Abstract
Abstract A process for the production of a final curable resin comprising the steps of reacting a cyclopentadiene type compound with a compound having a double bond and hydroxyl group in the molecule to obtain a hydroxyl group-containing resin, reacting the thus obtained resinous polyol and at least one other polyol with a polybasic acid to obtain a hydroxyl group-containing alkyd resin and then esterifying the alkyd resin with an alpha , beta -unsaturated carboxylic acid thereby obtain the final curable resin. In one embodiment, this invention relates to said final curable resins and also to curable coating compositions containing same.
