    摘要： A multilayer lignocellulose-containing molding comprising A) a middle layer or a plurality of middle layers comprising lignocellulose-containing particles which is/are obtainable by using a binder (a) and B) a covering layer or a plurality of covering layers comprising lignocellulose-containing particles which is/are obtainable by using a binder (b), the binder (a) being selected from the group consisting of (a1) formaldehyde resins and (a2) an organic isocyanate having at least two isocyanate groups; the binder (b) comprising the following components: an aqueous component (I) comprising (i) a polymer A which is composed of the following monomers: a) from 70 to 100% by weight of at least one ethylenically unsaturated mono- and/or dicarboxylic acid (monomer(s) A1) and b) from 0 to 30% by weight of at least one further ethylenically unsaturated monomer which differs from the monomers A1 (monomer(s) A2) and, optionally, (ii) a low molecular weight crosslinker having at least two functional groups which are selected from the group consisting of hydroxyl, carboxyl and derivatives thereof, primary, secondary and tertiary amine, epoxy, aldehyde and, optionally, a component (II), as an aqueous dispersion, comprising one or more polymer(s) M which is composed of the following monomers: a) from 0 to 50% by weight of at least one ethylenically unsaturated monomer which comprises at least one epoxide and/or at least one hydroxyalkyl group (monomer(s) M1) and b) from 50 to 100% by weight of at least one further ethylenically unsaturated monomer which differs from the monomers M1 (monomer(s) M2) and, optionally, customary additives as component (III), and, where the binder (a) comprises a formaldehyde resin, the binder (b) comprising formaldehyde scavengers.
