Abstract
An inkjet printing method for decorative surfaces includes jetting an image on a first thermoplastic foil with one or more pigmented free radical UV curable inkjet inks, at least partially UV curing the jetted image on the first thermoplastic foil, inserting a layer containing a vinylchloride-vinylacetate-vinylalcohol copolymer between a second thermoplastic foil and the first thermoplastic foil with the at least partially UV cured image facing the layer containing the vinylchloride-vinylacetate-vinylalcohol copolymer. At least one of the first and second thermoplastic foils is a transparent thermoplastic foil. The one or more pigmented free radical UV curable inkjet inks contains a polymerizable composition having 30 to 90 wt % of one or more compounds with one ethylenically unsaturated polymerizable group; 10 to 70 wt % of one or more compounds with two ethylenically unsaturated polymerizable groups; and 0 to 10 wt % of one or more compounds with three or more ethylenically unsaturated polymerizable groups.
