    Abstract: The invention relates to a method for producing wood-based materials comprising at least one flat thin veneer layer glued with a support or other veneer layers consisting i) in impregnating a veneer with an aqueous hardenable composition which a) comprises at least one type of cross-linkable urea compound selected from urea compounds H containing at least one N-bonded group of formula CH 2 OR, wherein R is hydrogen or C 1 -C 4 -alkyl, and/or a 1,2-bishydroxyethane-1,2-diyl group containing two urea nitrogen atoms, urea compound H precondensates and reaction products or mixtures of the urea compound H with at least one type of alcohol selected from C 1 C 6 -alkanols, C 2 -C 6 -polyols and oligo ethylene glycols and b) at least one type of catalyst K producing urea compound cross-linking, ii) in gluing the impregnated veneer with an adhesive composition and iii) in transforming the glued veneer into a wood-based material at a high temperature, along with hardening a cross-linkable urea compound, wherein the veneer impregnated prior to gluing at a stage ii) comprises a substantially uncross-linked cross-linkable urea compound.

    Abstract: The present invention relates to a process for the production of wood-base materials which have at least one thin veneer layer adhesively bonded over the surface to a substrate or to further veneer layers, which process comprises the following steps: i. impregnation of a veneer with an aqueous curable composition which comprises a) at least one curable urea compound selected from urea compounds H which have at least one N-bonded group of the formula CH2OR, where R is hydrogen or C1-C4-alkyl, and/or a 1,2-bishydroxyethane-1,2-diyl group bridging the two nitrogen atoms of the urea, precondensates of the urea compound H, and reaction products or mixtures of the urea compound H with at least one alcohol which is selected from C1-C6-alkanols, C2-C6-polyols and oligoethylene glycols, and b) at least one catalyst K effecting crosslinking of the urea compound; ii) gluing of the impregnated veneer and/or the substrate with a glue composition and iii) processing of the glued veneer to give a wood-base material at elevated temperature with curing of the crosslinkable urea compound, the impregnated veneer comprising the crosslinkable urea compound in substantially uncrosslinked form before the gluing in step ii).

    Abstract: The invention relates to a method for producing modified lignocellulosic materials. Said method consists of the following steps a) the lignocellulosic material is impregnated with an aqueous composition which contains i) at least one cross-linkable nitrogen compound and ii) at least one substance which catalyses the cross-linking, b) the impregnated lignocellulosic materials are treated at higher temperatures in order to remove the water and to cross-link the cross-linkable nitrogen compound. In step b) the impregnated lignocellulosic material is treated with overheated steam. The invention also relates to lignocellulosic materials which are obtained according to said method.
