Abstract: Radiation crosslinkable, water-dispersable polyesters and polyesteramides derived from monomer components which include dicarboxylic acids, poly(ethylene glycol), monomer components substituted with a sulfonate metal salt group and .alpha.,.beta.-unsaturated acids. A typical polyester is composed of 80 mole parts of isophthalic acid, 10 mole parts of 4-carboxycinnamic acid, 10 mole parts of 5-sodiosulfoisophthalate, and 100 mole parts diethylene glycol. The polyesters and polyesteramides may also include monomer components such as hydroxycarboxylic acid, aminocarboxylic acid, aminoalcohol, glycol, diamine or combinations of such components. Such polymers are useful as adhesives, coating materials, films, packaging materials and other products. The polymers can be dissolved, dispersed or otherwise dissipated in water or aqueous solutions, dried and subsequently cured by radiation.
