    Abstract: The multi-layered lignocellulosic molded bodies comprise middle layer containing lignocellulosic particles and obtained through the use of binder (a), and two cover layers containing lignocellulosic particles and obtained through the use of binder (b). The binder (a) is formaldehyde resins (a1) and an organic isocyanate (a2) with two isocyanate groups. The binder (b) contains aqueous component (I) comprising polymer (A) constructed of monomers (A1) having 70-100 wt.% of ethylenically unsaturated mono- and/or dicarboxylic acids and 0-30 wt.% of other ethylenically unsaturated monomers (A2). The multi-layered lignocellulosic molded bodies comprise a middle layer containing lignocellulosic particles and obtained through the use of a binder (a), and two cover layers containing lignocellulosic particles and obtained through the use of a binder (b). The binder (a) is formaldehyde resins (a1) and an organic isocyanate (a2) with two isocyanate groups. The binder (b) contains an aqueous component (I) comprising a polymer (A) constructed of monomers (A1) having 70-100 wt.% of ethylenically unsaturated mono- and/or dicarboxylic acids and 0-30 wt.% of other ethylenically unsaturated monomers (A2) that differ from the monomers (A1), and optionally a low molecular weight cross-linking agent comprising two functional groups of hydroxy, carboxylic acid and its derivatives, primary, secondary and tertiary amine, epoxy and aldehyde, and optionally a component (II) as an aqueous dispersion comprising polymers (M) constructed from the monomers having 0-50 wt.% of ethylenically unsaturated monomer (M1) containing an epoxide group and/or hydroxyalkyl group, and 50-100 wt.% of other ethylenically unsaturated monomer (M2) that differs from the first monomer (M1), and optionally conventional additives as component (III), where the binder (b) contains formaldehyde traps and formaldehyde resin. The binder (b) consists of low molecular cross-linker as the component (II). The binder (a) consists of 70-99.9 wt.% of component (a1) and 0.1-30 wt.% of component (a2) related to the total (a1) and (a2) of the pure undiluted substances. The molded bodies are formed in the form of plate. An independent claim is included for a method for the production of multi-layered lignocellulosic molded bodies.
