Abstract
This invention relates to &agr;-ammonium ketones, iminium ketones or amidinium ketones in the form of their tetraaryl- or triarylalkylborate salts which can be photochemically converted into amines, imines or amidines as well as to a process for their preparation. This invention also relates to base-polymerisable or crosslinkable compositions comprising these &agr;-ammonium ketones, iminium ketones or amidinium ketones in the form of their tetra- or triarylalkylborate salts, to a process for carrying out photochemically induced, base-catalysed reactions as well as to their use as photoinitiators for base-catalysed reactions.
