    摘要： A free radical curable liquid for inkjet printing of food packaging materials comprising no initiator,
    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 selected from the group consisting of a vinlyether group, an allylether group and a allylester group;
    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; and
    with the proviso that at least one polymerizable compound B or C is present in the polymerizable composition.

    摘要： A lithographic printing plate precursor is provided which comprises an aluminum support having a hydrophilic surface and a coating provided thereon, said coating comprising a photopolymerisable composition having a polymerisable compound, a pigment dispersed with a dispersant, a polymerization initiator and a binder, characterized in that the dispersant is a compound free of -COOH, - PO 3 H 2 or -OPO 3 H 2 groups, and the polymerization initiator is a trihalomethyl-aryl sulphone wherein the aryl group is substituted by at least one electron-donating group and wherein the sum of the Hammett constants (sigma) of the substituting groups on said aryl group has a negative value.
    The printing plate precursor exhibits an excellent daylight stability and shelf-life.
