The present invention relates to a process for the production of modified veneer materials. The method according to the invention comprises the following steps: i) impregnating an unmodified veneer with an aqueous curable composition comprising a) at least one crosslinkable urea compound H, which is at least one N-bonded group of the formula CH 2 OR, wherein R is hydrogen or C 1 -C 4 alkyl, and / or a two nitrogen atoms of the urea bridging 1,2-bishydroxyethane Having -1,2-diyl group, and b) contains at least one substance catalyzing the crosslinking, ii) pressing the impregnated veneer at elevated temperature, iii) gluing the veneer and / or the carrier obtained in step ii), and iv) surface bonding of glued veneer with a carrier or other veneer layers to the veneer material. |
