ABSTRACT:
A coating composition is disclosed which is curable under the influence of ultraviolet light and which comprises a U.V.-curable binder, a photoinitiator and as accelerator a polycyclic condensation product of formaldehyde or acetaldehyde and an aliphatic or cycloaliphatic diprimary 1,2-diamine. The U.V.-curable binder is preferably an adduct containing at least one isocyanate group of (a) an acrylic or methacrylic hydroxy ester having 5 to 20 carbon atoms and (b) a polyisocyanate having 4 to 44 carbon atoms and 2 to 4 isocyanate groups.
