摘要

WATER COMPOSITION OF ACTIVE SUBSTANCE, PROCESS FOR REPAIRING AN ACTIVE SUBSTANCE COMPOSITION, USE OF AN ACTIVE SUBSTANCE COMPOSITION, AND PROCESS FOR PROTECTION OF MATERIALS UNDERSTANDING CELLULOSIS AGAINST INFESTATIONS its use to combat harmful microorganisms and particularly to protect cellulose-containing materials, especially wood, from attack by microorganisms, particularly harmful fungi that may damage wood or cellulose. The active substance compositions of the invention contain: a) at least one fungicidal active organic substance having a degree of water solubility of not greater than 5 g / 1 at 25 RTI A fine particle size having an average particle size (determined by dynamic light scattering) of not more than 300 nm, in which the polymer particles contain the active substance, in which the polymer is constructed of ethylenically unsaturated monomers M, comprising: at least 60% by weight, based on the total amount of monomers M, of at least one neutral mono-ethylenically unsaturated monomer M1 having a degree of water solubility of not more than 30 g / l at 25 ° C and up to 40% by weight for the total amount of M monomers of one or more M2 ethylenically unsaturated monomers different from M1 monomers.
