Lambson have active in examining the potential for using oligomeric photoinitiators to overcome migration issues since 1993 when research programmes were established with Professor R.S. Davidson an co-workers at Kent University and subsequently in Lambson's own labatories.

Although photopolymerization is a rather old and well established tool, numerous new applications are addled year bu year. Therefore, the development of new tailor made components for radical and cationic systems is still in progress.

In Car Refinnish bodyshops daylight bulbs/UV-A lamps are preferred for obvious safety reasons. These light sources do not expose dangerous irrediation. Recently, a robust daylight curing clearcoat based on isocyanate/thiol chemistry had been launched on the market.
Schuster an co-workers discovered that 1.4-disyanonaphthalene solutions containing an alkyltriphenylborate salt, when irradiated, yield one electron oxidation of the alkyltriphenylborate leading to carbon-boron bond clravage and formation of free alkyl radicals.

Photoinitiators for visible light curing of photopolymerizable formulations are still a challange due to the high demands in modern applications such as dental filling materials, reprography (photoresists, printing plates, integrated circuits) lasre induced 3D curing, holophorquinone and ethyl na
