Abstract
Holographic articles having self-sealing properties such as moisture resistance and environmental durability are disclosed. The holographic articles are formed by the reaction of a composition containing an excess amount (i.e. non-stoichiometric amount) of polyisocyanates to polyols. The holographic recording articles exhibit high optical clarity and low scattering.
Claims27
An optical article comprising a photoactive material dispersed in a polymer formed by a polymerizing reaction of a composition comprising a stoichiometrically excess amount of a polyisocyanate to a polyol, wherein the optical article is self-sealing and the optical article is selected from the group consisting of an optical waveguide and a holographic recording medium and combinations thereof.
An optical article comprising a photoactive material dispersed in a polymer formed by a polymerizing reaction of a composition comprising a stoichiometrically excess amount of a polyisocyanate to a polyol, wherein the optical article is self-sealing, wherein said polyol comprises a fluorine-containing polyol.
A method for self-sealing an optical article comprising exposing the optical article to water and forming polyurea, the optical article comprising a photoactive material dispersed in a polymer formed by a polymerizing reaction of a composition comprising a stoichiometrically excess amount of a polyisocyanate to a polyol and the optical article is selected from the group consisting of an optical waveguide and a holographic recording medium and combinations thereof.
A method for self-sealing an optical article comprising exposing the optical article to water and forming polyurea, the optical article comprising a photoactive material dispersed in a polymer formed by a polymerizing reaction of a composition comprising a stoichiometrically excess amount of a polyisocyanate to a polyol, wherein said polyol comprises a fluorine-containing polyol.
A method for manufacturing an optical article comprising dispersing a photoactive material in a composition comprising a stoichiometrically excess amount of a polyisocyanate to a polyol, polymerizing the polyisocyanate and the polyol, and forming the optical article, wherein the optical article is self-sealing and the optical article is selected from the group consisting of an optical waveguide and a holographic recording medium and combinations thereof.
A method for manufacturing an optical article comprising dispersing a photoactive material in a composition comprising a stoichiometrically excess amount of a polyisocyanate to a polyol, polymerizing the polyisocyanate and the polyol, and forming the optical article, wherein the optical article is self-sealing, wherein said polyol comprises a fluorine-containing polyol.
