Abstract
A coating composition useful as an exterior finish for automobiles and trucks containing a binder and an organic carrier; wherein the binder contains A. An amine polymer of polymerized ethylenically unsaturated monomers and a polymerized constituent of the formula: ##STR1## where R.sup.1 is H or CH.sub.3, R.sup.2 is an aliphatic group and R.sup.3 is a cycloaliphatic group and the polymer has a molecular weight of about 2,000 to 50,000 and B. a blocked organic polyisocyanate.
Claims13
A coating composition comprising about 10-80% by weight of a binder and 20-90% by weight of an organic carrier;
- wherein the binder consists essentially of
- A. 30-90% by weight, based on the weight of the binder, of an amine polymer consisting essentially of polymerized ethylenically unsaturated monomers and polymerized constituent of the formula:
- ##STR7## where R.sup.1 is H, or CH.sub.3, R.sup.2 is an aliphatic group and R.sup.3 is a cycloaliphatic group;
- wherein the polymer has a weight average molecular weight of about 2,000 to 50,000;
- and
- B. 10-70% by weight of a blocked organic polyisocyanate.
