ABSTRACT:
Ultraviolet light curable coating compositions comprise an ultraviolet light curable component which shrinks upon curing, a component which is not significantly ultraviolet light curable and a photoinitiator. As the composition is cured by exposure to ultraviolet light, the curable component and the non-curable component phase separate and dendritic microfractures appear at phase boundaries to provide opacity to the cured coatings.
