Abstract
A liquid polycarbonate coating composition including an aliphatic polycarbonate resin and a cross linking compound, said aliphatic polycarbonate resin being derived from, in the presence of a catalyst, an aliphatic polyol which comprises (a) from 50 to 100% by weight of the aliphatic polyol, one or more cycloaliphatic polyols that consist essentially of primary hydroxyl groups and (b) from 0 to 50% by weight of the aliphatic polyol, one or more linear aliphatic polyols, is provided. A method of coating a substrate with the liquid polycarbonate coating composition and the resulting articles are also provided.
