Abstract
The present invention relates to a radiation curable composition comprising at least one ethylenically unsaturated compound (A) and at least one inert OH-terminated polyester (B) prepared from a polyol component that comprises ethylene glycol and from a polycarboxy component that comprises phthalic acid and/or phthalic anhydride. These polyesters can be further modified to bear moieties comprising photo-initiating activity. The present invention further relates to their preparation and their use in for instance lithographic and flexographic applications.
