摘要：
A free radical curable liquid for inkjet printing of food packaging materials comprising 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 said 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, with the proviso that 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;
with the proviso that at least one polymerizable compound B or C is present in the polymerizable composition if the free radical curable liquid contains no initiator;
wherein the polymerizable compound A has a copolymerization ratio of
with r 1 and r 2 representing the copolymerization parameters of methyl-G1 respectively methyl-G2 determined according to the method of Kelen-Tudos.
