    摘要： A coating is obtained on a substrate by applying to the substrate a composition containing as a binder an unsaturated polyester and hardening the coating by infra-red radiation, wherein the binder is a monomer-free olefinically unsaturated polyester resin having a viscosity of 2,000 to 5,000 mPa.s at 23.degree. C. and consists essentially of the esterification reaction product of:A) 1.0 mol of an unsatured dicarboxylic acid component selected from the group consisting of maleic acid, maleic anhydride, fumaric acid and mixtures thereof,B) 0.5 to 1.2 mol of a diol component which is a dihydric alcohol with 2 to 8 carbon atoms,C) 0.5 to 1.1 mol of at least one unsaturated ether component which is a monofunctional hydroxy compound containing one or more .beta.,.gamma.-ethylenically unsaturated alkenyl ether moieties in the molecule, andD) 0 to 0.55 mol of an alcohol component which is a saturated monohydric alcohol with 4 to 10 carbon atoms.and the coating composition is useful as an automotive body repair putty.
