    摘要： A method of manufacturing a Printed Circuit Board (PCB) including an inkjet printing step wherein a radiation curable inkjet ink comprising at least one polymerizable compound and at least one photoinitiator is jetted and cured on a substrate, characterized in that the at least one photoinitiator has a chemical structure according to Formula I, wherein X represents a halogen; R1 is selected from the group consisting of a substituted or unsubstituted alkyl group, a substituted and unsubstituted alkenyl group, a substituted or unsubstituted alkynyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted alkyl group and a substituted or unsubstituted aryl or heteroaryl group; R2 and R3 are independently from each other selected from the group consisting of a hydrogen, a substituted or unsubstituted alkyl group, a substituted or unsubstitited alkoxy group, a substituted or unsubstituted aryloxy group and a halogen; R1 together with R2 and R2 together with R3 may represent the necessary atoms to form a five to eight membered ring.
