ABSTRACT:
The invention relates to a lignocellulose material comprising a crosslinkable nitrogen compound, technically a formaldehyde condensate, in crosslinked form in a constituent amount (N) of at least 1% by weight, calculated as nitrogen and based on the total weight of the lignocellulose material, in which the ratio (FA/N) of formaldehyde emission (FA), determined by means of the bottle method according to EN 717, part 3, to constituent amount of the nitrogen compound (N) exhibits a value of at most 5.0×10−3, and to a process for the preparation thereof.
