A polymerisable photoinitiator according to Formula (I):
wherein:
R1 and R2 are independently selected from the group consisting of hydrogen, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted alkynyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted alkaryl group, a substituted or
unsubstituted aryl or heteroaryl group, a halogen, an ether group, a thioether group, an aldehyde group, a ketone group, an ester group, an amide group, an amine and a nitro group;
R1 and R2 may represent the necessary atoms to form a five to eight membered ring;
L represents an n+m-valent linking group comprising 1 to 30 carbon atoms;
A represents a radically polymerizable group selected from the group consisting of an acrylate group, a methacrylate group, a styrene group, an acryl amide group, a methacryl amide group, a maleate group, a fumarate group, an itaconate group, a vinyl ether group, an allyl ether group, a vinyl ester group and an allyl ester group; and
n and m independently represent an integer from 1 to 5.
Methods for preparing the polymerisable photoinitiator and radiation curable compositions including the polymerisable photoinitiator are also disclosed.
