Process and composition for rapid mass production of holographic recording article

Abstract

Invention claims a composition for the production process for high performance of the obtained product comprises method. In order to a two-component polyurethane containing system-based high performance of the obtained product, for example, the polyatomic alcohol and additive is not comprise a water content is. Is the isocyanate and polyatomic alcohol, comprising a catalyst and mixing the together, and performing the degassing of to introduce the mixture of the amalgamating of all entrapped bubbles. The method for removing costs the time, wherein the air bubbles of isocyanate in the polyol mixture is that permit a polyurethane reaction solution. The process for production of the invention overcame such a method to limit, wherein of the production process for high performance of the obtained product.
