1. A water-dilutable concentrate or an aqueous composition for treating wood, containing - an organic binder which dries in air with the aid of a siccative, which is rendered water-soluble with the aid of a salt-former and the macromolecules of which are based on an unsaponifiable hydrocarbon chain, - optionally one or more water-insoluble, organic woodprotecting agents and/or one or more water-soluble woodprotecting agents, and - optionally additives conventional in the impregnation and coating industries, pore-closing additives being excluded, characterised in that - the binder is one or more carboxylated 1,3-(cyclo)diene polymers having an acid number of 50 to 250 [mg KOH/g], an (average) content of olefinic double bonds corresponding to an iodine number of >= 200 [g iodine/100g] and a relative molecular weight (Mn ) of 500 to 5000, provided that if more than one polymer is present none of them has an iodine number of < 100, and - the carboxyl groups of the binder are partially or completely neutralised with the aid of a base selected from alkali metal hydroxides, alkali metal carbonates, alkali metal bicarbonates, ammonia, lower molecular weight water-soluble monoamines which do not inhibit air drying, and their mixtures, so that the pH value of the treating composition is 6 to 11.5, the strength and amount of base (degree of neutralisation) on the one hand and the structural parameters governing the water-solubility on the other hand being so related to one another that the binder is water-soluble or is present in dissolved form, as the case may be.
