Zusammenfassung:	The invention relates to a method for preparing a densified wood article comprising vacuum impregnating a porous low-density type of wood with a specified aqueous phenol-formaldehyde resin composition and pressing. The invention also relates to a densified wood article obtainable by the process having a very low set-recovery. The invention further relates to an aqueous phenol-formaldehyde resin composition according to the invention, a method process for the preparation thereof and to the use thereof in a method for preparing a densified wood article. The densified wood article can be used in high value-added applications like flooring or furniture.
