ABSTRACT:
The invention provides novel acrylamide functional disubstituted acetyl aryl ketones and a process for their preparation in high yields uncontaminated by difunctional material. The invention further provides photocrosslinkable compositions comprising one or more ethylenically-unsaturated monomers and as photoinitiator the acrylamide functional disubstituted acetyl aryl ketone of the invention. The compositions are useful for the preparation of films and coatings, particularly pressure-sensitive adhesive coatings.
