A free radical curable liquid for inkjet printing of food packaging materials includes no initiator or otherwise one or more initiators selected from the group consisting of non-polymeric di- or multifunctional initiators, oligomeric initiators, polymeric initiators, and polymerizable initiators; wherein the polymerizable composition of the liquid consists essentially of: a) 25-100 wt % of one or more polymerizable compounds A having at least one acrylate group G1 and at least one second ethylenically unsaturated polymerizable functional group G2 different from the group G1; b) 0-55 wt % of one or more polymerizable compounds B selected from the group consisting of monofunctional acrylates and difunctional acrylates; and c) 0-55 wt % of one or more polymerizable compounds C selected from the group consisting of trifunctional acrylates, tetrafunctional acrylates, pentafunctional acrylates and hexafunctional acrylates. If the weight percentage of compounds B>24 wt %, then the weight percentage of compounds C>1 wt %; and wherein all weight percentages of A, B and C are based upon the total weight of the polymerizable composition. At least one polymerizable compound B or C is present in the polymerizable composition if the free radical curable liquid contains no initiator. The polymerizable compound A has a copolymerization ratio of
