A rapid mass production of the high performance holographic recording articles including the process and composition are described. To prepare a high performance holographic recording article based on two-component urethane matrix system, for example, polyols and all the additives must be virtually free of moisture contents. Deaeration must be carried out, once isocyanate and polyols including catalysts and all other ingredients are mixed together, to eliminate all entrapped air that is introduced into the mixture during mixing. The deaeration takes time, and the urethane reaction must not be allowed to take place until all air bubbles are evacuated from the isocyanate-polyols mixture. The rapid mass production of this invention overcomes such process limitations and results in a high-volume production of the high performance holographic recording articles.
An optical article comprising a photoactive material and a polymer matrix formed by a polymerizing reaction of a material comprising component 1 and component 2, said component 1 comprises biscyclohexylmethane diisocyanate, a NCO-terminated prepolymer formed by a reaction of biscyclohexylmethane diisocyanate and polytetramethylene glycol, butyrated hydroxytoluene and a derivative of hexamethylene diisocyanate, and said component 2 comprises a polyol of polypropylene oxide and a polyol of polytetramethylene ether;
A method of manufacturing an optical article, comprising:
