Abstract
Disclosed herein are thermosetting coating compositions comprising high Tg acrylic polymers which are substantially free of crosslinking groups, in combination with melamine resins in small but effective amounts to produce drawable cured coatings. These coating compositions are particularly useful in can coating where stringent fabricating properties and high film integrity are conjointly required.
