ABSTRACT:
The invention relates to novel photoinitiators and their use in light adjustable compositions. The initiatives comprise two or more multiphoton chromophores linked by a bridging compound. The bridging compound consists of a material that is compatible with the base material of the light adjustable composition. The novel photoinitiator permit the readjustment of light adjustable material without the need for significant amounts of photoabsorbers.
