  • Publication number: 20080057090
    Abstract: A film product composition that has a refractive index that matches the refractive index of the skin. The composition is made from polymers, polymers plus additives, including plasticizers, which have an average effective or actual refractive index of from 1.4 to 1.6. The refractive index of the composition matches the skin's refractive index, and therefore is helpful at masking skin fissures and imperfections such as wrinkles, cracks, abrasions and the like.

  • Publication number: 20070249764
    Abstract: Waterborne latexes are commonly used in a variety of coatings including architectural, industrial, paper, and many others. Many coatings would benefit from an incorporated optical whitening or brightening agent. Most common optical brighteners can not be incorporated directly into a water-based system due to their insufficient solubility in water. This report describes a technique for incorporating optical brighteners directly into a water-based latex system using a mini-emulsion polymerization process. Coatings made from these latexes exhibit significant optical whitening/brightening characteristics which greatly enhance the appearance of the coated substrate.
