ABSTRACT:
The present invention relates to radiation-curable compositions useful as ink vehicles or inks, in particular UV-curable inks, such as UV-litho inks, comprising a (meth)acrylated styrene allyl alcohol copolymer obtained from the (meth)acrylation of a styrene allyl alcohol (SAA) copolymer with (meth)acrylic acid and/or one or more alkyl(meth)acrylates, and at least one alkoxylated acrylated monomer.
