Fluorinated-photoinitiators in dual cure resins

摘要

The present invention relates to a process for the preparation of scratch-resistant coatings by dual cure of compositions comprising surface active benzoyl compounds wherein at least one non-polar fluorinated alkyl group is present. The invention also relates to a process for concentrating these surface-active photoinitiators in the surface of coatings, to novel surface active benzoyl compounds wherein at least one non-polar fluorinated alkyl group is present, to compositions wherein the novel surface active fluorinated photoinitiators are present, and to a method for improving the flow of a curable composition on substrates.
