  • Patent number: 7662867
    Abstract: The invention relates to the use of an infrared absorber for accelerating the UV curing of a mass to be cured. The infrared absorber is preferably selected from ATO, ITO, ZnO, LaB6 and a mixture of said substances. A casting resin is preferably used as the mass to be cured, in particular a resin based on an acrylic resin or an acrylate resin. The invention permits the production of laminated panes, in which the starting mass is applied between the panes and converted to form the laminate.

  • Patent number: 7622511
    Abstract: A method and kit for providing a tack-free artificial nail surface. The tack-free artificial nail surface may include an acrylic layer and a barrier layer. The acrylic layer may comprise an odorless monomer. The barrier layer may be of any material impervious to oxygen. The tack-free nail surface may be formed by application of the acrylic layer to a fingernail nail bed. The barrier layer may then be applied over the acrylic layer. The barrier layer blocks oxygen from the acrylic layer so that the acrylic layer may polymerize in the absence of oxygen.

  • Patent number: 7141615
    Abstract: Compositions and methods for addressing oxygen inhibition in free radical polymerization systems and determination of oxygen content in a monomer or oligomer. The compositions used include a singlet oxygen generator and a singlet oxygen trapper. Addition of the generator and trapper resulting in removal of oxygen can occur before polymerization or essentially simultaneously with polymerization. Determination of oxygen content comprises monitoring the concentration changes from the reaction of the singlet oxygen trapper with the oxygen in the system.

  • Patent number: 5902839
    Abstract: Orthopedic bone cements of low porosity, prepared by mixing together at least two liquid components under conditions that allow only minimal exposure to air, are disclosed. In a preferred system, each liquid component consists essentially of a solution of a linear (non-crosslinked) polymer or copolymer of methyl methacrylate (PMMA) dissolved in a non-crosslinking methyl methacrylate (MMA) monomer, with one such solution also containing an activator and a polymerization inhibitor and a second solution containing an initiator as well as a polymerization inhibitor. No reinforcing fillers are present, although a small amount (no more than 12% by weight of the total cement composition) of a radiopacifier may be included in the composition.

  • Patent number: 5292458
    Abstract: A method of producing a photosensitive microcapsule which contains a polymerizable monomer and a polymerization initiator. Soluble water is displaced in the polymerizable monomer by performing one or both of distilling the polymerizable monomer and adding a dehydrating agent to the polymerizable monomer. The polymerization initiator and a first microcapsule-forming material are added to the water-displaced polymerizable monomer to produce a solution. Soluble oxygen in the polymerizable monomer is displaced by performing one or both of bubbling an inert gas and adding an oxygen absorbent to the polymerizable monomer. Soluble oxygen may also be displaced in an ionic surfactant by performing the bubbling and adding of oxygen absorbent. The ionic absorbent is added to the solution containing the polymerizable monomer and polymerization initiator, and then the solution is emulsified. A microcapsule membrane is produced by adding a second microcapsule-forming material to the emulsion.

    Abstract: A method for coating a plastic lens element including applying a coating composition consisting substantially of reactants having at least triacrylate functionality, a photo-initiator and a polymerization inhibitor reactive with oxygen to the face of a mold. The coating is subjected to ultraviolet light in an oxygen containing environment such that a hard abrasion-resistant coating is formed. The mold is then filled with a lens forming composition which is reactive with acrylate groups of the coating at the coating/lens interface. The lens forming composition is permitted to cure in the mold with the lens forming composition being bonded to the lens coating.

  • Patent number: 4971895
    Abstract: A photopolymer layer is used as a radiation transparent phototool replacing a light blocking phototool in the photographic process of producing solder mask layers on printed wiring boards. Various simplification and energy reducing steps are introduced with off-contact photoprinting of patterns on liquid photopolymers having special characteristics that permit the polymerization of patterned outer skin areas partly through the thickness thereof with a controlled amount of radiation energy. This creates an in-situ surrogate phototool that permits further polymerization throughout the thickness of the layer with controlled quantities of unpatterned radiation energy. Photodiscrimination is provided by changes of photosensitivity in the layer transparent to radiation rather than by opaque imaging. Thus a first low energy photoflash through an off-contact phototool with uncollimated radiation creates on a liquid photopolymer surface two contrasting patterned areas of liquid polymer and polymerized skin.
