A UV curable inkjet ink contains at least one free radical photoinitiator and at least 30 wt % of a mixture including 0 to 45 wt % of a polymerizable oligomer, at least 5 wt % of a polyfunctional propoxylated acrylate and at least 20 wt % of a monofunctional ethoxylated methacrylate according to Formula (I):
with n representing an integer of 1 to 4 and R representing an alkyl group; the weight ratio of the polyfunctional propoxylated acrylate over the monofunctional ethoxylated methacrylate is less than 1.60; and all the weight percentages wt % are based on the total weight of the UV curable inkjet ink.
