Abstract
A method for manufacturing decorative surfaces includes, in order, the steps of a) inkjet printing an image on a first thermoplastic foil by jetting and UV curing one or more pigmented free radical UV curable inkjet inks on the first thermoplastic foil; b) applying on the inkjet printed image a second thermoplastic foil carrying a layer containing a vinylchloride-vinylacetate-vinylalcohol copolymer with the layer facing the inkjet printed image on the first thermoplastic foil; and c) heat pressing the first and second thermoplastic foils into a decorative laminate; wherein at least one of the first and second thermoplastic foils is transparent, and the one or more pigmented free radical UV curable inkjet inks contain 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.
