Abstract
The present invention provides a curable coating composition comprising PA1 (a) a first component comprising at least two functional groups, at least one of which is a carbamate or urea group that is the reaction product of: PA2 (1) a hydroxyl group that is the result of a ring-opening reaction between an epoxy group and an organic acid group, and PA2 (2) cyanic acid or a carbamate or urea group; PA1 (b) a curing agent having a plurality of functional groups that are reactive with component (a), and PA1 (c) a second component having functional groups that are reactive with component (a) or component (b) or both components (a) and (b).
