Abstract
The present invention provides, a curable resin composition and a process for forming a cured film therefrom wherein the cured film has not only excellent acid resistance but also good weather resistance, good mar resistance and sealer cracking resistance because of its high extensibility, The curable resin composition comprises (a) 20 to 80% by weight of a polymer having carboxyl and carboxylate groups; and (b) 20 to 80% by weight of a polymer having hydroxyl and epoxy groups.
