On August 11, 2022, Knocke, Frank published a patent.Application In Synthesis of 3-Amino-7-(diethylamino)-5-phenylphenazin-5-ium chloride The title of the patent was Two component system for holographic recording material mixing photopolymerizable compositions for improved storage time and other properties. And the patent contained the following:
This invention discloses a two-component system for holog. recording material mixing photopolymerizable compositions to enable a longer, improved storage time or period of use, simple and very rapid processing as well as allowing holog. elements to be produced from the recording material that have the highest possible refractive index modulation and high stability and are particularly transparent, clear and not hazy. The present invention relates to a two-component system for mixing photopolymerizable compositions and elements produced therefrom and their use. The photopolymerizable compositions are particularly useful as a recording material for optical elements with refractive index modulation, especially holograms. The experimental process involved the reaction of 3-Amino-7-(diethylamino)-5-phenylphenazin-5-ium chloride(cas: 4569-86-2).Application In Synthesis of 3-Amino-7-(diethylamino)-5-phenylphenazin-5-ium chloride
