The present invention provides a novel linear amorphous aromatic polyester comprising units derived from (i) terephthalic acid, (ii) 1,2-propanediol or mixtures of 1,2-propanediol with up to 20 mole percent of ethylene glycol, based upon the total of 1,2-propanediol and ethylene glycol, and (iii) about 5 to 30 mole percent, based upon the total of (i), (ii), and (iii), of a glycol which contains a tertiary amine group, the amine containing glycol having a specified structure and the polyester having an inherent viscosity of about 0.05 to 0.5 dl/g when measured in 60:40 phenol:tetrachloroethane at a concentration of 0.5 g/100 ml at 25.degree. C. The novel polyester is useful as a crosslinking resin and as a photoinitiator for UV curable coating and ink compositions. Also provided is a specified ultraviolet radiation curable coating composition. The composition comprises a mixture of
