The invention relates to organic compounds having a molecular weight of less than 1000 comprising at least one structural unit of the formula (I)
1
in which R
1
is an aromatic or heteroaromatic radical which is capable of absorbing light in the wavelength range from 200 to 650 nm and in doing so brings about cleavage of the adjacent carbon-nitrogen bond.
The compounds represent photoinitiators for base-catalyzable reactions. Other subjects of the invention are base-polymerizable or crosslinkable compositions comprising compounds having a structural unit of the formula 1, a method of implementing photochemically induced, base-catalyzed reactions, and the use of the compounds as photoinitiators for base-catalyzed reactions.
