FIELD: building.
SUBSTANCE: invention can be used to manufacture a staining-resistant coating for wood, concrete, or plaster. Coating composition contains an aqueous dispersion of self-crosslinking particles with a core-shell structure, and a hydrophobic additive. The core-shell particles contain an encapsulated polymer core covalently bound with a polymer shell containing urethane bonds, keto and/or aldo functional groups and hydrazide functional groups. The hydrophobic additive is non-reactive, has a polymer core and a polymer shell, and constitutes a wax and/or a silicon-containing compound. Also proposed are a substrate with an at least partially applied coating and a method for increasing the staining resistance of the substrate.
EFFECT: increase in the resistance of the outer coating produced from the proposed composition to staining caused by the entry of dirt from the environment.
