Abstract
A curable coating composition comprising functionalized oligomer components i and ii which cross-link at cure to form a three-dimensional network having chains of substantially uniform, controllable molecular weight between cross-links; oligomers i and ii having weight average molecular weights not exceeding about 3,000, a polydispersity for (i) not exceeding about 1.5, and functionalities that react with one another to cross-link i and ii at cure to yield coatings with an excellent balance of hardness and mar resistance.
