Abstract: Unsatd. polyester based binders are made by (1) in a first stage, reacting (a) >=1 single olefinically unsatd. dicarboxylic acid which is free from polymerisable aliphatic multiple bonds; (I); (b) >=1 polyhydric alcohol (II) and (c) >=1 polycyclic norbornane ring cpd. (III) with >=1 functional COOH, OH or amino gp., and (2) in a second stage, reacting the prod. with (d) >=1 condensable acrylic cpd. (IV). The modified acrylated polyesters are esp. useful as binders for UV-curable printing inks. The norbornane ring modification gives prods. with improved processability and improved storage stability in pigmented form. The binders have good pigment wetting characteristics, fast cure times and low viscosity and thus give fast drying high gloss prints with freedom from 'picking' (sticking of paper to the printing rollers).
