  • Method of preparing a photochromic optical article using an organic solvent pretreatment and photochromic coating
    Patent number: 10281628
    Abstract: A method of preparing a photochromic optical article is provided, which includes: (i) applying a first organic solvent to a surface of an optical substrate, thereby forming an organic solvent wetted surface on the optical substrate; and (ii) applying a curable photochromic coating composition over the organic solvent wetted surface of said optical substrate, thereby forming a curable photochromic coating layer over the surface of the optical substrate. The curable photochromic coating composition includes a second organic solvent, and the first and second organic solvents are miscible with each other. With some embodiments, the first and second organic solvents are the same.
    Type: Grant

  • Photochromic optical article having allophanate protective coating and process for making same
    Patent number: 9690021
    Abstract: A photochromic optical article is provided, which includes: an optical substrate; a photochromic layer over a surface of the optical substrate, wherein the photochromic layer includes a photochromic compound; and a protective layer over the photochromic layer, wherein the protective layer includes a matrix that includes residues of an ethylenically unsaturated radically polymerizable material that includes at least one allophanate group. A method of forming the photochromic optical article is also provided.
