FIELD: wood treatment.

SUBSTANCE: invention refers to the method of wood treatment which includes wood treatment with wood conserving agent including copper and copolymer latex containing polymerized parts of X monomer and Y monomer. At this copolymer latex contains at least 5 mas.% of parts received from X monomer, no more than 1000 mas. part/mln. of remaining X monomer. X monomer is chosen of the group including vinylimidazoles, vinylimidazolins, vinylpyridines, vinylpyrroles, vinylpyrrolidones, vinylcaprolactams, their derivatives and their combinations. Y monomer is chosen of the group including carboxylic acids, carboxylic acid salts, carboxylic acids ethers, organosulfur acids, organosulfur acid salts, sulfonic acids, sulfonic acid salts, phosphonic acids, phosphonic acid salts, vynil complex ethers, (meth)acrylamides, (C₈-C₂₀) aromatic monomers containing at least one exocyclic ethylenically unsaturated group and their combinations.

EFFECT: suppression of copper compounds discharge into the environment.
