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.
L'invention porte sur un procédé permettant de préparer des revêtements résistants aux rayures grâce à une double polymérisation de compositions contenant des composés tensioactifs de benzoyle, lesquels comprennent au moins un groupe alkyle fluoré non polaire. Cette invention a également trait à un procédé permettant de concentrer ces photoamorceurs tensioactifs à la surface des revêtements ; à de nouveaux composés tensioactifs de benzoyle contenant au moins un groupe alkyle fluoré non polaire ; à des compositions contenant les nouveaux photoamorceurs fluorés tensioactifs ; et à une méthode permettant d'améliorer l'écoulement d'une composition durcissable sur des substrats.
