Title (EN) NOVEL ONIUM SALTS AND THE USE THEREOF AS PHOTOINITIATORS
(FR) NOUVEAUX SELS D'ONIUM ET LEUR EMPLOI EN TANT QUE PHOTOAMORCES
Abstract:
(EN) Sulfonium, selenonium, arsonium, ammonium and phosphonium salts, useful as photoinitiators, comprise: a chromophore which absorbs visible radiation, the chromophore (1) having a removable positive hydrogen ion and (2) exhibiting a higher energy occupied molecular orbital than at least one other substituent attached to the S, Se, As, N or P atom of the salt; a group which links the chromophore to the S, Se, As, N or P atom of the salt, the group partially preventing $g(p) resonance between the chromophore and the other substituents in the salt; at least one substituent comprising an electron withdrawing group and exhibiting a lower unoccupied molecular orbital than the chromophore; and, an anion; the salts being capable, upon exposure to visible radiation, of forming a Bronsted acid.
(FR) Les sels de sulfonium, sélénonium, arsonium, amonium et phosphonium, utiles en tant que photoamorces, comprennent: un chromophore absorbant les rayonnements visibles, le chromophore (1) ayant un ion d'hydrogène positif pouvant être éliminé et (2) présentant une orbite moléculaire occupée dont l'énergie est supérieure à celle d'au moins un autre substituant fixé à l'atome S, Se, As, N ou P du sel; un groupe reliant le chromophore à l'atome S, Se, As, N ou P du sel, le groupe empêchant partiellement la résonnance $g(p) entre le chromophore et les autres substituants se trouvant dans le sel; au moins un substituant comprenant un groupe de retrait d'électrons et présentant une orbite moléculaire inoccupée inférieure à celle du chromophore; et, un anion; les sels étant capables, lors d'une exposition à un rayonnement visible, de former un acide de Bronsted.
