Abstract
A curable composition, the cure of which can be monitored optically, comprises at least one of a hydride curable silicone, an ethylenically unsaturated compound, and a cationically polymerizable monomer, and as cure monitor dibenzofulvene or derivative thereof. The cure monitor is a latent fluorophore which reacts under the cure conditions to form a UV-detectable fluorophore. The invention also provides a method for measuring degree of cure of a polymeric material which can be a coating or an article.
