Abstract
The present invention relates to the field of optical recording materials, in particular, fluorescent compounds and matrices suitable for use in optical memory systems, including three dimensional optical memory systems for READ ONLY MEMORY (ROM). More particularly, nonfluorescent peri-phenoxiderivatives of polycyclic quinones are transformed into fluorescent aminoderivatives of anaquinones.
