MANUFACTURING OF DECORATIVE LAMINATES BY INKJET

A method for manufacturing decorative laminates includes the steps of a) impregnating a paper substrate with a thermosetting resin by submersion of the paper substrate in a bath of thermosetting resin; b) applying on the thermosetting resin impregnated paper substrate an ink acceptance layer containing an inorganic pigment P and a polymeric binder B having a weight ratio P/B of inorganic pigment to polymeric binder of larger than 1.5; c) jetting on the ink acceptance layer a colour pattern with one or more aqueous pigmented inkjet inks and/or organic solvent based pigmented inkjet inks containing a colour pigment C; and d) heat pressing the thermosetting paper into a decorative laminate, wherein the weight ratio P/C of the inorganic pigment of the ink acceptance layer to the jetted colour pigment in the colour pattern is larger than 4.0.
