2-(N-alkylanilino)ethyl benzoylformates 1 underwent photocyclizationvia ζ-hydrogen transfer to ketone carbonyl oxygen from charge-transfer states to give seven-membered azalactones 2 and/or 2′. The ζ-hydrogen transfer occurred regioselectively. Neither Type II products produced via γ-hydrogen trasnfer nor five-membered aminolactones produced via δ-hydrogen transfer could be detected.

A radiation curable inkjet fluid includes a radiation curable composition including at least 25 wt % of a vinylether acrylate and at least 15 wt % of a polymerizable compound including at least three acrylate groups, each wt % being based upon the total weight of the radiation curable composition; and a photoinitiator including a tertiary amine group and 0 to 3 wt % of isopropylthioxanthone based upon the total weight of the radiation curable inkjet fluid. Also, an inkjet printing method using the radiation curable inkjet fluid.
