Abstract:
The invention relates to a process for preparing triaryl organoborates proceeding from organoboronic esters in the presence of an n-valent cation 1/n Kn+, comprising the anhydrous workup of the reaction mixture and the use of the triaryl organoborates obtained as co-initiator in photopolymer formulations, holographic media and holograms.
