Abstract
The present invention provides a curable resin composition which provides cured film having not only excellent acid resistance but also good weather resistance, good mar resistance and seal 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) 2% to 80% by weight of a polymer having hydroxyl and epoxy groups. The present invention also provides a process for forming a cured film using the resin composition.
