  • Patent number: 7326423
    Abstract: Polymerizable light absorbing azo dyes are disclosed useful as monomers in the formation of devices such as, but not limited to ocular lenses. Specifically, intraocular lenses (IOL) are disclosed wherein one or more of the light absorbing dye is covalently bonded to other structural polymers though ethylene unsaturated groups. The resulting IOLs possess light absorbing properties without significant amounts of free (un-bound) azo dye molecules present in the final structural polymer matrix.

  • Patent number: 7282555
    Abstract: The present invention is a method for efficiently incorporating a nitrogen containing methine light absorber into a polyester resin. The method includes forming a reaction mixture comprising combining a diol component, a diacid component selected from the group consisting of dicarboxylic acids, dicarboxylic acid derivatives, and mixtures thereof, an antimony containing compound, a phosphorus containing compound, a metal containing compound, and a nitrogen containing methine light absorber. The reaction mixture is polymerized in a polycondensation reaction system. In another embodiment the light absorber is added while the reaction products of one reactor are being transferred to the next reactor in the polycondensation reaction system. The present invention is also directed articles made from the polyester resin.
