摘要

Method for impregnating lignocellulosic material with effect agents, comprises impregnating the lignocellulosic material with a fluid formation, which contains at least one effect agent in a dissolved or dispersed form; impregnating the material with a hardenable aqueous composition, which contains at least one cross-linkable compound; and treating the material obtained at an elevated temperature. Method for impregnating lignocellulosic material with effect agents, comprises impregnating the lignocellulosic material with a fluid formation, which contains at least one effect agent in a dissolved or dispersed form; impregnating the material with a hardenable aqueous composition, which contains at least one cross-linkable compound such as low-molecular weight compounds (V), having at least two N-bonded groups of formula (CH 2OR) and/or one 1,2-bishydroxyethane-1,2-diyl group, bridging two nitrogen atoms, precondensates the compound (V), and reaction products or mixtures of the compound (V) with at least one alcohol such as 1-6C alkanols, 2-6C polyols and oligoalkylene glycols; and treating the material obtained at an elevated temperature. R : H or 1-4C alkyl. Independent claims are also included for: (1) a lignocellulosematerial, is obtained by the process; and (2) an aqueous composition comprising dissolved or dispersed form of effect agent and hardenable compound.
