Abstract
A radiation curable inkjet ink set comprising a cyan inkjet ink containing a beta-copper phthalocyanine pigment and a polymerizable composition; a magenta inkjet ink containing a magenta or red pigment and a polymerizable composition; a yellow inkjet ink containing a yellow pigment and a polymerizable composition; and a black inkjet ink containing a carbon black pigment and a polymerizable composition; wherein the polymerizable compositions of the cyan, magenta, yellow and black inkjet inks include on average: a) 20.0 to 40.0 wt % of phenoxyethyl acrylate; b) 23.0 to 32.0 wt % of isobornyl acrylate; c) 1.0 to 14.4 wt % of monomer selected from the group consisting of 4-acryloylmorpholine and a monomer according to Formula (I), wherein X represents C or O, n represents 1, 2 or 3 and m represents 0 or 1; and d) up to 14.0 wt % of a multifunctional monomer or oligomer; wherein all weight percentages (wt %) are based upon the total weight of the inkjet ink; and wherein 0, 1 or 2 of the cyan, magenta, yellow and black inkjet inks deviate in a range a) to d) and this deviation is no more than 1.0 wt %.
