  • Photopolymerizable compositions containing an oxonol dye
    Patent number: 8052829
    Abstract: The invention relates to photopolymerizable compositions containing an oxonol dye, which compositions cure by exposure to ultraviolet and/or visible radiation and whose visible color is substantially reduced during exposure. More particularly, the invention pertains to photopolymerizable compositions comprising a pyridin-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 a photopolymerizable composition.
    Type: Grant
    Filed: October 26, 2007
    Date of Patent: November 8, 2011
    Assignee: Dymax Corporation
    Inventors: Stephan J. W. Platzer, Patrick S. Vaughn
  • Radiation-curable fluorescing compositions
    Patent number: 7892386
    Abstract: The invention provides fluorescing compositions which cure by exposure to ultraviolet radiation and contain a europium compound which fluoresces at visible wavelengths. More particularly, the invention pertains to liquid, radiation-curable compositions comprising a substantially homogeneous fluid comprising, a fluorescing europium compound in an admixture of a polymerizable component and a polymerization initiator. Such find use as adhesives, coatings, and the like.
