Abstract (en)
[origin: WO02057845A1] The invention concerns a method for obtaining an electrooptic material characterised in that it consists in depositing on a substrate a solution of oligoimides whereon are grafted colouring agents capable of being oriented and in performing a treatment designed to cross-link the oligoimides and to provide orientation to the colouring agents.
