摘要： A polymerizable photoinitiator represented by Formula (I): and wherein R1, R2 and R3 are independently selected from the group consisting of a hydrogen, an optionally substituted alkyl group and an optionally substituted aryl group or R1 and R3 represent the necessary atoms to form a five to eight membered ring; p, w, y and z are all integers with y representing a value 1 to 6; p representing the sum of w and z; p representing a value of 1 to 6; w = 1 to (p-z) and z = 0 to (p-w); L represents an optionally substituted (p+y)-valent linking group comprising 1 to 14 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, an allyl ester group and a vinyl ester group; and X represents a photoinitiating moiety including at least one group capable of initiating a free radical polymerization reaction upon exposure to actinic radiation. Radiation curable compositions including the polymerizable photoinitiator and methods of preparing the polymerizable photoinitiator are also disclosed.
