PROBLEM TO BE SOLVED: To provide a photopolymerizable composition containing an oxonol dye which cures by exposure to ultraviolet and/or visible radiation and whose visible color is substantially reduced during exposure. SOLUTION: The photopolymerizable composition comprises a pyridine-2,6-dione oxonol dye in an admixture of a polymerizable component and a photopolymerization initiator. Such compositions find use as adhesives, coatings, and the like. The disappearance of the visible color of the oxonol dye acts as an indicator of full cure of the photopolymerizable composition.
