2 C(CH 2 —)] a [—OCOC x H y CO 2 —] b [—C p H z O—] c —H) or General Formula II (HO—[R 1 R 2 C(CH 2 —) 2 ] a [—OCOC x H y CO 2 —] b [—CH 2 CR 3 (CO 2 H)CH 2 O] d —H), wherein R 1 , R 2 , 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.
