Abstract
A surface is coated with a mixture of (i) an aliphatic, aromatic polyisocyanate such as 1,3-bis-(1-isocyanato-1-methylethyl)benzene, and (ii) a polyactive hydrogen compound such as a poly(2-hydroxyethylacrylate), and the mixture is cured under conditions such that an adherent, solid coating is formed on the surface. The coatings of the invention have surprising gloss and lack of yellowness after exposure to ultra-violet light.
