Disclosed is a method of photoinitiating conversion of a convertible reactive substrate. The initial step in this method is to unprotect the protected ketone photoinitiator species present on the substrate to form the corresponding ketone photoinitiator species for use in subsequent photoinitiated reactions in this method. At photoinitiation, ketone groups are protected by unconstituted 1,3 dioxalene groups. Also disclosed are the components used in the process, the use of protected ketone photoinitiators in photoinitiation reactions and protected ketone photoinitiators themselves. |
