1. A method for manufacturing decorative surfaces including the steps of:
inkjet printing an image on a first thermoplastic foil by jetting and curing one or more pigmented free radical curable inkjet inks on the first thermoplastic foil;
applying and curing a free radical curable liquid as an adhesive layer on the inkjet printed image; and
heat pressing the first thermoplastic foil with a second thermoplastic foil into a decorative laminate,
wherein at least one of the first and second thermoplastic foils is a transparent thermoplastic foil;
wherein the one or more pigmented free radical curable inkjet inks include a colour pigment and a polymerizable composition containing 10 to 90 wt % of one or more monofunctional polymerizable compounds;
wherein the free radical curable liquid includes a polymerizable composition containing 15 wt % or more of polyfunctional polymerizable compounds and 15 wt % or more of a monofunctional polymerizable compound A or B;
wherein all weight percentages wt % are based upon the total weight of the polymerizable composition in the pigmented free radical curable inkjet ink or the polymerizable composition in the free radical curable liquid;
wherein monofunctional polymerizable compound A is a compound according to Formula (1):

wherein Q represents the necessary atoms to form a five to eight membered ring and the dashed line represents a covalent bond to a carbon atom; and
wherein monofunctional polymerizable compound B is a compound according to Formula (2):
