Title
(EN) PHOTOCHROMIC MATERIAL FOR ELECTRO-OPTIC STORAGE MEMORY
(FR) MATERIAU PHOTOCHROME POUR MEMOIRE ELECTRO-OPTIQUE
Abstract
(EN)
The present invention relates to the field of photochromic material, in particular of photochromic compounds and matrices suitable for use in optical memory systems, including three dimensional optical memory systems for computers, multimedia applications and the like. The photochromic compounds have formula (1), wherein the substituents are defined in the specification.
(FR)
Cette invention, qui relève du domaine des matériaux photochromes, porte notamment sur des composés photochromes et des matrices les comportant, propres à une utilisation dans des mémoires optiques, y compris dans des mémoires optiques tridimensionnelles pour ordinateurs ainsi que dans des applications relevant des multimédias et analogue. Ces composés photochromes répondent à la formule (1), dans laquelle les substituants sont tels que définis dans la description.
