Abstract
This invention provides novel ethylenically unsaturated urethane monomers and photoreactive compositions comprising such monomers as essential constituents. The monomers can be photopolymerized or photocrosslinked and are useful in coating systems and multilayer color proofing systems. Additionally, they offer superior advantages such as significantly reduced migration between layers in multilayer color proofing systems.
